Tax residency and wealth structuring for new Japan residents

Tax residency and wealth structuring for new Japan residents Japan’s tax system for new residents contains a specific asymmetry that most advisors understate: the country taxes all residents on their worldwide income, but it carves out a five-year window during which foreign-source capital gains and certain passive income streams are shielded from domestic taxation, provided the funds never enter Japan. This window, defined under Article 7 of the Income Tax Law (Shotokuzei-hō), applies only to individuals classified as “non-permanent residents” — a status that expires after five years of cumulative residence in any ten-year period. For a high-net-worth individual moving to Tokyo or Osaka in 2026, the difference between arriving with a pre-migration trust structure and arriving without one can exceed several hundred thousand dollars in annual tax exposure, depending on portfolio composition and exit-timing of foreign assets. The following sections map the statutory framework, the timing traps, and the structuring steps that produce materially different outcomes. ## The residency test and its three categories Japan does not use a simple 183-day rule. The Immigration Control and Refugee Recognition Act (Nyūkan-hō) determines legal residence status, while the Income Tax Law assigns one of three taxpayer categories based on intent, duration, and physical presence. The category determines which income streams Japan can tax. ### Non-resident classification An individual who has not established a domicile (jūsho) in Japan and has not resided there for one year or more is classified as a non-resident. Non-residents are taxed only on Japan-source income — employment performed inside Japan, real estate located in Japan, and business carried on through a Japanese permanent establishment. Foreign-source capital gains, dividends, and interest are entirely outside the tax net. This classification is the most favourable for wealth preservation but is difficult to maintain once a principal establishes a home, registers a vehicle, or enrols children in Japanese schools. ### Non-permanent resident classification This is the category that matters most for new arrivals. A non-permanent resident is defined under Article 2(1)(iii) of the Income Tax Law as an individual who has a domicile in Japan but has not had a domicile in Japan for more than five years during the preceding ten years. For such individuals, Japan taxes all Japan-source income and all foreign-source income that is remitted into Japan, but it does not tax foreign-source income that is earned and held outside Japan. The five-year clock begins on the date the individual establishes a jūsho — typically the date of arrival with intent to reside. The National Tax Agency (NTA) interprets “remittance” broadly to include any transfer of funds into a Japanese bank account, any repayment of a loan from a Japanese entity, and any use of a credit card issued in Japan to pay for goods or services abroad. ### Permanent resident classification Once cumulative residence exceeds five years, or once the individual demonstrates intent to reside indefinitely (for example, by acquiring permanent residence status or holding a spouse visa with no fixed departure date), the NTA reclassifies the individual as a permanent resident. At that point, worldwide income — including foreign-source capital gains, dividends, rental income, and interest — becomes fully taxable in Japan, regardless of whether the funds are remitted. The only relief is the foreign tax credit mechanism under Article 95 of the Income Tax Law, which offsets Japanese tax liability by the amount of foreign tax paid on the same income, subject to a per-country limitation. ## Source versus worldwide income: what is actually at stake The distinction between Japan-source and foreign-source income determines the scope of taxation during the non-permanent resident window. The NTA’s administrative guidelines (Kankei Tsūtatsu) provide detailed classification rules, and the differences are not always intuitive. ### Japan-source income for new residents Employment income for work performed inside Japan is Japan-source, regardless of the employer’s location. A Singapore-based fund manager who relocates to Tokyo and continues to manage the same fund will have her salary treated as Japan-source from day one. Similarly, income from real estate located in Japan, dividends from Japanese corporations, and interest on Japanese bank deposits are Japan-source. Capital gains on the sale of shares in a Japanese company are Japan-source if the shares are listed on a Japanese exchange or if the company’s principal assets are Japanese real estate. ### Foreign-source income during the five-year window Foreign-source income includes capital gains on the sale of non-Japanese securities, dividends from non-Japanese corporations, interest on non-Japanese bank accounts, rental income from non-Japanese real estate, and business income from a foreign enterprise without a Japanese permanent establishment. During the non-permanent resident period, none of this income is taxed in Japan so long as it is not remitted. The NTA’s 2022 circular on remittance rules (Kokuzei-kyoku