How much money do I need to retire in Japan as an American?
Short answer: There is no single figure — the honest answer depends on whether you are in central Tokyo or a smaller city, your visa route, whether you are on Japan's national health insurance, and how your US retirement income is taxed once you are Japan tax resident. The number that matters is not a published average but a plan built from your own spending, visa status and account structure.

Why it works this way
Japan has no dedicated retirement visa in the way some countries do, so most long-term American retirees arrive through a spouse visa, long-term resident status, or other qualifying routes — the visa path affects timelines and, in some cases, tax residence planning.
Japan's National Health Insurance is available to residents and is generally affordable relative to US private coverage, but premiums and the services covered vary by municipality and household income, and should be budgeted alongside any supplemental coverage for visits to the US.
The single biggest planning variable for most American retirees is not daily cost of living but how 401(k)/IRA withdrawals and Social Security are taxed between the two countries, which is why the same nominal income can net very differently depending on how it is drawn.
The expensive mistake: Budgeting Japan living costs without budgeting the tax drag on withdrawals
Tokyo living costs are well documented online; the combined Japan–US tax on the retirement income funding those costs is not, and it is usually the larger number.
What to do
- Confirm your visa route for long-term residence — This shapes both your timeline and tax residence position.
- Model your actual spending in yen — City and regional costs differ substantially; use your target area, not a national average.
- Model the combined tax on your retirement income sources — This usually matters more to the final number than the cost-of-living difference.
