Minoru Matsushima

Filings by Minoru Matsushima span 2 companies, the busiest being 日本エコシステム株式会社 and 松島 穣. The record holds 9 filings, for trades running from 8 October 2021 to 15 August 2025.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

The record was last updated on 1 September 2025 with a transaction in 日本エコシステム株式会社. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 19 days. The shorter that gap, the sooner other investors can see what insiders have done. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
