American Guide to Buying Property in Japan: FBAR, FATCA, and What US Citizens Must Report

I have helped buyers from Australia, the UK, Singapore, Switzerland, and a dozen other countries purchase mountain properties in Nagano Prefecture. Americans, without exception, have the most complicated tax situation of any nationality I work with. Not because Japan treats you differently. Japan does not. You can buy property here just as freely as anyone else. The complication comes entirely from the United States government's insistence on taxing its citizens on worldwide income, wherever they live and wherever that income originates.

This guide is written specifically for US citizens considering a vacation home or rental property in Hakuba, Nozawa Onsen, or the surrounding Nagano mountain valleys. I will walk you through the key reporting obligations, FBAR, FATCA, Japanese withholding tax for non-residents, capital gains on both sides of the Pacific, and explain what kind of professional help you will genuinely need. I am not a tax advisor, and nothing here is legal or tax advice. What I am is someone who has watched American buyers navigate this process successfully, and occasionally stumble on details that could have been avoided with better preparation.

Why Americans Are Different: Worldwide Taxation

The United States is one of only two countries in the world, the other is Eritrea, that taxes its citizens based on citizenship rather than residency. Every other nation taxes on the basis of where you live. Move to Japan, become a Japanese tax resident, and Germany stops taxing your income. Canada stops. Australia stops. The UK stops.

The US does not stop.

If you are a US citizen living in Los Angeles and you own a chalet in Hakuba that generates 7 million yen a year in Airbnb rental income, the IRS considers that your income. You will report it. You will pay US tax on it, with credit for Japanese taxes you have already paid. The same applies when you sell. Your capital gain is a US capital gain as well as a Japanese one, and both countries want to know about it.

This is not a reason to avoid buying in Japan. Many Americans own ski properties here and manage the tax picture without drama. But it does mean you need a tax professional who understands international US taxation before you sign anything, not after. I will come back to what that expertise looks like and how rare it is.

Can Americans Buy Property in Japan?

Yes, completely freely. Japan has no restrictions on foreign ownership of real estate. There is no minimum purchase price, no approval process, no requirement to use a Japanese partner, no limit on how many properties you can own. You can buy as an individual under your own name, or through a Japanese company structure if that makes sense for your situation.

The one obligation that came into effect in April 2026, applying to all foreign nationals, not specifically Americans, is FEFTA notification. FEFTA stands for the Foreign Exchange and Foreign Trade Act. Under the revised rules that took effect April 1, 2026, every non-resident who acquires Japanese real estate must notify the Minister of Finance, through the Bank of Japan, within 20 days after the purchase is completed. Before that date, property bought for the buyer's own use was exempt; that exemption has been removed, so the report now applies to all acquisitions, a Hakuba holiday chalet included. Your real estate agent or judicial scrivener (the professional who handles title registration in Japan) will guide you through this filing. It is administrative rather than burdensome. You are not asking for permission, you are informing the government of a completed transaction.

Beyond FEFTA, the Japanese purchase process for a non-resident foreigner is essentially the same as for anyone else. You need a Japanese bank account, a Residence Card or official documentation, and an Individual Number (My Number) if you plan to receive rental income in Japan. Your judicial scrivener handles the title registration. Your real estate agent coordinates the contract and handover.

FBAR: The Foreign Bank Account Report

This is the one that surprises many buyers, because it has nothing directly to do with property. FBAR stands for Foreign Bank Account Report, filed on FinCEN Form 114 with the Financial Crimes Enforcement Network, which sits within the US Treasury. It is separate from your IRS tax return.

The rule: if you have a financial interest in, or signature authority over, any foreign financial account, including bank accounts, brokerage accounts, certain pension accounts, and the aggregate value of all such accounts exceeds USD 10,000 at any point during the calendar year, you must file an FBAR for that year.

When you buy property in Japan, you will almost certainly open a Japanese bank account. You need one to pay ongoing costs: utilities, management fees, property taxes, and eventually to receive rental income. The moment that account holds more than the equivalent of USD 10,000, which will happen the moment you wire the purchase funds through it, or when you accumulate rental income, you have an FBAR filing requirement.

