Yuuichiro Kosakai

This profile gathers the share dealings of Yuuichiro Kosakai across 2 companies, led by 滝沢ハム株式会社 and 小堺裕一郎. Between 8 July 2021 and 16 January 2026, the trades on record add up to 3 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 21 January 2026, the filings show a transaction in 滝沢ハム株式会社. Filings reach the EDINET (Japan FSA) feed a median of 1 day after the trade. 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.
