Hisao Tanaka

This profile gathers the share dealings of Hisao Tanaka across 2 companies, led by ジャパンマテリアル株式会社 and 田中 久男. We count 2 filings; the first trade dates from 7 December 2021 and the latest from 30 May 2025.

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 4 June 2025, the filings show a transaction in ジャパンマテリアル株式会社. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