Key FBAR facts:

  • Form: FinCEN 114 (not a tax form, separate system)
  • Filing platform: BSA E-Filing System (fincen.gov)
  • Deadline: April 15, with automatic extension to October 15
  • Threshold: USD 10,000 aggregate at any point in the year
  • Penalty for willful failure: greater of USD 165,353 or 50% of account balance per violation (inflation-adjusted FinCEN figure, effective January 2025)
  • Penalty for non-willful failure: up to USD 16,536 per annual report (inflation-adjusted by FinCEN effective Jan 2025; per Bittner v. US (2023), penalty is per annual report, not per account)
  • Japanese property itself: NOT reported on FBAR, only financial accounts

The penalties for willful non-compliance are genuinely severe. The IRS and FinCEN have been increasingly active in enforcing FBAR requirements, and the courts have generally upheld substantial penalties even for taxpayers who were simply unaware of the obligation. Unawareness is not a complete defense, though it can be a mitigating factor in penalty calculations for non-willful failures.

Your Japanese bank account is the primary FBAR concern for most property buyers. If you also invest in Japanese securities or hold a Japanese brokerage account, those must be reported as well. The Japanese real estate itself is not a financial account and is not reported on the FBAR. It is handled differently through FATCA and your tax return.

A practical note: when you wire money from the US to Japan to fund a property purchase, that wire transfer itself is not the filing trigger. The trigger is the account balance exceeding USD 10,000 at any point. Given that you will be wiring millions of dollars equivalent to complete a purchase, your account will be well above the threshold. File the FBAR for that year without question.

FATCA: The Foreign Account Tax Compliance Act

FATCA, enacted in 2010, operates on two levels. First, it requires foreign financial institutions, including Japanese banks, to report information about accounts held by US persons to the IRS. Japan and the US have a bilateral FATCA agreement (an Intergovernmental Agreement, or IGA), which means Japanese banks report to Japan's National Tax Agency, which then shares the information with the IRS. The practical result: the IRS already knows about your Japanese bank account if your bank has your US passport or Social Security Number on file, which it will after you complete standard KYC (Know Your Customer) procedures.

Second, FATCA requires US taxpayers to report their foreign financial assets on Form 8938 (Statement of Specified Foreign Financial Assets), attached to their annual Form 1040.

Form 8938 filing thresholds:

  • Single filer living in the US: USD 50,000 at year-end or USD 75,000 at any point
  • Married filing jointly, living in the US: USD 100,000 at year-end or USD 150,000 at any point
  • Single filer living outside the US: USD 200,000 at year-end or USD 300,000 at any point
  • Married filing jointly, living outside the US: USD 400,000 at year-end or USD 600,000 at any point

Here is where it gets slightly technical for property buyers: Japanese real estate is not a "specified foreign financial asset" in the way a bank account is. The property itself does not appear on Form 8938. However, if you hold interests in a Japanese company that owns property (for example, a Godo Kaisha or Kabushiki Kaisha used as a holding structure), that entity interest may be a specified foreign financial asset.

For most individual buyers purchasing property in their own name, which is the simplest structure and what most vacation home buyers do, the main Form 8938 concern is your Japanese bank account and any other financial accounts exceeding the thresholds above.

Both FBAR and Form 8938 can apply to the same accounts simultaneously. They are parallel obligations, not alternatives. Your tax professional will file both.

US Income Tax on Japanese Rental Income

When your Hakuba or Nozawa Onsen property generates rental income, Airbnb stays at 65,000 to 150,000 yen per night during ski season, or longer-term rentals generating 6 to 10 million yen annually for a quality four-bedroom, you report that gross income on your US tax return on Schedule E.

The mechanics look like this. You convert the yen income to USD at the IRS-approved exchange rates (typically the average annual rate or transaction-date rates). That USD figure goes on Schedule E as gross rental income. You then deduct allowable expenses.

Allowable deductions on US Schedule E for Japanese rental property:

  • Property management fees: typically 10-20% of gross rent in Japan for non-resident landlords
  • Repairs and maintenance: distinguishable from capital improvements, which must be depreciated
  • Insurance: Japanese fire and earthquake insurance
  • Japanese property taxes (kotei shisanzei): deductible as rental expense
  • Mortgage interest: if you have a Japanese mortgage, which is uncommon for foreigners
  • Professional fees: portion of tax preparation attributable to rental
  • Depreciation: see separate section below

After deducting allowable expenses, you have net rental income, which is taxed at your ordinary income rate in the US. However, you also report, and receive credit for, Japanese taxes paid on the same income. This is the Foreign Tax Credit, filed on Form 1116.

