Tsukamoto Takuya

All filings by Tsukamoto Takuya on record concern 株式会社GRCS, in the capacity of major shareholder. Between 8 February 2023 and 6 October 2025, the trades on record add up to 4 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

On 26 February 2026 came the latest disclosure, a transaction in 株式会社GRCS. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
