Japan's exit tax, introduced on July 1, 2015, was designed to prevent high-net-worth long-term residents (particularly wealthy foreign executives and entrepreneurs) from relocating to a low-tax jurisdiction immediately before realising large capital gains on financial portfolios. The ¥100 million threshold and 5-year residency requirement mean the exit tax does not affect most foreign employees on temporary assignments in Japan. However, for long-term Japan residents — foreign nationals who have built significant investment portfolios during 10+ years of Japanese residency — the exit tax can be a significant departure cost. Beyond the exit tax, Japan's administrative departure process (Jūminhyo deregistration, final kakutei shinkoku) is well-defined.
Japan-to-USA migration is common among multinationals rotating staff and Japanese-American families. Key JP-US planning points:
Exit tax and US residency timing: Japan's exit tax is assessed on the day before departure. If you depart Japan on March 1 and become a US tax resident on March 1 (same day), there is potential for the gains to be assessed by both Japan (as pre-departure deemed disposal) and the USA (as income from the date of US residency). Work with a cross-border specialist to time the Japanese departure and US residency commencement to avoid double taxation on the same gains.
Japan-USA DTA: The 2003 Japan-USA DTA is comprehensive. Capital gains: primary taxing right generally in residence country. If the exit tax creates a deemed gain while you are still Japan-resident, Japan taxes first; US FTC for Japan taxes paid. Pension: Japan pension payments to US residents — 10% Japanese withholding (DTA Article 17); creditable in USA.
Japanese pension lump sum vs preservation: If you have fewer than 10 years of total Japanese pension contributions but more than 6 months: the lump-sum withdrawal is available (20.42% withholding). Under USA-Japan totalization agreement: US Social Security years + Japanese pension years can be combined to reach the 10-year threshold — this may make keeping the pension worthwhile.
FBAR for Japanese accounts: Once a US resident, all Japanese bank accounts exceeding $10,000 in aggregate must be reported on FinCEN Form 114 annually.