The Foreign Tax Credit prevents true double taxation in most cases. Japan taxes non-resident landlords at 20.42% withholding on gross rental income (discussed in more detail below). That 20.42% Japanese tax becomes a credit against your US tax liability on the same income. If your effective US rate on that income is, say, 32%, you pay the difference, roughly 11-12 percentage points, to the IRS. You are not paying 20.42% to Japan and then 32% again to the US. The credit eliminates the overlap.

The mathematics can get complicated when you have other foreign income, loss carryforwards, or passive activity loss rules interact with your rental income. This is not a topic to navigate without professional guidance.

Depreciation of Japanese Property for US Tax Purposes

In the US, residential rental property is depreciated over 27.5 years under the Modified Accelerated Cost Recovery System (MACRS). This is one of the most valuable tax benefits of owning domestic rental property. You can deduct roughly 3.6% of the building value each year as a non-cash expense, reducing your taxable income without reducing your bank balance.

For foreign residential rental property, the rules are less favorable. Under the Alternative Depreciation System (ADS), which is required for foreign property, the depreciation period is 30 years rather than 27.5 years, a change introduced by the Tax Cuts and Jobs Act of 2017, effective for property placed in service after December 31, 2017. You can depreciate approximately 3.33% of the building value each year, not 3.6%.

This is a meaningful difference over a 10 or 20-year holding period, but it is still a real deduction. On a 40-million-yen property where the building component might be valued at 25 million yen (roughly USD 165,000 at current rates), you would claim approximately USD 5,500 per year in depreciation, a deduction against ordinary income.

A few Japan-specific points that complicate this calculation. First, Japan has its own depreciation schedule for buildings, which varies by construction type. Wooden structures depreciate faster (22 years under Japanese law); reinforced concrete structures depreciate more slowly (47 years). You will be calculating depreciation separately for US and Japanese purposes using different schedules and different cost bases. Second, when you sell the property, the IRS requires depreciation recapture. You pay tax on the cumulative depreciation you have claimed at rates up to 25%. This is not avoidable and should factor into your long-term return calculations.

Capital Gains When You Sell

If you sell your Japanese property after holding it for more than one year, the gain is a long-term capital gain in the US. Long-term capital gains rates are 0%, 15%, or 20% depending on your taxable income. For most buyers at the income levels that support a 30 to 80 million yen vacation home, you are likely looking at the 15% or 20% rate.

In addition to the capital gains rate, the Net Investment Income Tax (NIIT) of 3.8% applies to investment income, including capital gains from rental property, for taxpayers with modified adjusted gross income above USD 200,000 (single) or USD 250,000 (married filing jointly). So your effective US capital gains rate on a property sale could be 18.8% (15% + 3.8%) or 23.8% (20% + 3.8%).

Japan also taxes capital gains on property sold by non-residents. The Japanese rate for non-residents on long-term gains (held more than 5 years) is 15.315% national tax (including the reconstruction surtax) plus 5% local tax, for a combined 20.315%. For short-term gains (held 5 years or less), the rate is 30.63% national (including reconstruction surtax) plus 9% local, for a combined 39.63%. The 5-year holding period in Japan is calculated as of January 1 of the year of sale, not from the purchase date, which can catch people off guard.

You use the Foreign Tax Credit (Form 1116) to credit Japanese capital gains tax against your US capital gains tax liability on the same gain. The interaction is not always dollar-for-dollar. The foreign tax credit has limitations and baskets. But in most scenarios, you will not pay full rates in both countries.

Summary comparison of capital gains treatment:

  • Japan (non-resident) long-term threshold: 5+ years (as of Jan 1 in sale year)
  • Japan long-term rate: 20.315% (15.315% national incl. reconstruction surtax + 5% local)
  • Japan short-term rate: 39.63% (30.63% national incl. reconstruction surtax + 9% local)
  • United States long-term threshold: more than 1 year
  • United States long-term rate: 15-20% plus possible 3.8% NIIT
  • United States short-term rate: ordinary income rate (up to 37%)
  • Foreign Tax Credit: available in US for Japanese taxes paid
  • Depreciation recapture: separate rules in Japan; up to 25% for recaptured depreciation in the US

One important point: the gain is calculated in US dollars, using the exchange rates at purchase and sale. If you purchase in 2025 when the yen is at 155 per dollar and sell in 2035 when the yen has strengthened to 120 per dollar, you have a currency gain on top of any property appreciation, and that currency gain is taxable in the US. Conversely, if the yen weakens further, you could have a property gain in yen terms but a smaller gain or even a loss in dollar terms. Currency risk is real and bidirectional.

