確認書
Regulatory Filings Classification · 1% confidence The document is titled '確認書' (Confirmation Letter) and explicitly cites '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 confirming 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80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 Seikagaku Corporation in Japan. It contains comprehensive financial statements (balance sheet, income statement, cash flow analysis) for the interim period from April 1, 2025, to September 30, 2025. It is a formal regulatory filing under the Financial Instruments and Exchange Act, which fits the definition of an Interim/Quarterly Report (IR). H1 80

臨時報告書
AGM Information Classification · 1% confidence The document is titled "臨時報告書" (Extraordinary Report) 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 made at the Annual General Meeting (AGM) held on June 20, 2025. Section 2 details the resolutions, including the approval of the year-end dividend and the election of five directors. The core content is the official reporting of the results of shareholder voting on specific agenda items from a general meeting. This aligns perfectly with 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79期(2024/04/01－2025/03/31)
Governance Information Classification · 1% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the header table. 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 in Japan. The content discusses the framework, scope, criteria, and conclusion regarding the effectiveness of internal controls over financial reporting as of March 31, 2025. This directly corresponds to the requirements for an Audit Report / Information filing, specifically concerning internal controls, which aligns best with the 'AR' (Audit Report / Information) category among the provided options, 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 · 1% confidence The document text contains Japanese characters and includes a table with fields like "【提出書類】" (Filing Document), "【根拠条文】" (Legal Basis), "【提出先】" (Filing Authority), and explicitly mentions "有価証券報告書" (Securities Report) and confirms its appropriateness based on the Financial Instruments and Exchange Act. The confirmation section is signed by the Representative Director and President, confirming the contents of the '第79期（自 2024年4月1日 至 2025年3月31日）の有価証券報告書' (79th period Securities Report for FY ending March 31, 2025). This document is a formal certification or confirmation related to the annual securities report, which is the Japanese equivalent of the US 10-K filing. Since this is a confirmation document related to the full annual report, and not the report itself, it is best classified as a general regulatory filing or potentially related to the Annual Report (10-K). Given the specific nature of confirming the '有価証券報告書' (Securities Report), which is the comprehensive annual filing, the closest equivalent in the provided definitions is '10-K'. However, the document itself is a '確認書' (Confirmation Document) regarding the 10-K. If a specific confirmation code isn't available, and considering the context of comprehensive annual reporting confirmation, 10-K is the most relevant category, although RPA or RNS might also apply if it were just an announcement. Since it contains substantive confirmation details about the annual report's accuracy, I will classify it as 10-K, recognizing it as a document intrinsically linked to the annual filing process.

有価証券報告書－第79期(2024/04/01－2025/03/31)
Annual Report Classification · 1% confidence The document is a Japanese 'Yuuka Shouken Houkokusho' (Securities Report), which is the Japanese equivalent of a 10-K annual report. It contains a cover page with the filing date (2025-06-23), the fiscal year (79th term), and extensive XBRL-like metadata tags indicating comprehensive financial statements and corporate disclosures. It is not an announcement or a summary, but the full annual filing itself. FY 2025
