Otsuka Corporation

This profile gathers the share dealings of Otsuka Corporation across 3 companies, led by 日本ナレッジ株式会社, 株式会社AVILEN and 株式会社ライオン事務器. In total, 3 filings cover trades dated from 23 March 2023 to 15 October 2025.

The filings describe grants, exercises and other transfers rather than trades on the open market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

On 17 October 2025 came the latest disclosure, a transaction in 株式会社ライオン事務器. Typically, a trade is published a median of 4 days after it takes place. That lag is the time during which only the insider knows about the trade. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
