NISA

An abbreviation for the Nippon Individual Savings Account, a tax-advantaged investment system unique to Japan where investment gains (dividends and capital gains) from stocks and mutual funds are tax-exempt. The system was significantly expanded in 2024, relaunching as the "New NISA" with an annual investment limit of 3.6 million yen and a lifetime limit of 18 million yen.

Overview of the New NISA and Changes from the Previous System

The New NISA, which launched in January 2024, allows simultaneous use of two investment categories: the Tsumitate (regular investment) category (1.2 million yen annually) and the Growth Investment category (2.4 million yen annually). Under the previous system, investors had to choose between "Tsumitate NISA" and "General NISA," but the new system allows both to be used concurrently. The tax-exempt holding period has been made indefinite, enabling long-term tax-free investing within the lifetime limit of 18 million yen (of which up to 12 million yen can be in the Growth Investment category).

Products eligible for the Tsumitate category are limited to mutual funds and ETFs that meet criteria set by Japan's Financial Services Agency. Since these are selected for low management fees and suitability for long-term, regular, diversified investing, the burden of product selection is reduced for beginning investors. The Growth Investment category covers listed stocks and a broader range of mutual funds, enabling more aggressive investment strategies.

Practical Strategies for Maximizing NISA Benefits

The greatest advantage of NISA is the tax exemption on investment gains. Normally, investment profits are taxed at approximately 20%, but gains within a NISA account are entirely tax-free. If you earn 1 million yen in profit, a regular account would deduct roughly 200,000 yen in taxes, while a NISA account lets you keep the full 1 million yen. This difference grows larger with longer investment horizons.

As a practical strategy, the standard approach is to use the Tsumitate category for monthly fixed-amount investments in a global equity index fund or an S&P 500 tracking fund. The Growth Investment category can be used for individual stock investments or mutual funds not eligible for the Tsumitate category. Filling the lifetime limit of 18 million yen at the maximum annual pace of 3.6 million yen takes 5 years, but there is no need to rush. The most important thing is to continue investing at a pace that matches your income and expense balance without overextending yourself.