The Japanese Side: Withholding Tax and Annual Filing for Non-Resident Landlords

While I want this guide to focus on the US-specific obligations that distinguish American buyers, I need to explain the Japanese side clearly because the two systems interact.

As a non-resident foreign landlord in Japan, you are subject to a 20.42% withholding tax on gross rental income. This withholding is typically handled through a "withholding agent," either your property manager or your Japanese tenant. If you use a professional property management company, they will handle this, remit the withheld tax to the Japanese tax authorities on your behalf, and provide you with documentation at year-end. This documentation is what you use to claim the Foreign Tax Credit on your US return.

The 20.42% rate is on gross income, before any deductions. Japan does allow non-resident landlords to file an annual Japanese tax return and claim deductions (management fees, repairs, depreciation under Japanese rules, insurance, and property taxes), which can significantly reduce your Japanese tax liability from the initial withholding amount. Whether you file depends on whether a refund is available. In many cases, claiming deductions through an annual filing makes sense and results in a partial refund of withheld amounts.

A Japanese tax accountant (zeirishi) familiar with non-resident landlord rules will handle this filing. The annual Japanese tax filing deadline for non-residents is March 15 of the following year (the same as for residents), though extensions are available through appointed tax representatives.

Annual holding cost structure for a typical Hakuba or Nozawa Onsen property:

  • Fixed asset tax (kotei shisanzei): 150,000 to 400,000 yen annually
  • City planning tax (toshi keikaku zei): 30,000 to 100,000 yen annually
  • Property management fee (10-20% of gross rent): 600,000 to 2,000,000 yen annually
  • Insurance (fire + earthquake): 60,000 to 150,000 yen annually
  • Utilities (when not rented): 60,000 to 180,000 yen annually
  • Minor repairs and maintenance: 100,000 to 300,000 yen annually
  • Japanese tax accountant (annual filing): 150,000 to 300,000 yen annually
  • US tax preparation (international specialist): USD 3,000 to 8,000 annually

The total holding cost before major repairs, and excluding the US tax preparation fee, runs roughly 600,000 to 1,300,000 yen annually for a well-maintained vacation rental property. Against gross rental income of 6 to 10 million yen for a quality four-bedroom property in peak locations, the economics can be compelling.

Wire Transfers and Banking: What Actually Happens

When you wire several hundred thousand dollars to Japan to purchase property, you are not doing anything suspicious or unusual. Banks, however, are required to file Suspicious Activity Reports (SARs) for transactions above certain thresholds and for patterns that suggest money laundering. A large wire to Japan triggers automatic reporting procedures at your US bank, not because you have done anything wrong, but because the system requires it for all large international transfers.

This does not affect your transaction. The SAR goes to FinCEN as a routine compliance filing. Provided your funds have a legitimate documented source, salary, investment proceeds, an existing property sale, there is no issue.

What you should do proactively is prepare documentation of your fund source before the wire. Your US bank may ask for it. The Japanese receiving bank will likely ask for it as well. Japanese banks take anti-money-laundering compliance seriously and have become more thorough in recent years. An explanation letter describing the source of funds, accompanied by relevant documentation (tax returns, brokerage statements, prior property sale records), smooths the process considerably.

FBAR and FATCA are reporting obligations. They do not restrict your ability to move money. There is no US law preventing you from holding assets in Japan or transferring dollars to yen. The obligations are about transparency, ensuring the IRS knows about your foreign financial assets and income, not about limiting what you can own or where you can invest.

The Professional Team You Need

This is where I want to be direct, because I have seen buyers underestimate this. Managing a Japanese vacation rental property as a US citizen requires a multi-country professional team, and the most critical and rarest member of that team is a US CPA with genuine international tax expertise.

