新中期経営計画の策定に関するお知らせ
Investor Presentation Classification · 85% confidence The document is a corporate notice dated June 1, 2026 announcing the formulation of a new medium-term management plan (“中期経営計画2030”) and immediately attaches the full slide-style plan materials. It includes a structured table of contents, “社長メッセージ,” retrospective performance review, and detailed forward-looking strategy, financial targets, capital allocation, and shareholder return policy. The length (>20,000 characters) confirms it is not merely an announcement of a report (RPA) but the report itself. Its format—with slide numbers, charts, and narrative—matches an investor presentation rather than an annual or quarterly statutory report. Therefore, it should be classified as an Investor Presentation (IP).

定款一部変更に関するお知らせ
Proxy Solicitation & Information Statement Classification · 90% confidence The document is a pre-AGM notice announcing a shareholder meeting agenda item (partial amendment of the Articles of Incorporation) and providing details for the upcoming ordinary general meeting. This fits the definition of Proxy Solicitation & Information Statement (materials sent to shareholders to provide information and request votes).

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, Article 24-5-2, Paragraph 1. It serves as an officer certification confirming the accuracy of the contents of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report type (in this case, a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第45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 management analysis for the interim period (April 1, 2025, to September 30, 2025). It is a formal regulatory filing containing substantive financial data, which aligns with the definition of an Interim/Quarterly Report (IR). H1 2026

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 is submitted to the Kanto Local Finance Bureau. Section 1 explicitly states the reason for filing is that resolutions were passed at the company's Annual General Meeting (定時株主総会) held on June 26, 2025, pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. Section 2 details the resolutions, which include the approval of the surplus appropriation (dividend) and the election of eight directors. The content is a formal report on the results of a shareholder meeting, specifically detailing the voting outcomes for the resolutions. This aligns perfectly with the definition of reporting the results of shareholder votes, which corresponds to the Declaration of Voting Results & Voting Rights Announcements (DVA). Although it relates to the AGM, the core content is the voting result declaration, not the AGM presentation materials (AGM-R).

内部統制報告書－第44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" (Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act). It details the scope, criteria (based on the Financial Accounting Standards Board's framework), and the conclusion that internal controls over financial reporting are effective as of the fiscal year-end (March 31, 2025). This structure and content precisely match the requirements for an Internal Control Report, which is a mandatory disclosure in Japan, often filed alongside the Annual Securities Report (10-K equivalent). Given the specific nature of reporting on internal controls over financial reporting, the most appropriate classification among the provided options is 'Audit Report / Information' (AR), as it deals with the assurance and structure of financial reporting integrity, although it is distinct from a standard external audit opinion. However, since the provided definitions do not have a specific code for the Japanese 'Internal Control Report' (which is often filed as part of the annual filing but is a distinct document), I must choose the closest fit. 'AR' covers 'applied accounting principles, and results of internal or regulatory stress tests (excluding full Annual Reports)'. An internal control report is a key component related to the integrity of financial reporting, making AR the best fit among the choices, as it is not a 10-K, ER, or IR.
