Sansan has finished the share buyback it approved on May 19, and the programme ended with spending just below its cash cap while remaining below its share cap. Under the board resolution, Sansan was authorized to repurchase up to 2,000,000 shares, equivalent to 1.58% of issued shares excluding treasury stock, for up to ¥2.00bn. The cumulative result was 1,331,600 shares bought for ¥2.00bn, and the company said the programme is now over, even though the original purchase window had run to June 30.

The final stretch was concentrated in June. Sansan said it bought 811,600 shares for ¥1.26bn between June 1 and June 18, using market purchases on the Tokyo Stock Exchange under a discretionary trading mandate. That leaves a simple read of the mechanics: the cash ceiling was nearly used up, while the share ceiling was not.
A separate large-shareholding report filed on June 19 adds the ownership angle. Ichigo Asset Management International, together with Ichigo Asset Management, Ltd., reported a joint holding of 14,666,900 Sansan shares, equal to 11.57%, up from 10.44% in the previous report. The filing's base date was June 12, and it described the holding purpose as pure investment.
The EDINET filing also shows the position was not built only through small market purchases. It lists a series of market acquisitions from April to June, plus an off-market acquisition of 5,599,400 shares on May 13 at ¥1,252 per share.
What the disclosures do not do is connect those two developments. Sansan's buyback notice does not describe the repurchases as linked to any specific shareholder transaction, and Ichigo's holding-change report does not say its increase was tied to the company repurchase. The filing-backed conclusion is narrower but still useful: Sansan has completed a near-full ¥2bn capital return, and a major investor's joint stake stood at 11.57% by mid-June.
