Yasumitsu Shigeta

Yasumitsu Shigeta, listed as major shareholder, appears in our data through filings on 株式会社光通信 shares, published by EDINET (Japan FSA). We count 6 filings; the first trade dates from 22 March 2023 and the latest from 13 March 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 19 March 2026, the filings show a transaction in 株式会社光通信. Filings reach the EDINET (Japan FSA) feed a median of 6 days after the trade. That lag is the time during which only the insider knows about the trade. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
