Seika Corporation

Seika Corporation is a declared insider at 3 companies; the most frequent names are 東京産業株式会社, 日本フェンオール株式会社 and 株式会社TVE. Between 13 March 2023 and 29 September 2026, the trades on record add up to 7 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The newest entry dates from 6 October 2026: a transaction, in 東京産業株式会社. Typically, a trade is published a median of 7 days after it takes place. This delay matters because a trade only becomes useful information once it is public. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
