Frequently asked questions

What is the New NISA?+

It is Japan's tax-free investment account, renewed in 2024. It has an accumulation frame (¥1.2M/year) and a growth frame (¥2.4M/year) — up to ¥3.6M per year and ¥18M over your lifetime — and investment gains stay tax-free indefinitely.

How is the tax benefit calculated?+

A regular taxable account in Japan is taxed about 20.315% on investment gains. This simulator shows that tax — which the New NISA lets you keep — as the tax-free benefit.

Is this investment advice?+

No. It is an estimate based on a constant assumed return and is not investment advice. Real returns vary; make your own decisions.
