Filing Released Lang Actions
確認書
Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, specifically confirming the accuracy of the contents of a Semi-Annual Report (Interim Report). Since it is a regulatory filing confirming the validity of a report rather than the report itself, and it does not fit into specific categories like 10-K or IR, it falls under the general regulatory filing category.

半期報告書-第55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) for the company '株式会社東邦システムサイエンス' (Toho System Science Co., Ltd.) for the period ending September 30, 2025. It contains detailed financial statements, including the balance sheet, income statement, and management analysis, as required by the Financial Instruments and Exchange Act of Japan. This fits the definition of an Interim/Quarterly Report (IR). H1 2026

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 '定時株主総会' (Annual General Meeting) held on June 25, 2025. Section 2 details the resolutions, which include the approval of dividends ('剰余金処分の件') and the election of directors and auditors. This structure—reporting the results of a shareholder meeting—is characteristic of an AGM Result filing. In the provided definitions, 'Declaration of Voting Results & Voting Rights Announcements' (DVA) is the most appropriate fit for reporting the outcome of resolutions passed at a general meeting.

確認書
Audit Report / Information Classification · 95% confidence The document is extremely short (598 characters) and contains a table structure typical of a cover page for a Japanese regulatory filing. Key Japanese terms include '【提出書類】確認書' (Filing Document: Confirmation Document), '【根拠条文】金融商品取引法' (Basis Article: Financial Instruments and Exchange Act), and confirmation by the CEO regarding the appropriateness of the '有価証券報告書' (Annual Securities Report/10-K equivalent) for the fiscal year ending March 31, 2025. This document is not the Annual Report (10-K) itself, but rather a formal confirmation statement required by law accompanying the filing. Since it is a specific regulatory confirmation document that doesn't fit the other specific categories (like DIV, DIRS, ER), and it is a formal filing, it falls best under the general 'Regulatory Filings' (RNS) category, as it is a required regulatory submission accompanying a major report, or potentially an Audit Report/Information (AR) if it were a standalone audit confirmation, but RNS is a safer general regulatory fallback for specific confirmation forms.

内部統制報告書-第54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). It references 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), which mandates the filing of an internal control report by listed companies in Japan. The content discusses the framework, scope, criteria date (March 31, 2025), and the conclusion that internal controls over financial reporting are effective. This directly corresponds to the definition of an Audit Report / Information (AR), which covers internal or regulatory stress tests and applied accounting principles, although in this specific Japanese context, the 'Internal Control Report' is a distinct mandatory filing related to financial reporting integrity, fitting best under the AR category among the provided options, as it is a formal report on internal controls rather than a full annual report (10-K) or a brief announcement.
2025-06-24 Japanese
有価証券報告書-第54期(2024/04/01-2025/03/31)
Annual Report Classification · 100% confidence The document is a Japanese '有価証券報告書' (Yuuka Shouken Houkokusho), which is the standard Japanese equivalent of an Annual Report (10-K). It contains comprehensive financial data, management discussion, and corporate information for the fiscal year ending March 31, 2025. It is not an announcement or a summary, but the full report itself. FY 2025
