Leaving Japan: What to Know
Tax Departure Rules for Japan
Japan imposes an exit tax (kokugai tenkin-zei) on unrealised gains exceeding ¥100 million in financial assets when a tax resident who has lived in Japan for 5 of the last 10 years departs. This was introduced in 2015 to prevent high-net-worth individuals from moving assets offshore tax-free.
Capital gains considerations: Japan taxes capital gains at approximately 20.315% (15.315% national + 5% resident). The exit tax only applies to financial assets exceeding ¥100 million. Real estate gains have separate rates depending on holding period (short-term: ~39%, long-term: ~20%).
Practical steps when leaving: Submit a moving-out notification (tenshutsu todoke) at your local ward office, file a final tax return or appoint a tax representative (nozei kanrinin), and close or restructure Japanese financial accounts. National Health Insurance ends upon deregistration.
