Expat professional
Mid-term resident balancing two countries.
Who this is for
You are settled and working, possibly for a few years, with money and obligations spanning Japan and home.
The basics are handled; now the cross-border questions appear. Should you invest in Japan when you might leave? How do NISA and your home-country accounts interact? What happens to tax when you move on?
Your edge is planning with an exit in mind — using tax-advantaged tools while resident, without creating a mess for the day you leave.
Your money priorities
- Clarify your tax residency status and its five-year milestones
- Decide how NISA/iDeCo fit a possibly temporary stay
- Coordinate accounts and reporting with your home country
- Plan the tax and pension consequences of leaving early
Watch out for
- Leaving Japan changes NISA/iDeCo eligibility — know the rules first
- Japan’s exit tax can apply to large holdings on departure
- Home-country reporting (e.g. US FBAR/FATCA) may still apply
