確認書
Regulatory Filings Classification · 100% 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 regarding 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70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 Tanaka Chemical Corporation in accordance with Article 24-5, Paragraph 1 of the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements (Balance Sheet, Income Statement, Cash Flow Statement) for the interim period ending September 30, 2025. As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2025

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 based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following the resolutions made at the Annual General Meeting (AGM) held on June 27, 2025. Section 2 details the resolutions, specifically the election of four directors, and provides the voting results (votes for, against, abstentions, and passing requirements). This content perfectly matches the definition of reporting the results of a shareholder vote, which corresponds to the Declaration of Voting Results & Voting Rights Announcements (DVA). Although it relates to the AGM, the core content is the voting outcome report, not the AGM presentation materials (AGM-R).

内部統制報告書－第69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 cover page and throughout the text. 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), which mandates the filing of an Internal Control Report in Japan. The content discusses the framework, scope, criteria, procedures, and conclusion regarding the effectiveness of internal controls over financial reporting as of the fiscal year-end (March 31, 2025). This directly corresponds to the definition of an Audit Report / Information (AR), which covers internal or regulatory stress tests and applied accounting principles, although 'AR' is the closest fit among the provided codes for this specific type of regulatory assurance report, which is distinct from a full 10-K or a simple earnings release.

確認書
Audit Report / Information Classification · 95% confidence The document text contains the Japanese phrase "有価証券報告書" (Yūka Shōken Hōkokusho), which translates to 'Securities Report' or 'Annual Securities Report'. It also explicitly mentions the '金融商品取引法' (Financial Instruments and Exchange Act) and confirms the accuracy of the report for the fiscal year ending March 31, 2025. In the context of US/global filings, the comprehensive annual report is typically classified as a 10-K. Although this is a Japanese filing, the content aligns perfectly with the definition of an Annual Report (10-K), which covers full company activity and financial performance for the year. The document itself appears to be a confirmation or cover page related to the filing of the full annual report, but given the explicit reference to the full annual report content and structure, classifying it as the primary annual filing type is appropriate, rather than a mere announcement (RPA/RNS). The length is short, but the content is definitive about the annual filing status. FY 2025

It contains detailed financial statements, business overviews, and management information for the fiscal year ending March 31, 2025. It is the Japanese equivalent of a 10-K. FY 2025
