確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act of Japan. It serves as an officer certification regarding the accuracy of the contents of a semi-annual report. Per the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report (in this case, a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself, as they do not contain the actual financial statements.

有価証券届出書（参照方式）
Share Issue/Capital Change Classification · 100% confidence The document is a '有価証券届出書' (Securities Registration Statement) filed with the Kanto Local Finance Bureau by NHK Spring Co., Ltd. It details a third-party allotment of shares related to a Board Benefit Trust (BBT-RS) compensation plan. This type of filing is a formal regulatory document required for the issuance of new securities or the disposal of treasury shares, which falls under the category of share issuance and capital changes.

自己株券買付状況報告書（法２４条の６第１項に基づくもの）
Transaction in Own Shares Classification · 100% confidence The document title is "自己株券買付状況報告書（法24条の６第１項に基づくもの）" which translates to "Report on the Status of Treasury Stock Acquisition (Based on Article 24-6, Paragraph 1 of the Financial Instruments and Exchange Act)". This document details the company's treasury stock acquisition activities over a specific reporting period (June 1, 2025, to June 30, 2025), including the total number of shares acquired and the total value, referencing the Financial Instruments and Exchange Act. This specific reporting requirement for share repurchases aligns directly with the definition of a filing related to the company buying back or selling its own shares. Therefore, the appropriate classification is Transaction in Own Shares (POS).

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 submitted pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, following the resolutions passed at the 105th Annual General Meeting (AGM) held on June 25, 2025. Section 2 details the resolutions, including dividend approval, director elections, and shareholder proposals, along with the voting results (Yes/No/Abstain counts). This structure—a formal report detailing the outcomes of a shareholder meeting—is characteristic of a filing reporting AGM results. While it relates to the AGM, the core content is the official declaration of voting outcomes, which aligns best with the 'Declaration of Voting Results & Voting Rights Announcements' (DVA). It is not the AGM presentation (AGM-R) nor the proxy materials (PSI), but the post-meeting official result filing.

内部統制報告書－第105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). It details the scope, criteria (using the standards set by the Financial Accounting Standards Board), and the conclusion that internal controls over financial reporting are effective as of the fiscal year-end (March 31, 2025). This structure and content definitively identify it as a report concerning internal controls over financial reporting, which aligns with the definition of an Audit Report / Information (AR), especially since it is a standalone report on internal control assessment rather than the full Annual Report (10-K). Given the specific nature of the content, AR is the most appropriate classification among the provided options, as it covers internal/regulatory stress tests or specific audit-related reports.
