確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. It serves as a formal certification by the CEO regarding the accuracy of the Annual Securities Report (Yuuka Shouken Houkokusho). Since it is a regulatory filing required by law to accompany financial reporting but does not constitute the financial report itself, and given the specific nature of the filing, it falls under the general regulatory filing category.

Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). The header explicitly identifies it as '有価証券報告書' (Securities Report) filed under the Financial Instruments and Exchange Act, covering a full fiscal year (2024-10-01 to 2025-09-30).

確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, where the CEO certifies 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, as they do not contain the actual financial statements.
