Mansei Corporation: what insiders have been doing
Headquartered in Fukushima-ku, Japan, Mansei Corporation belongs to the Industrials sector and traces its origins to 1947. Filings by its managers are published through EDINET (Japan FSA). The last twelve months, up to 26 October 2026, brought 2 filings signed by 1 insider.
Not one of the filings records a straightforward purchase or sale on the market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
Over the last twelve months, not one insider purchase of Mansei Corporation stock was filed.
With 2 filings in twelve months, the company is quieter than the median of 3 filings across the 3,205 companies we follow on the same exchange. Looking back to 2021, when coverage begins, insiders filed 5 purchases and no sales.
This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
