Umebayashi Masanao

Umebayashi Masanao, listed as major shareholder, appears in our data through filings on 株式会社Arent shares, published by EDINET (Japan FSA). We count 5 filings; the first trade dates from 28 March 2023 and the latest from 20 October 2025.

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.

The newest entry dates from 26 December 2025: a transaction, in 株式会社Arent. Typically, a trade is published a median of 21 days after it takes place. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
