Filings by Hirota.co.ltd span 2 companies, the busiest being ヒロタ株式会社 and 株式会社電算システムホールディングス. In total, 4 filings cover trades dated from 1 July 2021 to 26 December 2025.

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 16 January 2026, the filings show a transaction in 株式会社電算システムホールディングス. Filings reach the EDINET (Japan FSA) feed a median of 15 days after the trade. Until a filing is published, the market cannot know about the trade. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
