Okamoto Glass Co., Ltd.: what insiders have been doing
This page follows insider dealings at Okamoto Glass Co., Ltd. as filed with EDINET (Japan FSA), a company from the Technology sector based in Chiba Prefecture, Japan. The group dates from 1947. 2 insiders have disclosed 4 filings since 10 November 2025.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
For context, the typical company on the same exchange (median of 3,419 companies) published 3 filings over the same period, against 4 filings here.
No insider has bought Okamoto Glass Co., Ltd. shares on the open market in the past twelve months. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 8 days. This delay matters because a trade only becomes useful information once it is public.
Other companies in the same sector with recent insider buying flagged by our signals: Core Scientific, Inc./tx and Gitlab Inc. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
