確認書
Regulatory Filings Classification · 1% confidence The document is titled '確認書' (Confirmation Letter) and explicitly references '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 confirming 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 (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第77期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Daiho Corporation in Japan. It contains detailed financial statements, management analysis, and audit information for the interim period ending September 30, 2025. According to the filing definitions, a comprehensive financial report for a period shorter than a full fiscal year (such as a half-year report) containing actual financial statements is classified as an Interim / Quarterly Report (IR).

臨時報告書
AGM Information Classification · 1% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director on July 1, 2025. Section 1 explicitly states the reason for filing: '2025年６月27日開催の当社第76回定時株主総会において決議事項が決議されましたので...' (Because resolutions were made at the 76th Annual General Meeting held on June 27, 2025...). Section 2 details the resolutions, which include the approval of the final dividend (Item 1), amendment of the articles of incorporation (Item 2), and the election of 13 directors and 3 auditors (Items 3, 4, and 5). The content is a formal report detailing the results of shareholder votes on agenda items from the Annual General Meeting (AGM). This perfectly matches the definition of reporting voting results from a general meeting. Therefore, the appropriate code is DVA (Declaration of Voting Results & Voting Rights Announcements).

確認書
Audit Report / Information Classification · 1% confidence The document text contains Japanese characters and includes the title "有価証券報告書（通常方式）" which translates to "Securities Report (Regular Format)". It also references the "金融商品取引法" (Financial Instruments and Exchange Act) and lists the filing date ("提出日") and company information. A Securities Report in the context of major regulatory filings, especially when comprehensive, strongly corresponds to the US SEC's 10-K filing, which is the official yearly report covering company activity and full financial performance. Although the Japanese term is broader, in the context of the provided definitions, the comprehensive annual report aligns best with the '10-K' category, as it is not merely an announcement (RPA) but the core document itself, despite being a Japanese filing. The document length is short (709 chars), but the content is the certification/cover page of the full report, not just an announcement of its availability. Given the explicit mention of the annual reporting period (implied by the fiscal year ending March 31, 2025, for the 76th period), 10-K is the most appropriate classification for a full annual statutory report.

内部統制報告書－第76期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly states its basis in the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項). It details the scope, criteria, and procedures for evaluating internal controls over financial reporting as of the fiscal year-end (March 31, 2025). This structure and content definitively identify it as a formal internal control report, which aligns with the comprehensive reporting required in annual filings, but is specifically mandated under Japanese regulations for internal control assessment. Given the options, this document is a specific type of regulatory report focusing on internal controls, which is often filed alongside the annual report (10-K equivalent) or as a standalone compliance document. Since there is no specific code for a Japanese 'Internal Control Report' (which is often part of the 10-K equivalent filing in the US context), we must look at the closest fit. It is not an Audit Report (AR), nor is it a general Earnings Release (ER) or Interim Report (IR). It is a comprehensive report detailing internal control effectiveness. In the context of the provided definitions, the closest category for a comprehensive, formal, regulatory report detailing internal processes and effectiveness, distinct from a simple audit opinion or earnings summary, is often grouped with formal annual reporting structures. However, since the document is a standalone report on internal controls, and not the full annual report (10-K), and it is not a general audit report (AR), it is best classified as a specific regulatory filing that doesn't fit the other categories. Given the strict definitions, and recognizing this is a formal, comprehensive report, if it were a US filing, it would be part of the 10-K. Since it is a specific compliance document, and not an announcement of a report (RPA), the most appropriate general category for a formal, non-earnings/non-audit report is often 'Regulatory Filings' (RNS) if a more specific code is unavailable, or potentially 'Audit Report / Information' (AR) if the scope is interpreted broadly to include control assurance. However, '内部統制報告書' is a distinct requirement. Given the options, and recognizing this is a formal, comprehensive report required by law, it is a specific type of regulatory filing. Since 'AR' is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests', and this is an internal control report, it fits the 'internal' aspect better than other options. However, 'RNS' is the fallback for miscellaneous regulatory filings. Given the document's nature as a formal, required compliance document that is not a standard earnings release or general audit opinion, 'RNS' (Regulatory Filings) is the safest fallback, although 'AR' is plausible if internal control reports are grouped with assurance reports. I will lean towards 'AR' as internal control reports are closely related to assurance/audit functions, even if not strictly an external audit opinion.

有価証券報告書－第76期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuuka Shouken Houkokusho' (Annual Securities Report), which is the Japanese equivalent of a 10-K. It explicitly states '有価証券報告書' (Annual Securities Report) in the header, cites the Financial Instruments and Exchange Act Article 24, Paragraph 1, and covers a full fiscal year (第76期, 2024-04-01 to 2025-03-31). It contains extensive XBRL tagging and financial data, confirming it is the full annual report rather than an announcement. FY 2025
