Suiko Tsukamoto

Suiko Tsukamoto, listed as major shareholder, has filed trades across 2 companies (mainly through EDINET (Japan FSA)), most often in 株式会社三ッ星 and 株式会社三ツ星. Between 6 July 2022 and 3 April 2023, the trades on record add up to 7 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

On 31 May 2023 came the latest disclosure, a transaction in 株式会社三ッ星. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 58 days. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
