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 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, as they do not contain the actual financial statements.

半期報告書－第96期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Nippon Kodoshi Corporation in accordance with the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow statement for the interim period ending September 30, 2025. As it is a formal, substantive financial report for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the Annual General Meeting (AGM) held on June 19, 2025, in accordance with financial regulations. Section 2 details the resolutions, including the approval of the final dividend (剰余金処分) and the election of directors and an auditor. This structure—reporting the results of a shareholder meeting (AGM) concerning dividends and board elections—is characteristic of a filing announcing voting outcomes. The closest specific category is 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it is a regulatory filing, DVA is more specific than the general 'RNS' fallback.

内部統制報告書－第95期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the header and within the table structure. It references the legal basis as Article 24-4-4, Paragraph 1 of 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 framework, scope, criteria (as of March 31, 2025), and the conclusion that internal controls over financial reporting are effective. This content aligns perfectly with the requirements for an internal control report, which is often filed alongside the Annual Report (10-K) but is a distinct regulatory document in Japan, often classified under Audit/Regulatory reporting. Given the specific nature of reporting on internal controls over financial reporting, the closest fit among the provided codes is 'AR' (Audit Report / Information), as it deals with the assurance and structure surrounding financial reporting integrity, distinct from the full 10-K or a simple earnings release.

確認書
Audit Report / Information Classification · 95% confidence The document text contains Japanese characters and includes the header "有価証券報告書（通常方式）" which translates to 'Securities Report (Normal Method)'. It explicitly mentions the '金融商品取引法' (Financial Instruments and Exchange Act) and confirms the appropriateness of the contents of the Securities Report for the fiscal year ending March 31, 2025, signed by the Representative Director and President. In the context of Japanese regulatory filings, a comprehensive annual report filed under the Financial Instruments and Exchange Act is equivalent to a US 10-K. Since this document is the confirmation/attestation regarding the accuracy of the full annual report, it is intrinsically linked to the Annual Report (10-K). However, given the provided definitions, the most fitting category for a comprehensive annual financial disclosure document is '10-K'. The document is short (577 chars) and appears to be an attestation page or cover sheet *for* the full report, but the core subject matter is the annual financial disclosure itself, which aligns best with the 10-K definition ('Official yearly report covering company activity and full financial performance'). If a specific Japanese equivalent code existed, it would be used, but 10-K is the closest functional match for a full annual filing confirmation. FY 2025

有価証券報告書－第95期(2024/04/01－2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese '有価証券報告書' (Yuuka Shouken Houkokusho), which is the standard Japanese equivalent of an Annual Report (10-K). It contains detailed financial statements, business indicators, and management information for the fiscal year ending March 31, 2025. The document structure, including the cover page and the 'Part 1: Corporate Information' section, confirms it is the full annual filing, not an announcement or summary. FY 2025
