Japan Post Holdings Continues Selling Aflac Shares, Shrinking Stake to 51.04%

Japan Post Holdings Co., Ltd. (JPH) Continues Aggressive Selling of Aflac Shares

In its most recent Form 4 filing dated 12 June 2026, Japan Post Holdings Co., Ltd. (JPH) disclosed the sale of 52 400 shares of Aflac Incorporated, representing just under 0.1 % of Aflac’s outstanding equity. The shares were sold through the J&A Alliance Trust at an average price of $117.72 each, reducing JPH’s stake from 51.07 % to 51.04 %. Although the transaction size is modest, it fits into a broader pattern of consistent divestitures that JPH has executed over the last five months.

Market and Investor Implications

Aflac’s share price has experienced a mild up‑trend, rising 1.9 % over the week and 14.8 % year‑to‑date, and approaching its 52‑week high of $119.81. The recent sales by JPH have not generated significant price volatility; market absorption appears calm, as indicated by a near‑zero sentiment score and low media buzz. For long‑term investors, this pattern suggests that JPH is steadily tightening its exposure without signaling a fundamental shift in its view of Aflac’s business model. Aflac’s solid earnings multiple—P/E of 13.4—and diversified product portfolio across the United States and Japan provide a robust income base that can accommodate incremental share repurchases or sales by large holders.

Potential Impact on Aflac’s Future

With JPH still holding a 51 % stake, Aflac remains effectively under Japanese institutional control. The gradual reduction in holdings could signal a rebalancing of the trust’s portfolio, potentially freeing up capital for JPH to deploy in other strategic initiatives or to support its broader pension obligations. A smaller shareholder base may also enhance liquidity and create opportunities for other institutional investors to acquire larger positions. Management has not announced any immediate plans to alter Aflac’s capital structure; therefore, the sale is unlikely to trigger a share repurchase program or dividend increase at this time.

Japan Post Holdings’ Buying–Selling Profile

Since early 2025, JPH has maintained a disciplined “buy‑and‑hold” strategy for Aflac shares, typically purchasing at the lower end of the price range (approximately $110–$115) and subsequently executing incremental sales in the $115–$120 range. The trust structure allows JPH to sustain a long‑term investment stance while managing liquidity risk. In June alone, JPH sold more than 70 000 shares, marking the largest single‑day volume in the past month, yet the cumulative impact on its ownership remains modest—still above 51 %.

Conclusion

For investors, the key takeaway is that Aflac’s strategic direction remains stable, with no immediate catalyst for a significant shift in valuation or dividend policy. Japan Post’s incremental selling is part of a long‑term portfolio strategy rather than a response to short‑term market conditions. As Aflac continues to deliver strong underwriting results, the share price is likely to remain resilient, and the gradual dilution of the trust’s stake may create attractive buying opportunities for value‑seeking investors.
