What is NISA Tsumitate
NISA Tsumitate (つみたて投資枠) is the installment investment frame of Japan's Nippon Individual Savings Account — a tax-free investment program run by the Financial Services Agency. Under the New NISA system that launched in January 2024, residents of Japan (including foreigners with a My Number) can invest up to ¥1.2 million per year in eligible low-cost index mutual funds and ETFs, with all capital gains and dividends completely tax-free. Last updated: April 2026.
The Tsumitate frame is designed for long-term, dollar-cost-averaged investing. Funds eligible for Tsumitate are pre-vetted by the FSA and limited to broadly diversified, low-fee products — mostly index funds tracking global or developed-market equities. This simulator helps English-speaking residents project how monthly yen contributions compound over decades under realistic return assumptions.
2024 New NISA Rules
The New NISA (新NISA) replaced the old system in 2024 with far more generous limits. The Tsumitate frame allows ¥1.2 million per year (¥100,000 per month), and the Growth frame (成長投資枠) allows a separate ¥2.4 million per year for individual stocks, ETFs, and actively-managed funds. Both frames share a combined lifetime principal cap of ¥18 million per person. Unlike the old system, the tax-free period is now permanent — there is no rollover deadline, and sold principal can be reused the following year.
Tsumitate vs Growth Frame
Tsumitate suits beginners and passive investors: automated monthly debits from a bank account, a curated universe of low-fee index funds, and no timing decisions. Growth frame suits investors who want individual Japanese or US stocks, sector ETFs, or higher-risk active funds. Most English-speaking residents start with Tsumitate only — a ¥30,000–¥100,000 monthly auto-debit into an all-country equity index fund through Rakuten Securities or SBI Securities. You can use both frames simultaneously, up to the ¥3.6M combined annual limit and ¥18M lifetime cap.
Tax-Free Until Withdrawal and Beyond
Inside a NISA account, you pay zero tax on dividends, zero tax on capital gains, and zero tax on fund reinvestment. A taxable brokerage account would take roughly 20.315% of your gains. Over 20 years at 5% annual return, that tax drag compounds dramatically — a ¥30,000/month investor keeps roughly ¥2–3 million more in NISA than in a taxable account. When you withdraw, there is no tax event and no required reporting. Non-permanent residents should confirm their home-country tax treatment, as NISA's tax exemption only covers Japanese tax.
