訂正有価証券報告書－第96期(2022/04/01－2023/03/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yukashoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). The header explicitly identifies it as a 'Securities Report' (有価証券報告書) filed under the Financial Instruments and Exchange Act, covering the fiscal year from April 1, 2022, to March 31, 2023. It contains extensive XBRL tagging and financial data, confirming it is the full annual report rather than an announcement or summary. FY 2023

確認書
Report Publication Announcement Classification · 100% confidence The document is extremely short (595 characters) and contains a header section typical of Japanese regulatory filings, specifically mentioning a '確認書' (Confirmation Document) submitted to the '関東財務局長' (Kanto Local Finance Bureau Director) based on Article 24-4-8, Paragraph 1 of the Financial Instruments and Exchange Act. The main body confirms the appropriateness of the '四半期報告書' (Quarterly Report) for the third quarter (ending December 31, 2023). Since this document is a confirmation *about* a quarterly report, and not the comprehensive quarterly report itself, it fits best under the category for general regulatory announcements or filings that confirm compliance related to periodic reports. Given the options, 'Regulatory Filings' (RNS) is the most appropriate fallback for this specific compliance confirmation document, as it is not the full Interim Report (IR) or an Earnings Release (ER). However, since it explicitly deals with the content of a Quarterly Report, and is a formal confirmation document, it is a specific type of regulatory filing. Given the definitions, RNS is the best fit for a miscellaneous regulatory confirmation.

Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, specifically confirming the accuracy of the contents of a Quarterly Report (四半期報告書) for the second quarter of the 97th fiscal period. Since this is a regulatory filing confirming the validity of a report rather than the report itself, and it does not fit into the specific categories for financial statements or earnings releases, it falls under the general regulatory filing category.
