A move out of Japan can become a tax event before you actually sell anything.
But the rule is narrower than the panic version spreading online.
The Japan exit tax rules can treat certain assets as sold when some residents leave the country. The people most exposed are higher-asset residents who hold at least ¥100 million in covered assets and meet Japan’s domestic-residence test. It matters now because many departing residents still think this is a simple “leaving fee,” when official National Tax Agency materials show a more technical system with strict trigger conditions.
According to official NTA guidance, the rule applies to certain residents leaving Japan who hold ¥100 million or more in covered assets and who have, in principle, more than five years of domestic-residence period in the previous 10 years. The covered assets are not all global wealth. The NTA lists securities such as shares and investment trusts, interests in anonymous partnership contracts, unsettled margin transactions, and unsettled derivatives.
Japan Exit Tax Rules: What Changed
The first thing to understand is that this is not a brand-new 2026 tax. Official NTA materials say the exit tax system has applied to certain departures since July 1, 2015. What it does is deem a transfer to have happened at the time of departure, or at the value three months before departure in some pre-departure filing cases.
That means the real shock is not a flat departure fee. It is that unrealized gains on covered assets can be pulled into an income-tax filing even though the person has not actually sold those assets yet. Official materials say affected taxpayers must calculate business income, capital gains, or miscellaneous income, file a return, and pay the tax unless relief procedures apply.
Another detail many residents miss is the five-year test. The NTA FAQ says the domestic-residence calculation has special rules and does not simply mean “five years on any visa.” It says periods spent in Japan under certain Appendix I statuses, including categories such as student, intra-company transferee, and short-term stay, are not counted in that domestic-residence period test.
Who Is Affected
This mainly affects departing residents with large securities-type holdings, not every foreigner moving out of Japan. Official trigger criteria focus on being a resident who is leaving Japan, holding covered assets worth at least ¥100 million, and meeting the domestic-residence period test. Permanent residency status by itself is not listed as the trigger.
In practical terms, the people most likely to need a serious pre-departure review are:
- long-term residents leaving Japan with large stock or fund holdings
- founders, investors, and executives holding appreciated securities
- people with unsettled margin or derivatives positions
- residents who assume bank deposits and everyday cash alone are what matter
- people treating the five-year rule as a simple visa-duration count without checking the official counting method
This is also why the phrase “all global assets” can mislead people. The official NTA asset list is much narrower than that and centers on covered securities and similar financial positions, not every asset a person owns worldwide.
Old Rule vs New Rule
Old assumption:
- you only owed Japanese tax after you actually sold the asset
- leaving Japan itself did not feel like a taxable event
- many residents thought the rule worked like a simple visa or PR issue
Official rule:
- departure can create a deemed sale for certain covered assets
- the asset threshold is ¥100 million in covered assets, not every asset you own
- the residence test is more technical than “five years on any status”
- filing and payment obligations arise unless a relief or deferral procedure is properly used
There is also a second gap between rumor and reality. Official materials describe a tax filing and deemed-transfer system, not a simple flat 15% “exit fee.” The NTA’s public explanations focus on deemed gains, filing, payment, and possible relief, not on a one-line leaving penalty.

What Applicants Should Know Now
If you may be caught by the rule, timing matters. The NTA says people who make the required notification before departure and provide the required collateral can obtain a five-year payment deferral, and in long-term overseas stay cases that deferral can be extended for another five years. Without those procedures, the tax process becomes much less forgiving.
A practical checklist now looks like this:
- check whether your covered assets really cross the ¥100 million threshold
- do not confuse all wealth with the NTA’s covered-asset list
- confirm how your domestic-residence period is counted under the official rules
- speak to a qualified tax professional before departure if you may be close to the threshold
- handle any tax-agent notification and collateral steps before leaving if you need deferral
There are also relief points people overlook. Official NTA materials say tax may be reduced if the asset value later falls, foreign tax credit may apply in some double-taxation cases, and tax imposed under the exit-tax system can be canceled in some cases if the person returns to Japan within the deferral period while still holding the assets.
Official Note
According to the NTA’s 2025 report, Japan actively uses exchange-of-information under tax treaties and the Common Reporting Standard to examine outward investments and overseas transactions. But the NTA’s own CRS overview also says Japanese Individual Number, commonly called My Number, is exempt from reporting in the self-certification for Japan-resident account holders. That means official sources support international information exchange, but not the simplest viral claim that My Number alone instantly maps every overseas account.
The real risk is not just the tax bill. It is misunderstanding how targeted the rule is, assuming it only matters after a sale, or discovering too late that departure paperwork should have been handled before the flight was booked.

Question for readers: If Japan can tax unrealized gains at departure for some residents, does that feel like fair enforcement to you — or an unfair penalty for leaving?
