Japan Exit Tax (Shukkokuzei) for Departing High-Asset Residents
The Japan exit tax treats covered securities as sold on departure day when a long-term resident leaves with large holdings. Anyone departing Japan with covered assets worth 100M JPY or more after more than five years of presence in the past ten faces deemed disposition of the unrealized gains.12
Procedures, fees, and requirements can change. Confirm current details at the National Tax Agency exit-tax pages. This article is general information, not legal, tax, or immigration advice; for your specific case, consult a licensed zeirishi (tax accountant) and a licensed cross-border tax advisor before departure.
Overview
The regime dates to the 2015 tax reform and applies to departures on or after July 1, 2015.12 Its common name is 出国税 (shukkokuzei, "exit tax"), and the statutory name is 国外転出時課税 (kokugai tenshutsu-ji kazei, "taxation at time of departure").12
Departure means ceasing to hold both domicile and residence in Japan.1 This article describes the statute only. It gives no planning advice beyond the statutory mechanics.
The two gates
Both gates must hold for the charge to apply. Miss either one and the regime does not reach the departure.12
Residence history over five years in ten
The residence gate is aggregate domicile-or-residence presence exceeding five years within the ten years before departure.12 Presence is cumulative, not continuous, so spaced assignments add together.
Periods under Immigration Control Act Table 1 statuses are excluded from the count. That carve-out covers Student, Cultural Activities, and certain Designated Activities stays, among the listed Table 1 categories.2 Holders of permanent residency, long-term-resident status, and work statuses count their periods normally.2
Covered assets at or above 100 million yen
The asset gate is total covered-asset value of 100M JPY or more at the relevant time.12 Covered assets are securities and similar instruments, unsettled margin positions, and unsettled derivatives.12
Valuation follows the departure date for post-departure filers, or the date three months before the scheduled departure for pre-departure filers.2 Cash and Japan or overseas real estate are not covered assets and do not count toward the gate.34
| Gate | Test | Outcome if missed |
|---|---|---|
| Residence | Presence over five years in the past ten, Table 1 periods excluded | Regime does not apply2 |
| Assets | Covered assets at 100M JPY or more at the relevant date | Regime does not apply1 |
The table states the two gates. The 100M JPY figure decides coverage; the tax itself falls only on unrealized gains, covered next.12
The deemed-disposition mechanic
Deemed disposition treats covered assets as transferred or settled at departure value without any actual sale. The resulting gains enter business, transfer, or miscellaneous income and are reported on the departure return.12
The chart shows the departure flow. Each step below follows the National Tax Agency FAQ sequence.2
Valuation and gain timing
Gains are departure-date value minus cost basis per asset, aggregated across the covered pool.2 The departure return carries the computation, and the tax agent (納税管理人, nōzei kanrinin, "tax agent for departure procedures") handles post-departure compliance where the taxpayer has already left.2
Gift and inheritance transfers to non-residents
Gifts, inheritances, and bequests of covered assets to non-residents trigger parallel deemed-disposition charges without any departure.1 The transferor side faces the gain computation at the transfer time under the companion provisions.1
Exemptions and deferral
The statute pairs narrow exemptions with a collateralized deferral path. Both are procedural and document-heavy, so start them before departure day.23
Visa-status exemptions
Student, Cultural Activities, and certain Designated Activities periods are excluded from the five-year count.2 A researcher who spent four years as a student and three as a worker counts only the three work years and falls outside the regime.
The exemption turns on status history, not nationality. Foreign executives on work statuses receive no blanket pass, while students of any nationality benefit from the carve-out.24
Deferral with a tax agent and collateral
Appointing a nōzei kanrinin, posting collateral equal to the deferred amount, and filing for deferral by the deadline suspends payment for five years from departure.253 A prescribed extension filing before the five years expire adds five more years, for ten total.23
Annual asset-status reports keep the suspension alive. Returning to Japan and still holding the assets within the window allows cancellation of the charge through prescribed procedures.23 Where asset value has fallen by the end of the deferral period, a recomputation at the lower value is available by amended claim within four months.2
Good to know
The threshold counts value, the tax counts gains
Coverage turns on 100M JPY of covered-asset value at the relevant date. The taxable base is unrealized gains only, so near-threshold portfolios need evidence-based valuation with exchange-rate and private-company detail rather than rough estimates.14
Departure paperwork and the tax agent appointment
The final return, the tax-agent notification, and any deferral election form one sequence with the ward-office and immigration steps. Coordinate the tax calendar with the move calendar rather than treating them as separate tracks.2
US persons still face the US side
The savings clause preserves US taxation of citizens, so Japan-side deferral or cancellation does not settle the US position. US persons confirm the destination-country credit interaction with the cross-border advisor rather than assuming treaty relief.6
