Masataka Yamamoto

Masataka Yamamoto is a declared insider at 2 companies; the most frequent names are ゲンダイエージェンシー株式会社 and 山本 正卓. In total, 12 filings cover trades dated from 24 September 2021 to 19 October 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 21 October 2026, reports a transaction in ゲンダイエージェンシー株式会社. The median gap between a trade and its publication by EDINET (Japan FSA) is 4 days. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
