A large shareholding report (EDINET filing) shows that Shigeru Masono completely divested his stake in Japan Chemical Industry (4092) to 0%. The company is an established manufacturer of industrial chemicals, with functional materials such as barium titanate for MLCCs representing 52% of sales and inorganic chemicals including chromium compounds (of which it is Japan's sole producer) accounting for 45%, making this a significant shareholding reduction by a major investor through an off-market transaction. Masono, who reported holding 9.98% in July last year, has now exited the company entirely.

Complete Exit Within One Year, Reduction of 9.98 Percentage Points

Masono filed two disclosures on this holding. His initial report dated July 23, 2025 showed a 9.98% stake. Approximately one year later, in his August 4 filing this year, he transferred the entire position, reducing his ownership to zero.

Transfer to Company-Related Party via Off-Market Deal

The recipient was Momoko Maeda, director of Japan Chemical Industry's supplier employee shareholding association. The transaction took place outside the market through direct negotiation, with estimated proceeds of ¥5.01 billion. Notably, Momoko Maeda is now the company's largest shareholder at 10.33%, suggesting that Masono's holding has been consolidated within this key shareholder.

Masono's Former Position Within the Shareholder Base

Following the divestment, the shareholder hierarchy is led by Momoko Maeda at 10.33%, followed by C&I Holdings Co. at 8.91%. Masono's previous holding had substantially exceeded those of Nomura Securities (1.05%) and Nomura Asset Management (1.01%), but his complete exit has eliminated his presence from the register.

Divestment at Elevated Valuation, Corporate Assessment Phase

The stock was trading at ¥5,780 at the time of sale. With a PER of 37.8x representing relatively elevated valuation and a PBR of 1.09x, the shares have been trading near their 52-week highs, at the 96th percentile of the year's range. The full divestment occurred during this period of elevated prices, likely providing Masono with a favorable exit valuation.

*Speculation: The consolidation of all shares into the supplier-affiliated employee shareholding association may signal a shift toward stabilized ownership by management and employee layers.