What a qualified US CPA for this situation must know:

  • Form 1116 (Foreign Tax Credit) including passive category income and the credit limitation calculations
  • Schedule E for foreign rental property
  • FBAR requirements and FinCEN 114 filing
  • Form 8938 (FATCA) and the distinction between financial accounts and other foreign assets
  • Foreign residential rental property depreciation under ADS (30-year schedule for property placed in service after 2017)
  • Net Investment Income Tax and how rental income and capital gains interact with it
  • Passive activity loss rules as they apply to rental property owned by non-resident landlords
  • Depreciation recapture on sale

This is not a standard skillset. Many CPAs who handle international clients focus on expats, people living abroad who claim the Foreign Earned Income Exclusion (Form 2555). Your situation is different: you are not living in Japan, you are not claiming the Foreign Earned Income Exclusion (which applies to earned income, not rental income), and your complexity comes from the interaction between foreign rental income and domestic US tax obligations. Make sure your CPA has specifically handled non-resident US citizens with Japanese rental income before, not just expats abroad.

The Japanese side requires a Japanese zeirishi (tax accountant) familiar with non-resident landlord rules. This is a more common specialization in resort areas like Hakuba, where the number of foreign property owners has grown substantially.

Ideally, you want these two professionals aware of each other and coordinating around year-end, specifically, the timing and documentation of Japanese withholding tax, which flows into the US Foreign Tax Credit calculation.

Professional team for an American buyer with Japanese rental property:

  • US CPA (international tax): FBAR, FATCA, Schedule E, Form 1116, capital gains. US-based, specialization in international/Japan practice.
  • Japanese zeirishi: annual Japanese non-resident tax filing, withholding documentation. Hakuba/Nozawa area, or Tokyo-based with non-resident clients.
  • Property manager (kanri kaisha): tenant management, withholding agent, maintenance coordination. Local to your resort area.
  • Judicial scrivener (shiho shoshi): title registration, FEFTA notification. Local, introduced through your real estate agent.
  • Real estate agent: property search, contract, liaison. Local expert.

The Acquisition Cost Reality

Before going further, let me give you the real numbers for acquisition costs, because these affect your financial model and are sometimes understated in promotional material.

On a property purchase in Japan, total acquisition costs typically run 5 to 8% of the purchase price. The main components:

  • Stamp duty (印紙税) on purchase contract: 10,000 to 60,000 yen depending on price
  • Registration license tax (登録免許税): approximately 2% of assessed value for title transfer
  • Judicial scrivener fees: 100,000 to 200,000 yen
  • Real estate agent commission: 3% of purchase price + 60,000 yen + consumption tax
  • Fixed asset tax adjustment (prorated): varies by purchase timing
  • Fire and earthquake insurance (initial): 100,000 to 300,000 yen
  • Renovation costs: highly variable; can dwarf acquisition costs

For a 40-million-yen property, expect 2 to 3.2 million yen in pure acquisition costs before any renovation. If the property requires work, and many mountain properties do, whether older traditional structures or dated ski chalets, renovation costs are entirely separate and can range from 2 to 3 million yen for cosmetic work to 15 to 20 million yen or more for significant structural renovation of an older building.

The 30 to 80 million yen total budget I work with most of my clients on typically means 15 to 50 million yen for the property itself and the remainder for renovation, depending on what the property requires. Many of the most rewarding purchases I have been involved in were properties that needed significant work and were priced accordingly.

A Note on Hakuba Specifically

I want to give you context on why Hakuba attracts the international investment interest it does, because understanding the market helps frame the decision.

Hakuba hosted the alpine skiing, ski jumping, and biathlon events at the 1998 Nagano Winter Olympics. Happo-One, the main resort, has a summit at 1,831 meters and connects with 8 other resorts across the valley. The snow is what the Japanese ski community calls "Japow," a dry powder with 3 to 5% moisture content, compared to 10 to 20% for typical European Alps snow. For skiers accustomed to Central European conditions, the quality difference is immediately apparent.

The commercial land price data tells the investment story: Hakuba saw commercial land appreciation of 30.2% in 2024 alone, ranking fourth nationally among all Japanese municipalities. This is not speculation. It reflects genuine demand pressure from international buyers and the limited supply of well-located properties near lifts.

For American buyers looking specifically at ski-resort vacation rentals with Airbnb income, the international character of the Hakuba visitor base is relevant. The village has well-established English-language services, bilingual property managers, and a hospitality infrastructure oriented toward foreign guests. Finding management support if you do not speak Japanese is feasible here in a way it might not be in less-touristed mountain areas.

FAQ

Do I need to pay US tax on my Japanese rental income if I already pay Japanese tax in Japan?

