Regulatory Filings Classification · 85% confidence The document is a ‘確認書’ – a confirmation letter by the CEO/COO under Japan’s Financial Instruments and Exchange Act (Art. 24-5) attesting to the appropriateness of the half-year report’s contents. It contains no actual financial statements or substantive financial data. It is therefore an officer certification/attestation rather than the interim report itself and falls under Regulatory Filings (RNS).
