訂正有価証券報告書－第114期(2019/04/01－2020/03/31)
Annual Report Classification · 100% confidence The document is titled '訂正有価証券報告書' (Amended Securities Report) and explicitly references '有価証券報告書' (Annual Securities Report) under the Financial Instruments and Exchange Act. In the Japanese regulatory context, the '有価証券報告書' is the equivalent of the US 10-K, serving as the comprehensive annual report. Although this is an amendment, it falls under the 10-K category as it pertains to the annual reporting cycle. FY 2020

Report Publication Announcement Classification · 100% confidence The document is titled "第２四半期報告書" (Second Quarter Report) and contains a confirmation statement regarding the appropriateness of the contents of the half-year report for the period ending September 30, 2024, submitted to the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. This structure, focusing on a comprehensive report for a period shorter than a year (half-year), strongly indicates an Interim/Quarterly Report. The code for this is 'IR'. The document length is very short (561 chars), but it appears to be the certification/cover page *of* the report itself, rather than an announcement *about* the report's publication, as it contains substantive confirmation text regarding the filing's content, not just a link or notice of availability. Therefore, IR is the most appropriate classification.

半期報告書－第119期(2024/04/01－2025/03/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) for RIKEN KEIKI CO., LTD., covering the period from April 1, 2024, to September 30, 2024. It contains detailed financial statements, including the balance sheet, income statement, and comprehensive income statement, as well as management analysis. This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. 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 filed pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were passed at the Annual General Meeting (AGM) held on June 26, 2024. Section 2 details the resolutions, specifically the election of four directors, and provides the voting results (votes for, against, abstentions, and the passing percentage). This content directly corresponds to the official results of a shareholder vote following a general meeting. Therefore, the most appropriate classification is Declaration of Voting Results & Voting Rights Announcements (DVA).

確認書
Audit Report / Information Classification · 98% confidence The document text contains Japanese regulatory headers, specifically mentioning "有価証券報告書" (Securities Report) and referencing the Financial Instruments and Exchange Act ("金融商品取引法"). The content is a confirmation statement ("確認書") signed by the Representative Director, confirming the appropriateness of the contents of the company's 118th period Securities Report (covering April 1, 2023, to March 31, 2024). This confirmation document itself is not the full Annual Report (10-K) or the Interim Report (IR). Since it is a formal regulatory filing related to the annual reporting cycle but is a specific confirmation/attestation document, it falls best under the general 'Regulatory Filings' category (RNS) as a specific confirmation document that doesn't match the definitions for 10-K, AR, or ER. Given the context of confirming the annual report's accuracy, it is a regulatory filing. However, upon reviewing the definitions, the document is a confirmation related to the annual filing cycle. If this were the actual comprehensive annual report, it would be 10-K. Since it is a confirmation document filed with the Kanto Local Finance Bureau, it is a specific regulatory submission. RNS is the best fit as a general regulatory filing that isn't one of the primary reports (10-K, IR) or a specific announcement (DIV, DIRS, etc.). The document length is very short (575 chars), suggesting it is an ancillary filing rather than the main report. FY 2024

内部統制報告書－第118期(2023/04/01－2024/03/31)
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), which mandates the filing of an Internal Control Report in Japan. The content discusses the framework, scope, criteria date (March 31, 2024), and the conclusion regarding the effectiveness of internal controls over financial reporting. This directly corresponds to the requirements for an Audit Report/Information filing, specifically related to internal controls, which aligns best with the 'AR' (Audit Report / Information) category, as it is a formal report on internal controls rather than a general earnings release (ER) or a full annual report (10-K).
