TOKYO, 23 SEPTEMBER 2026 —
Japanese families can now apply for tax-advantaged Child NISA accounts, with investments set to begin in January 2027, as the government seeks to shift ¥2,386 trillion in household savings—half of which remains in cash and deposits—into long-term capital markets.
Market Impact
The move targets a generational wealth imbalance: elderly households aged 65 and older hold an average of ¥24.9 million in savings, while younger families face rising costs for housing, education, and child-rearing. With food consumption reaching 30.1% of household spending in July 2026—the highest July figure since 2000—younger Japanese struggle to accumulate assets despite growing financial needs.
Modelled on the UK’s Individual Savings Account (ISA), Child NISA allows tax-free investments in equities and mutual funds for children under 18. The policy aims to make investing as intuitive as saving, addressing deep-rooted cultural and economic barriers. Older Japanese prioritise liquidity for longevity risk, while younger generations—44% of whom under 50 already hold NISA accounts—view it as their first meaningful investment vehicle.
The challenge lies in persuading households that investing is secure. Japan’s NISA program, launched in 2014, has seen 20.14 million accounts and ¥11.76 trillion in purchases through July 2026, with 38% allocated to Japanese stocks. But broader adoption hinges on trust: postal savings, once the backbone of household finance, peaked at ¥260 trillion before privatisation, reflecting a generation’s preference for guaranteed returns over market risk.
Child NISA could accelerate wealth transfer earlier in life, complementing similar initiatives in South Korea and Taiwan, where tax incentives and government-funded accounts aim to address ageing populations and low birth rates. South Korea expanded its ISA incentives, while Taiwan’s stalled legislative proposal would mandate universal child accounts with annual government contributions.
For Malaysian investors and policymakers, Japan’s experiment underscores the tension between liquidity and growth in ageing Asian economies. With Malaysia’s own demographic shift—median age rising to 33.3 in 2023 and projected to exceed 40 by 2050—similar mechanisms could emerge to redirect savings into productive assets before inheritance becomes the sole wealth-transfer method. The success of Child NISA will depend on whether it bridges the gap between risk aversion and long-term financial security for future generations.
