Ryuji Arai

Filings by Ryuji Arai span 3 companies, the busiest being 株式会社ビックカメラ, 株式会社シード and 株式会社ヒト・コミュニケーションズ・ホールディングス. Over a trading history stretching from 7 July 2023 to 13 October 2026, the count stands at 6 filings.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

On 20 October 2026 came the latest disclosure, a transaction in 株式会社シード. 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. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
