確認書
Regulatory Filings Classification · 100% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '金融商品取引法第24条の５の２第１項' (Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act). It serves as an officer certification regarding the accuracy of a 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26期(2025/08/01－2026/07/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed under the Financial Instruments and Exchange Act of Japan. It contains detailed financial statements, management analysis (MDA), and corporate information for the interim period (August 1, 2025, to January 31, 2026). This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data and analysis for a period shorter than a full fiscal year. H1 2026

確認書
Audit Report / Information Classification · 98% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, Article 24-4-2, Paragraph 1, in Japan. This is a mandatory regulatory filing that accompanies an Annual Securities Report (Yukashoken Hokokusho) to confirm the accuracy of the report's contents. Since it is a specific regulatory filing required by the Japanese Financial Services Agency and does not fit into the other categories like 10-K or IR (which are the reports themselves), it is classified as a Regulatory Filing.

有価証券報告書－第25期(2024/08/01－2025/07/31)
Annual Report Classification · 100% confidence The document is a '有価証券報告書' (Yuuka Shouken Houkokusho), which is the standard Japanese annual securities report required under the Financial Instruments and Exchange Act. It contains comprehensive financial data, business descriptions, and management information for the fiscal year ending July 31, 2025. This corresponds to the 10-K filing category in the provided schema. FY 2025

半期報告書－第25期(2024/08/01－2025/07/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) for the company '株式会社はてな' (Hatena Co., Ltd.) for the period ending January 31, 2025. It contains detailed financial statements, management analysis (MDA), and corporate information as required by the Financial Instruments and Exchange Act of Japan. Since it is a comprehensive interim financial report containing actual financial data and analysis, it is classified as an Interim/Quarterly Report (IR). H1 2025

確認書
Report Publication Announcement Classification · 100% confidence The document text contains a table header indicating it is related to a '第２四半期報告書' (Second Quarter Report) and mentions the fiscal period '第25期中（自 2024年８月１日 至 2025年１月31日）'. It also references the '金融商品取引法' (Financial Instruments and Exchange Act) and confirms the appropriateness of the report's contents. A Second Quarter Report covering a period shorter than a year corresponds to an Interim/Quarterly Report. The code for this is 'IR'. The document length is very short (547 chars), but it appears to be the actual content confirming the filing's accuracy, not just an announcement of publication, making 'IR' more appropriate than 'RPA' or 'RNS'.