Tōtatsu No. 2022-1) clarified that a remittance occurs when funds are transferred into a Japanese account, but also when a Japanese credit card is used to pay for a foreign expense and the card is settled from a foreign account. The circular further stated that a loan guarantee provided by a Japanese resident to a foreign entity can trigger a deemed remittance if the guarantee is called. ### The five-year trap and the ten-year lookback The five-year period is not reset by leaving Japan for a short trip. If an individual departs Japan after three years and returns two years later, the cumulative residence clock continues from where it left off. The ten-year lookback means that any prior residence in Japan counts toward the five-year ceiling. A principal who lived in Tokyo for four years between 2018 and 2022 and returns in 2026 will have only one year of non-permanent resident status remaining before becoming a permanent resident for tax purposes. The NTA’s 2019 ruling on cumulative residence (Saiban-rei Heisei 31-nen) confirmed that temporary absences of fewer than 183 days per year do not break the continuity of residence. ## Capital gains treatment and the remittance trap Capital gains are the single largest exposure for most high-net-worth new residents, and Japan’s treatment differs materially from that of Hong Kong, Singapore, or the United Arab Emirates. ### Gains on foreign securities A non-permanent resident who sells shares in a US-listed technology company while living in Tokyo owes no Japanese tax on the gain, provided the sale proceeds remain in a US brokerage account and are not used to fund Japanese living expenses. The moment the proceeds are transferred to a Japanese bank account, the gain becomes taxable in Japan at the flat rate of 20.315 per cent (15 per cent national income tax, 5 per cent local inhabitant tax, and 0.315 per cent special reconstruction surtax under the Act on Special Measures for Reconstruction, Law No. 13 of 2011). This rate applies to both short-term and long-term capital gains; Japan does not distinguish between the two for listed securities. ### Gains on Japanese real estate Gains on the sale of Japanese real estate are always Japan-source and are taxed at progressive rates of up to 45 per cent for short-term holdings (five years or less) and 20.315 per cent for long-term holdings. A new resident who purchases a Tokyo apartment before arrival and sells it during the non-permanent resident window will owe Japanese tax on the gain regardless of whether the proceeds are remitted. The NTA’s 2020 guideline on real estate gains (Kokuzei-kyoku Shishin Reiwa 2-nen) confirmed that the source of the gain is the location of the asset, not the residence of the seller. ### The remittance ordering rule When a non-permanent resident holds multiple foreign accounts and remits funds, the NTA applies a “first-in, first-out” ordering rule. Funds remitted are deemed to come first from foreign-source income earned during the current year, then from foreign-source income earned in prior years, and finally from principal. This means that a remittance of JPY 10 million from a US brokerage account that contains both capital gains and original principal will be treated as a remittance of gains first, triggering immediate tax. The only way to avoid this ordering rule is to maintain a separate account that holds only principal and never commingles gains with principal — a strategy that requires documentation of the cost basis at the time of arrival. ## Structuring steps before arrival The period between the decision to relocate and the actual establishment of Japanese domicile is the only window during which a principal can materially alter the tax outcome. Once the jūsho is established, the scope for restructuring narrows sharply. ### Realising gains before establishing domicile A principal who sells a concentrated equity position while still a non-resident of Japan owes no Japanese tax on the gain, regardless of when the sale proceeds are later remitted. The NTA’s position, confirmed in administrative ruling No. 2008-3, is that the timing of the gain is determined by the date of the sale, not the date of remittance. Selling before the date of arrival — and documenting the trade confirmation with a time stamp — locks in a tax-free outcome for that gain. For a portfolio with unrealised gains of USD 5 million, the Japanese tax saved by selling before arrival is approximately USD 1.02 million at the 20.315 per cent rate. ### Establishing a foreign trust or holding company A non-grantor trust established in a jurisdiction with a favourable tax treaty with Japan (such as Singapore or the United Kingdom) can hold foreign assets and accumulate income outside Japan’s tax net, even after the principal becomes a permanent resident. Japan taxes trust income only if the trust is treated as a grantor trust under Japanese law — which occurs when the grantor retains the power to revoke the trust or to direct the distribution of income. An irrevocable, non-grantor trust with an independent trustee and no power reserved to the grantor is recognised as a separate taxpayer under Japanese trust law (Shintaku-hō, Law No. 108 of 2006). The trust’s foreign-source income is not attributed to the