Yes, you must declare the rental income on your US tax return, but you will receive credit for Japanese taxes already paid. The Foreign Tax Credit (Form 1116) prevents full double taxation. Japan withholds 20.42% from gross rental income for non-resident landlords. That Japanese tax becomes a credit against your US tax liability on the same income. If your effective US rate on the income exceeds the Japanese rate, you pay the difference to the IRS. If the Japanese rate exceeds your US rate, which is less common but can happen depending on your income bracket, excess credits can be carried back one year or forward ten years. You will owe US tax, but the credit ensures you are not paying the full rate twice on the same income.

Does the IRS know if I buy property overseas?

Not automatically through the purchase itself. Japanese real estate is not a financial account and is not reported under FATCA by Japanese institutions. However, your Japanese bank account is reportable under FATCA, and Japanese banks report US account holders to Japan's National Tax Agency, which shares information with the IRS. When you sell a property and repatriate funds, the wire transfers will be visible to banking systems. Additionally, you are legally required to declare rental income and capital gains on your US tax return, which creates a record. Choosing not to report because "the IRS won't know" is not a sound strategy. The reporting architecture around international banking has become substantially more comprehensive since 2010.

What happens if I miss an FBAR filing?

The consequences depend on whether the failure is classified as "non-willful" or "willful." Non-willful failures carry penalties up to USD 16,536 per annual report (the inflation-adjusted maximum as of 2025); under Bittner v. United States (2023) the penalty applies per annual FBAR report, not per account, and there is some enforcement discretion. Willful failures carry penalties up to the greater of USD 165,353 (inflation-adjusted from the statutory USD 100,000 base, effective January 2025) or 50% of the account balance per violation, potentially enormous for accounts holding property purchase funds. If you realize you have missed FBAR filings, there are IRS voluntary disclosure programs and streamlined procedures (Streamlined Domestic Offshore Procedures for US residents, Streamlined Foreign Offshore Procedures for those living abroad) that allow you to come into compliance with reduced penalties. Acting proactively is significantly better than waiting to be discovered. Engage a qualified tax attorney or CPA who specializes in FBAR compliance before doing anything.

Can I put my Japanese property in a US LLC or trust to simplify the tax situation?

Possibly, but it adds complexity rather than reducing it, and it does not eliminate US tax obligations. Owning Japanese real estate through a US LLC is sometimes done for estate planning or liability reasons, but the LLC is treated as a disregarded entity for US tax purposes if single-member, meaning you still report everything on your personal return. Owning through a Japanese entity (a Godo Kaisha) can have advantages for operational reasons, but the entity itself may become a reportable foreign financial asset. Trust structures that include foreign property have their own reporting requirements. Any structure decision should be made with qualified legal and tax advice before purchase, not retrofitted afterward.

How does the 5-year rule work for Japanese capital gains tax?

Japan calculates the holding period as of January 1 of the year in which you sell, not from the actual purchase date. If you purchased in December 2023 and sell in February 2028, you might think you have held for more than 4 years. But as of January 1, 2028 (the reference date), you have held only from December 2023 to January 1, 2028, which is approximately 4 years and 1 month. Japan would count this as short-term. The trap is the January 1 cut-off: a buyer who purchases in December 2023 and sells at any point in 2028 is short-term, because the holding period as of January 1, 2028 is still under 5 years. To qualify for the 20.315% long-term rate, that same buyer would need to sell in 2029 or later, because as of January 1, 2029 the holding period would be more than 5 years. The practical implication is that you should generally plan a minimum holding period well past the 5-year mark from purchase, and consult a Japanese tax accountant about the exact calculation before setting a sale timeline. The difference in rate between short-term 39.63% and long-term 20.315% is substantial enough to make timing worth planning carefully.

What is Form 8938 and is it different from FBAR?

Both are foreign asset reporting requirements, but they serve different functions and go to different agencies. FBAR (FinCEN 114) is filed with the Financial Crimes Enforcement Network and covers foreign bank and financial accounts above USD 10,000 aggregate. Form 8938 is filed with your IRS tax return (Form 1040) and covers specified foreign financial assets above certain thresholds, USD 50,000 for single filers living in the US. The thresholds, definitions, and purposes differ, but both can apply simultaneously to the same Japanese bank account. They are not alternatives to each other. Your tax professional will determine whether you need to file one, the other, or both in any given year.

I am planning to renovate before renting. How does this affect my US tax position?

