Akira Hayama

Akira Hayama is a declared insider of 理想科学工業株式会社 (major shareholder), with filings sourced from EDINET (Japan FSA). Over a trading history stretching from 10 November 2022 to 3 January 2026, the count stands at 4 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

Most recently, on 8 January 2026, the filings show a transaction in 理想科学工業株式会社. Filings reach the EDINET (Japan FSA) feed a median of 9 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
