臨時報告書
Major Shareholding Notification Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director. Section 1 explicitly states the reason for filing is a change in a major shareholder ("主要株主に異動がありましたので"), citing Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act. This type of filing in Japan, reporting significant changes in ownership or corporate events outside of routine periodic reports (like 10-K or IR), typically falls under a general regulatory disclosure category. Given the specific nature of reporting a change in major shareholder status, it is a regulatory filing. Since there is no specific code for 'Major Shareholder Change Report' among the provided options, and it is a formal regulatory submission detailing ownership changes, it best fits the general 'Regulatory Filings' category (RNS) or potentially 'Major Shareholding Notification' (MRQ). MRQ is defined as 'Notification of changes in significant share ownership levels (crossing thresholds)'. Since this report details a shareholder dropping below a threshold (from 10.30% to 9.30%), MRQ is the most precise fit among the specialized codes. The document is not an announcement of a report (RPA) but the report itself.

確認書
Report Publication Announcement Classification · 100% confidence The document text contains the header "第３四半期報告書" (Third Quarter Report) and explicitly mentions the period covered: "第76期第３四半期（自2023年10月１日　至2023年12月31日）". It also includes confirmation statements regarding the appropriateness of the contents of this quarterly report, referencing the Financial Instruments and Exchange Act. This structure strongly indicates a comprehensive financial report for an interim period shorter than a year. This aligns perfectly with the definition of an Interim / Quarterly Report (Code: IR). The document length is very short (631 chars), but the content is the report itself (a confirmation/summary page of the quarterly filing), not just an announcement of its publication, making IR more appropriate than RPA or RNS.

四半期報告書－第76期第3四半期(2023/10/01－2023/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Quarterly Report' (第３四半期報告書) for P.S. Mitsubishi Construction Co., Ltd. It contains detailed financial statements, including the balance sheet, income statement, and comprehensive income statement for the third quarter of the fiscal year ending 2024. It is a comprehensive financial report for a period shorter than a full fiscal year, fitting the definition of an Interim/Quarterly Report (IR). 9M 2024

臨時報告書
Major Shareholding Notification Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is submitted to the Kanto Local Finance Bureau Director on December 12, 2023. Section 1 explicitly states the reason for filing: a change in the parent company and major shareholder due to a Tender Offer (公開買付け) conducted by Taisei Corporation. This structure and content—reporting a change in control following a tender offer—is characteristic of a Japanese regulatory filing reporting a significant event, specifically a change in ownership structure. In the provided definitions, this type of mandatory disclosure regarding a change in control or major shareholder status, especially when triggered by a tender offer, aligns best with a general regulatory filing or a specific event report. Since the core event is the change in parent company/major shareholder following a tender offer, and there isn't a specific code for 'Change of Control Report' or 'Tender Offer Report' among the options, the most appropriate classification is the general regulatory filing category, RNS, as it covers mandatory disclosures that don't fit elsewhere, or potentially a filing related to capital/share structure changes (SHA/POS), but the primary purpose here is the disclosure of the change in control itself. Given the context of mandatory disclosure of a change in parent company following a tender offer, RNS (Regulatory Filings) serves as the best fit for this specific Japanese 'Extraordinary Report' detailing the outcome of a takeover bid's settlement.

確認書
Report Publication Announcement Classification · 100% confidence The document text is extremely short (630 characters) and contains a header indicating "第２四半期報告書" (Second Quarter Report) along with a submission date (2023年11月14日) and confirmation by the representative director regarding the appropriateness of the filing based on financial instruments laws. This structure strongly suggests a cover sheet or certification accompanying a formal quarterly report, rather than the comprehensive report itself. Since it confirms the contents of a quarterly report ('四半期報告書') and is very brief, it aligns best with the definition of an Interim/Quarterly Report (IR) or potentially a Regulatory Filing (RNS) if it were just an announcement. However, the content explicitly deals with the 'Second Quarter Report' and its certification, making 'IR' (Interim / Quarterly Report) the most appropriate classification for the underlying document type being certified, even if this specific snippet is just the certification cover. Given the explicit mention of the 'Second Quarter Report' and the confirmation of its contents, the classification should be IR, as this is the core subject matter being addressed, despite the brevity suggesting an RPA/RNS if it were purely an announcement of release. Since the content is the certification *of* the IR, IR is the closest fit among the comprehensive reports.
