Daiichi Shokusan Co.

Daiichi Shokusan Co. (chief executive) discloses dealings in 戸田建設株式会社 to EDINET (Japan FSA). Between 21 February 2023 and 1 May 2026, the trades on record add up to 4 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

Most recently, on 13 May 2026, the filings show a transaction in 戸田建設株式会社. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 1 day. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
