確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (確認書) filed under 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63期(2025/04/01－2025/09/30)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Nikken Kogaku Co., Ltd. with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. 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 · 1% 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 filed pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were made at the Annual General Meeting (AGM) held on June 26, 2025. Section 2 details the resolutions, including the approval of the dividend distribution (剰余金処分の件) and the election of directors (取締役７名選任の件), along with the voting results. This content—reporting the results of shareholder votes and resolutions passed at a general meeting—perfectly matches the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to the AGM, the primary purpose is reporting the *results* of the votes, not providing the initial AGM materials (AGM-R) or proxy information (PSI). The document length is short (1755 chars), suggesting it is a filing announcing the results rather than the full meeting presentation.

内部統制報告書－第62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 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 (using March 31, 2025, as the base date), and the conclusion that internal controls over financial reporting are effective. This structure and content precisely match the requirements for an Internal Control Report, which is a mandatory filing in Japan, often associated with the annual reporting cycle but distinct from the full 10-K or a general Audit Report. Given the specific Japanese regulatory context and the document's explicit nature, the closest equivalent category that covers internal control reporting, distinct from a general Audit Report (AR) or Annual Report (10-K), is not perfectly mapped in the provided list. However, the content is a formal report on internal controls, which is a key component of annual filings. Since 'AR' is defined as 'Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports)', and this document focuses purely on the internal control assessment framework and results, it fits best under the general 'Audit Report / Information' category (AR) as it relates to the assurance process over financial reporting, or potentially 'Governance Information' (CGR). Given the explicit focus on 'Internal Control Report' (内部統制報告書), which is a formal assurance document, 'AR' is the most appropriate fit among the choices, as it covers reports related to the assurance/audit process, even if it's management's assessment rather than an external auditor's opinion. The document is clearly the report itself, not an announcement of a report, and its length (2431 chars) confirms it is the substantive document.

確認書
Audit Report / Information Classification · 1% confidence The document text contains Japanese regulatory headers such as "【提出書類】 確認書" (Filing Document: Confirmation Document) and references the "金融商品取引法" (Financial Instruments and Exchange Act). It explicitly states that the Representative Director confirmed the appropriateness of the contents of the company's annual securities report ("有価証券報告書") for the fiscal year ending March 31, 2025. This document is a confirmation statement regarding the accuracy of the Annual Securities Report, which is the Japanese equivalent of the US 10-K filing. Since the document is a confirmation/attestation related to the annual filing, and not the full 10-K itself, it most closely aligns with the general regulatory filing category or potentially an Audit Report/Information (AR) if it were an auditor's opinion, but given it's management confirming the filing's accuracy, it fits best under the general regulatory/attestation category. However, the core subject matter is the Annual Report (10-K). In the context of the provided codes, the closest match for a document confirming the accuracy of the annual report, which is a mandatory regulatory filing, is often grouped with the primary report type or a general regulatory filing. Given the options, and recognizing this is a confirmation related to the annual filing, '10-K' is the most relevant category for the underlying subject matter, although 'RNS' (Regulatory Filings) is a possibility if this confirmation itself is considered a separate, minor filing. Since the content is entirely focused on confirming the '有価証券報告書' (Annual Securities Report), classifying it as '10-K' is the most informative choice regarding the document's substance, assuming the system expects the primary report type when confirmation/attestation is present. If this were a US context, this would be an exhibit or part of the 10-K filing process. Given the limited options, 10-K is chosen as the subject matter is the annual report confirmation. FY 2025

有価証券報告書－第62期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the standard annual financial filing required under the Financial Instruments and Exchange Act of Japan. It contains the cover page, fiscal year details (62nd term, 2024-04-01 to 2025-03-31), and XBRL metadata tags typical of a comprehensive annual report. It is equivalent to a 10-K filing in the US market. FY 2025
