The Financial Services Agency said on 2 October that Japan had 30,480,850 NISA accounts at the end of June 2026. Its transition table puts the end-2025 total at 28,206,434, and the survey sheet shows an 8.1% rise from its year-end comparison figure. Cumulative NISA purchases stood at ¥85tn. The government's targets for end-December 2027 are 34 million accounts and ¥56tn of purchases, so buying has already passed its goal while account numbers have not reached theirs.
What the ¥85tn measures
The figure is cumulative purchases since 2014, not assets. For the current system it includes purchases under the older general NISA and the accumulation NISA (tsumitate), and the FSA's transition table puts the total at ¥71.4tn at end-2025. The same table shows a NISA balance of ¥36.8tn at end-2025 and gives no balance for end-June. The headline total therefore says nothing about net flows or what investors hold today.
What investors bought in 2026
Purchases made within the 2026 allowance totalled ¥13.82tn by end-June: ¥10.16tn in the growth investment allowance and ¥3.66tn in the accumulation investment allowance. Amounts are valued at market price on the purchase date.
| Product | Purchases | Share of total |
|---|---|---|
| Investment trusts | ¥8.56tn | 61.9% |
| Listed stocks | ¥4.76tn | 34.5% |
| ETFs | ¥457bn | 3.3% |
| REITs | ¥41.6bn | 0.3% |
Investment trusts took 61.9% of the total and listed stocks 34.5%. The growth allowance was close to an even split, with trusts at 48.4% and listed stocks at 46.9%. The accumulation allowance was almost entirely funds: designated index trusts took 88.1% (¥3.23tn) and actively managed and other public equity trusts 4.9% (¥179bn). The FSA says the product split does not add up to the total there because some surveyed institutions could not supply product-level data. The tables do not split purchases between domestic and overseas assets.
Who is opening and buying
Accounts held by people in their teens numbered 490,730, or 1.6% of the total. Savers in their 50s hold the most accounts, 5,999,082 or 19.7% of the total. By purchases, the 50s lead with 23.0%, followed by the 40s at 20.5% and the 60s at 18.4%. Those in their 20s hold 12.4% of accounts but made 6.6% of purchases.
The survey covered 702 institutions offering the growth allowance and 678 offering the accumulation allowance. The FSA notes that percentage shares may not sum to 100% because of rounding.
