Key Points
- Week 4 of June 2026: individuals' two-market weekly net buy hit ¥950.4B, beating the April-2024 record of ¥908.6B — an all-time high
- Gross weekly buying reached ¥20.2T, surpassing the ¥19.2T record set just one week earlier
- Driver: new NISA channels Japan's long-idle household savings into equities, forming a steady bid
- Risk: retail buying high and highly one-directional — if foreign selling persists and indices fall, late buyers face pressure
Analysis
Foreigners are dumping, but Japanese retail is buying like never before. JPX's investor-type record file shows that in week 4 of June 2026, individual investors' weekly net buying on the two markets (TSE + Nagoya) hit ¥950.4B — a new all-time record, topping the mark set in April 2024. Their gross weekly buying also soared to ¥20.2T, another record. Two record-breaking charts show where Japanese household money is heading.
