Financial independence planning built for Japan.
Model taxes, residence tax, NHI, pensions, 新NISA, iDeCo, household commitments and foreign assets in one Japan-specific scenario.
Retirement timing is not one number.
Your accessible bridge, later pension income, account restrictions, local costs, taxes, insurance and currency assumptions can all arrive on different clocks. JPFIRECalc makes those assumptions visible so you can compare scenarios instead of hiding them in a single rule of thumb.
Japan-specific inputs
- NTA tax and residence-tax assumptions
- NHI and social-insurance estimates
- Public pension timing and estimates
- 新NISA and iDeCo access boundaries
Make uncertainty legible
- Regional spending assumptions
- Foreign assets and currencies
- Returns, inflation and volatility
- Household and education commitments
Use the tool to explore your assumptions.
Separate accessible savings, NISA, iDeCo, cash, foreign assets, spending and pension information.
Choose a region, enter the household budget and record which figures are assumptions rather than facts.
Run downside returns, higher inflation, different spending and later pension scenarios without overwriting the base case.
Build a scenario, then inspect what makes it work.
The calculator is hosted as a standalone application. The embedded view below preserves the full working surface; open it in a new window if you prefer.
