訂正発行登録書
Capital/Financing Update Classification · 1% confidence The document is titled “訂正発行登録書” filed with the Kanto Finance Bureau – a correction to the prior issuance registration statement for corporate bonds (社債). It details amendments to the registration of debt securities (bond issuance), including registration numbers, effective dates, and updated financial indicators. This is clearly an update on the company’s financing activity (bond issuance), thus fitting the “Capital/Financing Update” category. It is not a share issue (SHA) nor a repurchase (POS), nor merely a publication announcement (RPA). Hence it should be classified as CAP.

確認書
Regulatory Filings Classification · 1% 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 regarding the accuracy of a previously filed report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference other report types.

It contains detailed financial statements, management analysis (MDA), and segment information for the interim period (April 1, 2025, to September 30, 2025). Although it is a correction, it functions as an Interim/Quarterly Report (IR) as it provides the full financial data and analysis for the period.

Audit Report / Information Classification · 1% confidence The document is a standalone Internal Control Report (“内部統制報告書”) filed under the Financial Instruments and Exchange Act (FIEA) Article 24-4-4, detailing the company’s internal control framework, evaluation of controls over financial reporting, identified deficiencies, and remediation measures. It is not a full Annual Report (10-K), not an earnings release or management commentary, but rather a specific internal control/audit‐related report. This aligns with the definition of Audit Report / Information (Code: AR). FY 2025
