Yamamoto Tsuyoshi

Yamamoto Tsuyoshi, listed as major shareholder, appears in our data through filings on 地盤ネットホールディングス株式会社 shares, published by EDINET (Japan FSA). We count 9 filings; the first trade dates from 16 June 2023 and the latest from 27 February 2026.

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 record was last updated on 6 March 2026 with a transaction in 地盤ネットホールディングス株式会社. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 7 days. This delay matters because a trade only becomes useful information once it is public. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