Renovation costs that improve the property, new kitchen, new bathrooms, structural work, additions, are capital improvements and must be added to your cost basis and depreciated over time rather than expensed immediately. In the US, foreign residential rental property placed in service after 2017 is depreciated over 30 years under the Alternative Depreciation System (the Tax Cuts and Jobs Act shortened the period from 40 years). This means a 5-million-yen renovation does not give you a 5-million-yen deduction in the year you spend it. It generates roughly 167,000 yen (adjusted to USD) in annual deductions for 30 years. Repairs that maintain existing condition, replacing a broken appliance, repainting, fixing a leaking pipe, are generally expensed in the year incurred. The distinction matters for your tax planning and record-keeping. Keep all renovation invoices organized by category.

Do I need to file a Japanese tax return as a non-resident landlord?

You are not always required to file, but it often makes financial sense. Japan's 20.42% withholding applies to gross rental income. If you file an annual non-resident tax return, you can claim deductions for management fees, repairs, Japanese property taxes, insurance, and depreciation under Japanese rules. In many cases, deductions are significant enough that the tax owed after deductions is considerably less than the amount withheld, resulting in a refund. A Japanese zeirishi (tax accountant) familiar with non-resident rental cases will calculate whether filing is worthwhile in your situation. In most cases I see, it is. The Japanese filing deadline for non-residents is March 15 of the following year, with options to appoint a tax representative in Japan to handle ongoing compliance.

Can my spouse and I own the property jointly to reduce tax exposure?

Joint ownership between spouses is permitted and may offer some advantages in Japan for property tax assessment purposes. On the US side, the implications depend on your filing status and how income and deductions are allocated. Married filing jointly consolidates everything in any case. If you are not married, co-ownership with a non-spouse has different implications: each co-owner files their own FBAR and reports their proportionate share of rental income. Any co-ownership structure should be discussed with your attorney and CPA before purchase, as changing ownership structure after the fact can trigger tax events.

How are Airbnb-style short-term rentals treated differently from long-term leases?

In Japan, short-term vacation rental income (minpaku) and long-term lease income are generally both treated as rental income for tax purposes, but the operational rules differ significantly. Short-term vacation rentals require registration under the Minpaku Law (住宅宿泊事業法), and there are local regulations in ski resort areas that may affect how many nights per year you can rent. Annual limits vary by municipality. For US tax purposes, there are special rules around personal use of vacation homes. If you use the property for personal purposes for more than 14 days or 10% of the rental days (whichever is greater), the IRS may treat it as a personal residence rather than a pure rental property, limiting your ability to claim losses. For vacation home owners who both rent and personally use the property, careful day-counting records are important.

What happens to my Japanese property when I die? How does US estate tax interact with Japanese inheritance tax?

This is one of the most underappreciated risks for American property owners in Japan, and it requires its own conversation with an estate planning attorney familiar with both systems. Japan has one of the highest inheritance tax rates in the developed world, up to 55% on large estates. The US also has an estate tax with a federal exemption (USD 15 million per individual as of 2026, permanently set by the One Big Beautiful Bill Act signed July 4, 2025). For most buyers at the 30 to 80 million yen property level, the US estate tax exemption is unlikely to be an immediate issue, but Japanese inheritance tax absolutely can be. The combination of a Japanese property in a US estate can create complications around valuation, timing, and credit for foreign taxes paid at death. Plan this before you need to.

Working With Me

I have been working in the Nagano mountain valleys for more than a decade, primarily helping international buyers navigate the Japanese property market, from initial search through contract, renovation coordination, and introduction to local management teams. I know the Hakuba and Nozawa Onsen markets specifically, and I understand the particular requirements of buyers who want a property that works for personal ski trips and generates meaningful rental income while they are away.

The US-specific reporting obligations covered in this guide are real, but they are manageable with the right team around you. I can introduce you to bilingual property managers who handle non-resident landlord withholding compliance, Japanese tax accountants familiar with foreign buyers, and judicial scriveners experienced with the FEFTA process. I do not give tax advice and I do not pretend to. That is what your US CPA is for, and finding the right one is genuinely important. But I can help you understand the landscape before you engage professionals, so you are asking the right questions.

If you are looking at properties in the 15 to 60 million yen range with renovation potential, or newer construction in the 40 to 80 million yen range in Hakuba or Nozawa Onsen, I would be glad to share what is currently available and what the realistic rental income projections look like.
