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 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13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 JMDC Inc. with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains detailed financial statements, management analysis (MDA), and business performance data for the interim period (April 1, 2025, to September 30, 2025). As it is a comprehensive financial report for a period shorter than a full fiscal year containing substantive financial data, it is classified as an Interim/Quarterly Report. H1 2025

訂正臨時報告書
Share Issue/Capital Change Classification · 100% confidence The document is titled "訂正臨時報告書" (Corrected Extraordinary Report) and is filed with the Kanto Local Finance Bureau. Section 1 explicitly states the filing reason is based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act and related regulations, concerning the resolution by the Board of Directors to grant stock acquisition rights (new share warrants) to directors, executive officers, and employees. Section 2 details the specifics of these stock acquisition rights (issuance number, price, exercise conditions, etc.). This content strongly indicates a filing related to capital structure changes or financing activities, specifically the issuance of stock options/warrants. Among the provided codes, 'Capital/Financing Update' (CAP) is the most appropriate fit for a formal filing detailing the terms of a new stock option grant, which is a form of capital management/financing activity disclosure in Japan, often filed as an 'Extraordinary Report' (Rinji Hokokusho). Although it is a formal filing, it is more specific than the general 'RNS' fallback.

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 (定時株主総会) held on June 25, 2025, in accordance with financial regulations. Section 2 details the resolutions, which concern the election of directors. This content—reporting the results of shareholder votes on board appointments following an AGM—directly corresponds to the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to an AGM, the core purpose is reporting the *results* of the vote, not providing the meeting materials (AGM-R) or proxy information (PSI). The document is a formal regulatory filing reporting specific voting outcomes.

確認書
Audit Report / Information Classification · 95% 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 references the Financial Instruments and Exchange Act (金融商品取引法) and confirms the appropriateness of the contents of the Securities Report for the 12th fiscal period (ending March 31, 2025). A Securities Report in the US context is equivalent to a 10-K. Since this is a comprehensive annual filing confirming its contents under financial law, the most appropriate classification is Annual Report (10-K), despite the document appearing to be a certification/confirmation document related to the filing rather than the full report itself. However, given the explicit mention of the 'Securities Report' and the context of annual financial disclosure, 10-K is the closest fit among the provided options for a major annual filing. The document length is very short (586 chars), suggesting it might be a cover or certification page, but the core subject matter points to the annual filing. Revisiting the definitions: 10-K is for the 'Official yearly report covering company activity and full financial performance.' This document is a confirmation *of* that report. If it were just an announcement, RPA or RNS would apply. Since it explicitly deals with the content verification of the annual statutory filing, 10-K remains the strongest thematic match, representing the core annual disclosure requirement. FY 2025

内部統制報告書－第12期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly references the legal basis as "金融商品取引法第24条の４の４第１項" (Financial Instruments and Exchange Act Article 24-4-4, Paragraph 1). This specific report type, detailing the assessment of internal controls over financial reporting, corresponds directly to the requirements for an Annual Report filing in Japan, often filed alongside or as part of the 10-K equivalent structure, but the content itself is the formal Internal Control Report. In the provided classification list, there is no direct code for a standalone 'Internal Control Report' (which is a mandatory component of the annual filing process in Japan, similar to the Sarbanes-Oxley Section 404 report in the US). However, the content is a comprehensive, year-end assessment of internal controls, which is a core component of the full annual disclosure package. Given the options: - 10-K: Official yearly report covering company activity and full financial performance. (This report is a key part of that). - AR: Standalone audit reports, applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports). Since this document is the formal report on internal controls, it is most closely aligned with the comprehensive annual reporting structure. In many contexts, the Sarbanes-Oxley 404 report (Internal Control Report) is considered integral to the 10-K. If the document were just an announcement, RPA would apply, but this is the report itself. Given the comprehensive nature and the reference to the annual financial period ("当連結会計年度の末日である2025年３月31日"), it is best classified as part of the Annual Report structure (10-K), as it is a mandatory, detailed annual disclosure. If a more specific code existed for 'Internal Control Report', that would be chosen. Lacking that, 10-K is the most appropriate category for a comprehensive annual compliance document.
