確認書
Regulatory Filings Classification · 72% confidence The document is a Japanese “確認書” (Confirmation Letter) filed under the Financial Instruments and Exchange Law to the Kanto Finance Bureau, whereby the CEO confirms the accuracy of the “有価証券報告書” (annual securities report) for the fiscal year. It is not the actual annual report (10-K equivalent) but a required regulatory certification letter. It does not fit any specific categories like Audit Report or Management Disclosure, so it falls into the general Regulatory Filings category.

確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, specifically related to the accuracy of the Second Quarter Report (Interim Report). While it references the interim report, the document itself is a formal regulatory filing confirming the validity of the financial statements for the period ending June 30, 2025. Since it is a specific regulatory requirement for filing financial reports in Japan and does not fit into the other categories like 'IR' (which would be the report itself) or 'RPA' (which is an announcement), it is best classified as a Regulatory Filing.
