Syoji Tanaka

Syoji Tanaka discloses dealings in 2 companies, chiefly 田中 正治 and ヤスハラケミカル株式会社. Between 16 August 2021 and 16 December 2025, the trades on record add up to 5 filings.

Every open-market trade on record is a purchase: 3 purchases, and no sale. The amount is not disclosed for 3 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

The newest entry dates from 23 December 2025: a transaction, in ヤスハラケミカル株式会社. The clock since the last published purchase (22 October 2021) now reads 1,845 days. Typically, a trade is published a median of 7 days after it takes place. 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.
