Naoto Shiraiwa Cuts Stake in Japan Investment Advisor (7172) to 0% | Large Shareholding Report

A large shareholding report (EDINET filing) shows that Naoto Shiraiwa has reduced his stake in Japan Investment Advisor (7172) to 0%. The company is a financial investment firm primarily engaged in operating lease business for aircraft, ships, and containers, while also operating solar power plants and managing private equity investments. Shiraiwa's complete exit represents a reduction of 17.10 percentage points from the previous disclosure, with an estimated sale amount of ¥21.2 billion—a substantial transaction representing a significant portion of the company's market capitalization.

Shiraiwa's full liquidation of his shareholding was disclosed in the amendment report filed on June 15, 2026. This transaction marks the final phase of a gradual stake reduction, completing Shiraiwa's full exit from the position.

*Speculation: The decision to fully divest at a relatively stable share price level suggests the possibility of profit-taking following medium to long-term value appreciation, or a strategic repositioning of his investment portfolio.
