社外取締役候補者の選任に関するお知らせ
Board/Management Information Classification · 95% confidence The document is a Japanese-language announcement by a company of the Board of Directors’ resolution to nominate and elect a candidate for an outside director, including the candidate’s biography, reasons for selection, and planned appointment date. This clearly fits the definition of a Board/Management Information filing, which covers announcements of changes in the board of directors or senior management.

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 (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第84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 with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. It contains comprehensive financial statements, including the balance sheet, for the interim period (April 1, 2025, to September 30, 2025). It is a formal, substantive financial report for a period shorter than a full fiscal year, fitting the definition of an Interim/Quarterly Report (IR). H1 2025

内部統制報告書－第83期(2024/04/01－2025/03/31)
Governance Information Classification · 100% confidence The document explicitly states in the header section ("【提出書類】") that it is an "内部統制報告書" (Internal Control Report) and cites 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"). The content discusses the framework, scope, criteria, and results of evaluating internal controls over financial reporting ("財務報告に係る内部統制"). This directly corresponds to the definition of an Audit Report / Information (AR), which covers internal or regulatory stress tests and applied accounting principles, although this specific document is an Internal Control Report, which is closely related to the audit function and often filed alongside annual reports or as a standalone compliance document. Given the provided options, 'AR' (Audit Report / Information) is the closest fit for a formal report detailing internal control effectiveness assessment, distinct from the full Annual Report (10-K) or a simple Earnings Release (ER).

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (863 characters) and contains a header structure typical of Japanese regulatory filings, specifically mentioning "【提出書類】確認書" (Filing Document: Confirmation Document) and referencing the Financial Instruments and Exchange Act ("金融商品取引法"). The core content confirms that the Representative Director and President has verified the appropriateness of the contents of the company's Annual Securities Report ("有価証券報告書") for the 83rd fiscal period (April 1, 2024, to March 31, 2025). This document is a formal certification or confirmation related to the accuracy of a primary filing (like a 10-K equivalent in Japan, which is the Yuho or Annual Securities Report). Since it is a confirmation document related to the accuracy of the Annual Securities Report, and not the report itself, it functions as a specific regulatory certification. Given the options, this type of formal confirmation/certification related to statutory filings, which doesn't fit neatly into the main report categories (10-K, IR, ER), is best categorized as a general Regulatory Filing (RNS) or potentially an Audit Report/Information (AR) if it were an auditor's opinion, but here it is management's confirmation. Given the context of confirming the accuracy of the Annual Securities Report, and the lack of a specific code for 'Confirmation of Accuracy of Annual Report', RNS (Regulatory Filings) is the most appropriate fallback for a specific, non-standard regulatory certification document.

有価証券報告書－第83期(2024/04/01－2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of an Annual Report (10-K). The header explicitly identifies it as a 'Securities Report' (有価証券報告書) filed under the Financial Instruments and Exchange Act, covering the fiscal year from April 1, 2024, to March 31, 2025. It contains extensive XBRL tagging and financial data, confirming it is the full annual report rather than an announcement. FY 2025
