Meaning

Japan's tax-free investment account system, similar to a British ISA or American Roth IRA.

The 2024 'New NISA' expansion became a cultural phenomenon, sparking nationwide investment interest among people who had never touched stocks before. It dominates financial discussions on social media, with endless content about optimal strategies, and has become shorthand for 'getting started with investing.'
