Hitoshi Nakauchi

All filings by Hitoshi Nakauchi on record concern コロンビア・ワークス株式会社. Between 27 March 2024 and 30 June 2026, the trades on record add up to 5 filings.

Not one of the filings records a straightforward purchase or sale on the market. 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 7 July 2026, the filings show a transaction in コロンビア・ワークス株式会社. Filings reach the EDINET (Japan FSA) feed a median of 7 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
