Japan NISA system: Inheritance tax rules and financial education for minors

Japan's NISA (Nippon Individual Savings Account) system presents specific tax implications for inheritance and long-term financial planning for minors.

Regarding inheritance, NISA accounts themselves cannot be passed down to heirs. When a holder dies, the financial assets within the NISA must be transferred to the heir's taxable or general account. While the assets are subject to inheritance tax based on their value at the time of death, dividends earned after the transfer are subject to standard taxation (approximately 20%) rather than the tax-exempt status of the original NISA account.

For younger investors, the upcoming 'Kodomo NISA' (starting in 2027) will allow individuals aged 0–17 to utilize a tax-exempt investment quota for long-term, diversified index funds. To supplement this, parents can use minor accounts to purchase single shares (unit-less shares) of individual companies. This approach is suggested as a method for practical financial education, allowing children to learn about corporate ownership through familiar brands.
