確認書
Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act of Japan. It confirms the accuracy of the contents of a semi-annual report (Hankihokokusho) for the period ending September 30, 2025. Since this is a regulatory filing required by law to accompany financial reports but does not constitute the financial report itself, and given the specific nature of Japanese regulatory filings that do not fit into other categories, it is classified as a Regulatory Filing (RNS).

AGM Information Classification · 100% confidence The document is titled with headers indicating it is a submission (提出書類: 臨時報告書 - Extraordinary Report) to the Kanto Local Finance Bureau (提出先: 関東財務局長) and is dated June 25, 2025.
