The reasons the company gives

The company's own explanation, not something inferred from the numbers.

For 朱殷卿 (Shu Inkyō), the amount paid for outsourced consulting services to 株式会社コアバリューマネジメント, where he serves as representative director, exceeded 2% of that company's sales in each of fiscal years 2023 through 2025. However, the company explained that the transactions ended on 31 March 2026 and that no payments have been made since then, so there is no special relationship that could give rise to a conflict of interest with general shareholders. For 三村孝仁 (Mimura Takahito) and 小野純司 (Ono Junji), the company corrected and changed the matters concerning independence in relation to their former employers and other concurrent positions, as well as their transaction history.
