Major Shareholding Notification Classification · 100% confidence The document is a 'Change Report' (変更報告書) filed under the 'Large Shareholding Report' (大量保有報告書) framework in Japan. It details a change in shareholding percentage by a specific entity (The Japan Steel Works, Ltd.) in another company (Tsukishima Holdings Co., Ltd.). This type of filing is specifically designed to notify the market when a major shareholder's stake crosses certain thresholds or changes significantly. In the provided taxonomy, 'Major Shareholding Notification' (MRQ) is the correct category for such filings.

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report) and explicitly states in Section 1 that it is being submitted because resolutions were passed at the "当社第99回定時株主総会" (Our 99th Annual General Meeting) held on June 23, 2025. Section 2 details the resolutions, which include the approval of the final dividend (剰余金の処分の件) and the election of directors and auditors (取締役選任の件, 監査役選任の件). The core content is the official results of the shareholder votes (賛成, 反対, 棄権) for these agenda items. This directly corresponds to the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA), which covers official results from shareholder votes at any general meeting.

内部統制報告書－第99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 cites the legal basis as "金融商品取引法第24条の４の４第１項" (Financial Instruments and Exchange Act Article 24-4-4 Paragraph 1). This specific filing requirement in Japan mandates the submission of an Internal Control Report, which is a key component of the annual filing process, often accompanying the 10-K equivalent. While the content relates to internal controls, the specific Japanese regulatory document type for this is distinct from the general 'Audit Report' (AR) or 'Annual Report' (10-K). However, among the provided codes, 'AR' (Audit Report / Information) is the closest fit for a formal report detailing internal control assessment, especially since it covers internal/regulatory stress tests and applied accounting principles, which often overlap with internal control reporting scope in a broader sense, or it could be considered a specialized part of the annual reporting cycle. Given the strict definitions, and noting that this is a formal, comprehensive report on internal controls over financial reporting, it aligns best with the scope of 'AR' (Audit Report / Information) compared to other options like ER (Earnings Release) or IR (Interim Report). Since there is no specific code for 'Internal Control Report', and it is a formal report on financial integrity, AR is the most appropriate classification among the choices.
