臨時報告書
Regulatory Filings Classification · 1% confidence The document is a Japanese "臨時報告書" (extraordinary/timely disclosure) filed under Japan’s Financial Instruments and Exchange Act, detailing the change of the company’s statutory auditor. It is not a full annual or interim report, not an earnings release, proxy statement, management change notice (board changes), or any other specific category. It falls under general regulatory announcements of material events (fallback).

確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act. It serves as an officer certification regarding the accuracy of a semi-annual 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 a specific report type.

半期報告書－第95期(2025/04/01－2026/03/31)
Interim / Quarterly Report Classification · 1% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Watanabe Sato Co., Ltd. with the Kanto Local Finance Bureau on November 11, 2025. It covers the interim accounting period from April 1, 2025, to September 30, 2025. It contains detailed financial statements, including the balance sheet and management analysis, which qualifies it as an Interim/Quarterly Report (IR) rather than a mere announcement or certification.

臨時報告書
AGM Information Classification · 1% confidence The document is titled '臨時報告書' (Extraordinary Report) in the header and explicitly states in Section 1 that it is being submitted based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were passed at the Annual General Meeting (定時株主総会) held on June 26, 2025. Section 2 details the resolutions, including dividend approval (剰余金処分の件) and the election of directors and auditors (取締役６名選任の件, 監査役１名選任の件), along with the voting results. This structure—reporting the results of a shareholder meeting—is characteristic of a Declaration of Voting Results & Voting Rights Announcement (DVA). Although it relates to the AGM, the core content is the voting outcome, not the AGM presentation materials (AGM-R).

確認書
Audit Report / Information Classification · 1% confidence The document is extremely short (582 characters) and appears to be a confirmation statement regarding the appropriateness of the contents of a securities report (有価証券報告書 - Yuuka Shouken Houkokusho). The key elements are: '【提出書類】確認書' (Filing Document: Confirmation), reference to the Financial Instruments and Exchange Act (金融商品取引法), and confirmation by the CEO regarding the appropriateness of the '第94期...有価証券報告書' (94th period Securities Report). Since this is a short confirmation document related to the annual filing (which is typically the 10-K equivalent in Japan, but the document itself is not the full report), and it doesn't fit neatly into other specific categories like ER, IR, or AR, it functions as a regulatory confirmation or supplementary filing. Given the options, it is most closely related to the official annual reporting cycle but is not the full Annual Report (10-K). It is a specific regulatory confirmation. Since there is no specific code for a 'Securities Report Confirmation,' and it is a formal regulatory document, the most appropriate fallback is 'Regulatory Filings' (RNS), although it is highly specific to the annual filing process. However, if we strictly interpret the definitions, this document confirms the accuracy of the annual report, which is a mandatory step. Given the context of Japanese filings, this confirmation often accompanies the main filing. Since it is not the full 10-K, and it's not a standard announcement like DIV or DIRS, RNS (Regulatory Filings) is the best fit as a general regulatory document that doesn't match the specific report types.

内部統制報告書－第94期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document header explicitly states the filing type as "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). Section 1 discusses the basic framework for internal controls over financial reporting, and Section 3 concludes that internal controls are effective as of the end of the business year (March 31, 2025). This content directly corresponds to the requirements for an Audit Report / Information filing, specifically concerning internal control assessments, which aligns best with the 'AR' code, as it is a standalone report on internal controls rather than the full annual report (10-K) or a general announcement.
