The Japan Financial Services Agency has published an overview of preliminary results from its NISA Account Usage Survey, providing an update on the number of NISA accounts and purchase amounts held within NISA accounts. The survey covers all financial institutions that handle NISA and reports figures as of end-December 2025 on (i) the number of NISA accounts and (ii) purchase amounts in NISA accounts. The release also includes trend materials showing changes in NISA usage since the system began in 2014. The agency noted that the figures are preliminary and may differ from a confirmed NISA Usage Survey to be released in the future.