Japanese resident beneficiary until it is distributed, and if the trust is structured to accumulate income, the deferral can last indefinitely. ### Using a family office structure in a low-tax jurisdiction A family office incorporated in Singapore or Dubai that manages the principal’s global portfolio and charges a management fee can shift the source of investment income from Japan to the foreign jurisdiction. The key requirement under Japanese tax law is that the family office must have substance — real employees, a physical office, and independent decision-making authority. The NTA’s 2021 transfer-pricing guideline (Kokuzei-kyoku Kanzei Tōtatsu Reiwa 3-nen) states that a foreign entity with no real economic activity will be ignored for tax purposes, and its income will be attributed directly to the Japanese resident owner. A properly capitalised family office with a licensed fund manager and a board that meets regularly in the foreign jurisdiction can survive an NTA audit. ## The highly skilled professional visa and its tax implications Japan’s Highly Skilled Professional (HSP) visa, administered by the Immigration Services Agency (ISA) under the Immigration Control and Refugee Recognition Act, offers a fast track to permanent residence — typically in one year for those scoring 80 points or more on the HSP point system. The visa itself does not change the tax classification, but the accelerated permanent residence timeline does. ### The one-year permanent residence path An HSP visa holder who scores 80 points can apply for permanent residence after one year of residence in Japan. Once permanent residence is granted, the individual becomes a permanent resident for tax purposes immediately, losing the non-permanent resident status and the associated five-year window for foreign-source income exemption. For a principal with significant foreign assets, the acceleration from five years to one year can increase Japanese tax liability by hundreds of thousands of dollars per year in forgone exemption. ### The trade-off between visa speed and tax deferral A principal who qualifies for the HSP visa must decide whether to apply for permanent residence early or to remain on the HSP visa for the full five-year non-permanent resident window. The ISA’s 2023 statistics show that approximately 70 per cent of HSP visa holders apply for permanent residence within two years, likely unaware of the tax consequences. The correct strategy depends on the size of foreign assets relative to Japanese income. For a principal with JPY 50 million in annual Japanese employment income and JPY 200 million in annual foreign capital gains, deferring permanent residence for five years preserves approximately JPY 40 million in Japanese tax at the 20.315 per cent rate. ## Pre-arrangement of banking and brokerage accounts The remittance rules create a powerful incentive to segregate funds by jurisdiction and by character before arrival. The NTA’s enforcement guidelines require taxpayers to maintain records of the source of each remittance, and the burden of proof falls on the taxpayer. ### Segregating principal from gains A principal who opens a Japanese bank account after arrival and transfers JPY 100 million from a foreign account that contains both original principal and accumulated gains will be deemed to have remitted gains first. The solution is to open a foreign brokerage account before arrival, deposit only principal into that account, and maintain a separate foreign account for gains. The NTA’s 2018 administrative circular on record-keeping (Kokuzei-kyoku Tōtatsu Heisei 30-nen) stated that a taxpayer who can produce a bank statement showing the opening balance and the date of each deposit will be entitled to treat remittances as principal until the principal is exhausted. ### Using a Japanese securities account for Japan-source assets A principal who plans to trade Japanese securities should open a Japanese securities account and keep all Japan-source assets in that account. Gains on Japanese securities are always Japan-source and are taxable regardless of remittance, so there is no advantage to holding them offshore. The Japanese securities account also simplifies tax reporting, because the broker will issue a withholding tax certificate (Gensen Chōshū Hyō) that the NTA accepts as conclusive evidence of tax paid. ### The credit card trap Using a Japanese credit card to pay for a foreign expense — such as a hotel in Singapore or a school fee in Switzerland — triggers a deemed remittance of foreign-source income equal to the amount of the expense. The NTA’s 2022 circular on deemed remittances (Kokuzei-kyoku Tōtatsu Reiwa 4-nen) explicitly stated that a credit card transaction settled from a Japanese bank account constitutes a remittance of foreign-source income if the cardholder has any foreign-source income in the same tax year. The practical solution is to use a foreign credit card for foreign expenses and a Japanese credit card only for Japanese expenses, and to settle each card from an account in the same jurisdiction. ## Inheritance and gift tax considerations Japan imposes one of the highest inheritance tax rates in the OECD — a top marginal rate of 55 per cent on estates exceeding JPY 600 million (approximately