確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a report (in this case, a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

Audit Report / Information Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, Article 24-4-2, Paragraph 1. This is a standard regulatory filing in Japan that accompanies an Annual Securities Report (Yukashoken Hokokusho) to confirm the accuracy of the report's contents. Since it is a specific regulatory filing required by law that does not fit into the primary financial report categories (like 10-K or IR) and is not merely an announcement of a report, it falls under the Regulatory Filings category.
