Filing Released Lang Actions
訂正発行登録書
Capital/Financing Update Classification · 98% confidence The document is titled "訂正発行登録書" (Correction Registration Statement) and is submitted to the "関東財務局長" (Kanto Local Finance Bureau Director). It explicitly mentions the type of security as "社債" (Corporate Bonds) and details the original filing date, effective date, and validity period of the registration. The key indicator is the document type itself, which relates to the registration of securities issuance (Capital/Financing Update). Since this is a formal registration document concerning the issuance of bonds (a financing activity), the most appropriate category is Capital/Financing Update (CAP). It is not a general earnings release (ER), an annual report (10-K), or a simple announcement of a report (RPA), but the core financing document itself, albeit a correction to the registration.

臨時報告書
AGM Information Classification · 100% confidence The document explicitly states in the header section that the filing type is "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the "関東財務局長" (Kanto Local Finance Bureau Director). The body of the text details the results of the "第165回定時株主総会" (165th Annual General Meeting) held on June 24, 2025, including resolutions passed regarding dividend distribution (剰余金の処分) and the election of directors and auditors. This content—reporting the results of a shareholder meeting—perfectly matches the definition of an AGM-R (AGM Information/Results). Although it reports on the AGM, the specific Japanese filing type (臨時報告書) often corresponds to filings reporting meeting outcomes, which aligns best with AGM-R among the provided codes, rather than just a general regulatory filing (RNS) or a proxy statement (PSI) which precedes the meeting.

内部統制報告書－第165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) based on the Financial Instruments and Exchange Act ("金融商品取引法第24条の４の４第１項"). Section 1 discusses the framework for internal controls over financial reporting, Section 2 details the scope, criteria date (March 31, 2025), and procedures for the evaluation, and Section 3 concludes that the internal controls are effective. This content directly corresponds to the requirements for an Audit Report / Information filing, specifically concerning internal controls, which aligns best with the definition for 'Audit Report / Information' (AR), as it is a formal report on internal control effectiveness, distinct from a full Annual Report (10-K) or a simple Earnings Release (ER).

確認書
Audit Report / Information Classification · 98% confidence The document is titled '確認書' (Confirmation Document) and explicitly references the '金融商品取引法' (Financial Instruments and Exchange Act) and the submission to the '関東財務局長' (Kanto Local Finance Bureau Director). It contains a confirmation statement by the Representative Director and President regarding the appropriateness of the contents of the company's '有価証券報告書' (Securities Report) for the fiscal year ended March 31, 2025. In the US context, this strongly resembles a CEO/CFO certification often accompanying a 10-K filing, but the document itself is the certification/confirmation, not the full annual report (10-K) or a general audit report (AR). Given the options, this document is a specific regulatory confirmation related to the annual filing process. Since it is a confirmation related to the annual filing (Securities Report), and not the full report itself, it doesn't fit 10-K or AR perfectly. However, in the context of Japanese filings, this confirmation is a mandatory component of the annual disclosure package. Since there is no specific code for a 'Securities Report Certification', and it is a formal regulatory document, it is best classified as a general Regulatory Filing (RNS) or potentially related to Governance (CGR) or Audit (AR). Given the direct link to the annual 'Securities Report' (which is the Japanese equivalent of a 10-K), and the nature of the confirmation, it is a highly specific regulatory document. Since the document is short and is a confirmation *about* the annual report, and not the report itself, RNS is the most appropriate fallback for a specific regulatory confirmation that isn't a standard report type. However, if we interpret 'AR' (Audit Report / Information) broadly to include mandatory certifications related to the annual financial statements, it could fit. Given the explicit reference to the '有価証券報告書' (Securities Report), and the lack of a specific certification code, RNS is the safest general regulatory classification, although it is highly related to the annual filing cycle.

有価証券報告書－第165期(2024/04/01－2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuuka Shouken Houkokusho' (Annual Securities Report), which is the Japanese equivalent of a 10-K. The header explicitly identifies it as '有価証券報告書' (Annual Securities Report) filed under the Financial Instruments and Exchange Act, covering the fiscal year from April 1, 2024, to March 31, 2025. It contains comprehensive financial data and corporate information, fitting the definition of an Annual Report. FY 2025

自己株券買付状況報告書（法２４条の６第１項に基づくもの）
Transaction in Own Shares Classification · 100% confidence The document header explicitly states the filing type as "自己株券買付状況報告書" (Report on the Status of Treasury Stock Acquisition). The content details the acquisition of treasury stock (自己株式) during a specific reporting period (May 1 to May 31, 2025), including the number of shares acquired daily and the cumulative total. This directly corresponds to the definition of a report detailing the company buying back or selling its own shares. In the provided classification list, this aligns perfectly with 'Transaction in Own Shares' (Code: POS). The document is a detailed report, not an announcement of a report, so RPA/RNS is not appropriate.
