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, should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第46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 under the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow analysis for the interim period (April 1, 2025, to September 30, 2025). It is a formal regulatory filing containing substantive financial data, which fits the definition of an Interim/Quarterly Report (IR). H1 2026

臨時報告書
Regulatory Filings Classification · 100% confidence The document is explicitly titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the "中国財務局長" (Director of the Kanto Local Finance Bureau). The filing reason states that an event significantly impacting the consolidated financial condition, operating results, and cash flow has occurred, citing Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. The content details a debt waiver (債務免除) received by a subsidiary, resulting in the recognition of a debt waiver gain (債務免除益) in the consolidated financial statements for the first quarter of the fiscal year ending March 2026. This structure—a formal, timely disclosure of a significant, non-periodic financial event—is characteristic of a Japanese Extraordinary Report (or Timely Disclosure). Among the provided codes, 'RNS' (Regulatory Filings) is the most appropriate general category for miscellaneous, non-standardized regulatory disclosures that are not 10-K, IR, or ER, especially when the document is a specific Japanese regulatory filing form (Fifth Series No. 3 Form) detailing a material event. Given the specific nature of the filing (a timely disclosure of a material event under Japanese law), RNS is the best fit as a general regulatory filing category, although it is not one of the highly specific US SEC forms.

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 26, 2025, in accordance with Japanese financial regulations (Financial Instruments and Exchange Act). Section 2 details the resolutions, which include capital reduction, amendment of articles of incorporation, and election of directors. The core content is the official results of the shareholder vote on the resolutions passed at the AGM. This directly corresponds to the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA), which covers official results from shareholder votes at any general meeting.

内部統制報告書－第45期(2024/07/01－2025/03/31)
Governance Information Classification · 100% confidence The document is titled "内部統制報告書" (Internal Control Report) and explicitly states its basis under 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 (基準日: March 31, 2025), and conclusion regarding the effectiveness of internal controls over financial reporting. This structure and content directly correspond to the requirements for an Audit Report or internal control assessment, which aligns best with the 'Audit Report / Information' category (AR), as it is a formal report on internal controls, distinct from a full Annual Report (10-K) or a simple Earnings Release (ER). Although it is a Japanese filing, the content is a formal control assessment.