USD 4 million), under the Inheritance Tax Law (Sōzokuzei-hō). For new residents, the jurisdictional scope of this tax depends on the length of residence. ### The ten-year rule for inheritance tax Under Article 1-2 of the Inheritance Tax Law, a person who has had a domicile in Japan for ten years or more within the fifteen years preceding the inheritance is subject to Japanese inheritance tax on worldwide assets. A person with fewer than ten years of residence in the preceding fifteen years is subject to tax only on assets located in Japan. This means that a principal who relocates to Japan at age 50 and dies at age 58 will have only eight years of residence, and her non-Japanese assets — foreign real estate, foreign brokerage accounts, offshore trusts — will be outside the Japanese inheritance tax net. ### Gift tax on transfers during life Japan’s gift tax (Zōyo-zei) follows the same jurisdictional rules as inheritance tax. A gift of foreign assets from a Japanese resident to a non-resident family member is taxable in Japan if the donor has been resident for ten years or more in the preceding fifteen years. For a principal who plans to make substantial gifts to children or a spouse, the optimal timing is either before establishing Japanese domicile or during the first nine years of residence, before the ten-year threshold is crossed. ## Exit tax for high-net-worth individuals Japan imposes an exit tax (kessan-zei) under Article 60-2 of the Income Tax Law on individuals who hold JPY 100 million or more in specified financial assets and who relinquish Japanese residence after having been resident for five of the preceding ten years. The exit tax treats all unrealised gains on those assets as deemed realised on the date of departure, and the tax is due immediately. ### The JPY 100 million threshold The threshold includes listed securities, unlisted shares, derivatives, and certain trust interests. Real estate is excluded, but cash and bank deposits are included if they exceed the threshold. The NTA’s 2023 enforcement order (Kokuzei-kyoku Shikō-rei Reiwa 5-nen) clarified that the threshold is calculated at fair market value on the date of departure, and that assets held jointly with a spouse are attributed to each owner proportionally. ### Planning around the exit tax The exit tax applies only to assets that have appreciated in value. A principal who sells all appreciated assets before departure and repurchases them after departure resets the cost basis and eliminates the exit tax exposure. Alternatively, a principal who holds assets through a foreign trust or corporation that is not treated as a pass-through entity under Japanese law may avoid the exit tax, because the tax applies only to assets held directly by the individual. ## Actionable takeaways 1. Sell all concentrated equity positions with significant unrealised gains before establishing Japanese domicile, and document the trade confirmations with timestamps to lock in tax-free treatment under the NTA’s administrative ruling No. 2008-3. 2. Open a separate foreign brokerage account funded solely with principal before arrival, and never commingle gains with principal in that account, to preserve the ability to remit principal tax-free under the NTA’s 2018 record-keeping circular. 3. Defer application for permanent residence under the HSP visa for the full five-year non-permanent resident window if foreign-source capital gains exceed JPY 50 million annually, because the accelerated permanent residence path eliminates the foreign-source income exemption. 4. Establish an irrevocable non-grantor trust in Singapore or the United Kingdom before arrival to hold foreign assets, with an independent trustee and no power reserved to the grantor, to defer Japanese tax on accumulated trust income indefinitely under the Shintaku-hō. 5. Use a foreign credit card for all foreign expenses and a Japanese credit card only for Japanese expenses, settling each card from an account in the same jurisdiction, to avoid deemed remittances under the NTA’s 2022 circular on credit card transactions. 6. Monitor the ten-year inheritance tax threshold by maintaining a calendar of cumulative residence days, and complete any planned gifts of foreign assets to non-resident family members before the tenth anniversary of establishing Japanese domicile. ## Sources - Income Tax Law (Shotokuzei-hō), Article 7 (non-permanent resident definition) and Article 60-2 (exit tax) - Inheritance Tax Law (Sōzokuzei-hō), Article 1-2 (jurisdictional scope) - National Tax Agency administrative ruling No. 2008-3 (timing of capital gains for non-residents) - National Tax Agency circular on remittance rules, Kokuzei-kyoku Tōtatsu No. 2022-1 - National Tax Agency guideline on real estate gains, Kokuzei-kyoku Shishin Reiwa 2-nen - National Tax Agency transfer-pricing guideline, Kokuzei-kyoku Kanzei Tōtatsu Reiwa 3-nen - National Tax Agency record-keeping circular, Kokuzei-kyoku Tōtatsu Heisei 30-nen - National Tax Agency circular on deemed remittances, Kokuzei-kyoku Tōtatsu Reiwa 4-nen - National Tax Agency enforcement order on exit tax, Kokuzei-kyoku Shikō-rei Reiwa 5-nen - Immigration Services Agency, Highly Skilled Professional visa point system, [moj.go.jp/isa](https://www.moj.go.jp/isa/)
