Mitsuo Kobayashi

All filings by Mitsuo Kobayashi on record concern 理研ビタミン株式会社, in the capacity of major shareholder. We count 3 filings; the first trade dates from 3 July 2023 and the latest from 4 August 2026.

Not one of the filings records a straightforward purchase or sale on the market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

On 7 August 2026 came the latest disclosure, a transaction in 理研ビタミン株式会社. Filings reach the EDINET (Japan FSA) feed a median of 3 days after the trade. That lag is the time during which only the insider knows about the trade. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
