確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. It serves as an officer certification confirming the accuracy of a previously filed semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type.

半期報告書－第36期(2025/07/01－2025/12/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains detailed financial statements (balance sheets, income statements, etc.) for the interim period ending December 31, 2025. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 36

Report Publication Announcement Classification · 1% confidence The document is extremely short (588 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' (Director of the Kanto Local Finance Bureau) under the Financial Instruments and Exchange Act. The core content confirms the appropriateness of the '半期報告書' (Half-Year Report) for the period July 1, 2024, to December 31, 2024. Since this document is a confirmation *about* the Half-Year Report, and not the comprehensive report itself, it fits the definition of a general regulatory announcement or confirmation filing that doesn't fit a more specific category like 10-K or ER. Given the options, 'Regulatory Filings' (RNS) is the most appropriate fallback for this type of confirmation document, although 'IR' (Interim/Quarterly Report) is related to the subject matter, this document is a meta-document confirming the IR's accuracy. Following Rule 2 (Menu vs Meal), since this is a short confirmation document rather than the full report, RNS is chosen as the best fit among the provided codes for a miscellaneous regulatory confirmation.
