Takafumi Takahashi

Takafumi Takahashi, listed as major shareholder, appears in our data through filings on 株式会社ブレインパッド shares, published by EDINET (Japan FSA). Between 31 January 2023 and 15 December 2025, the trades on record add up to 11 filings.

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 19 December 2025, reports a transaction in 株式会社ブレインパッド. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 7 days. The shorter that gap, the sooner other investors can see what insiders have done. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
