確認書
Regulatory Filings Classification · 100% 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, even if they reference a report (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.

半期報告書－第96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) filed under the Financial Instruments and Exchange Act of Japan. It contains comprehensive financial statements, including the balance sheet, income statement, and cash flow statement for the interim period (April 1, 2025, to September 30, 2025). As it is a formal, comprehensive financial report for a period shorter than a full fiscal year, it falls under the 'Interim / Quarterly Report' category. H1 2026

臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being filed pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following the resolutions passed at the Annual General Meeting (AGM) held on June 27, 2025. Section 2 details the resolutions, which include the approval of dividends (剰余金の処分), the election of directors (取締役選任), and the election of auditors (監査役選任). These are classic outcomes reported immediately after an AGM. Since the document reports the *results* of the shareholder vote, it aligns perfectly with the definition of Declaration of Voting Results & Voting Rights Announcements (DVA). Although it relates to the AGM, DVA is more specific for reporting the voting outcomes than AGM-R (which is for presentations/materials). The document length is relatively short (2561 chars) and serves as a formal regulatory disclosure of voting results.

内部統制報告書－第95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 references the legal basis as "金融商品取引法第24条の４の４第１項" (Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act). This structure and content are characteristic of a formal report assessing internal controls over financial reporting, which is typically filed annually in Japan, similar in function to a Sarbanes-Oxley 404 report in the US context. Although the Japanese filing is not explicitly named '10-K', its function as a comprehensive annual assessment of internal controls aligns most closely with the purpose of an Annual Report (10-K) or a specific Audit/Control Report. Given the specific focus on internal control assessment ('内部統制報告書'), the most appropriate classification among the provided options is 'Audit Report / Information' (AR), as it deals with the results of internal/regulatory assessments of financial reporting integrity, distinct from the full annual financial statements (10-K) or a simple earnings release (ER). The document is a complete report, not an announcement of a report (ruling 2 does not apply).

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act. It serves as an officer's certification regarding the accuracy of the company's Annual Securities Report (有価証券報告書). According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report, should be classified as Regulatory Filings (RNS) rather than the report itself.

有価証券報告書－第95期(2024/04/01－2025/03/31)
Annual Report Classification · 100% 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 formal cover page identifying the company (Nippon Seisen Co., Ltd.), the fiscal period (95th term, ending March 31, 2025), and the regulatory filing basis (Financial Instruments and Exchange Act). The document includes extensive XBRL-like metadata tags typical of official annual filings submitted to the Kanto Local Finance Bureau. FY 2025
