Mitsuru Igarashi

Filings by Mitsuru Igarashi span 2 companies, the busiest being シンプレクス・ホールディングス株式会社 and 五十嵐 充. We count 5 filings; the first trade dates from 22 September 2021 and the latest from 18 November 2025.

The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 26 November 2025, reports a transaction in シンプレクス・ホールディングス株式会社. Typically, a trade is published a median of 5 days after it takes place. 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.
