Kazuo Tsubota

Kazuo Tsubota is a declared insider of 株式会社坪田ラボ (major shareholder), with filings sourced from EDINET (Japan FSA). In total, 6 filings cover trades dated from 24 January 2023 to 28 August 2025.

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.

Most recently, on 2 September 2025, the filings show a transaction in 株式会社坪田ラボ. Filings reach the EDINET (Japan FSA) feed a median of 6 days 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.
