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 of Japan. It serves as an officer certification confirming the accuracy of a previously filed semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report type, should be classified as Regulatory Filings (RNS).

半期報告書
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed by MediciNova, Inc. with the Kanto Local Finance Bureau in Japan. It contains detailed financial data, including balance sheets, income statements, and cash flow statements for the interim period ending June 30, 2025. As it is a comprehensive financial report for a period shorter than a full fiscal year containing substantive financial data, it is classified as an Interim/Quarterly Report. H1 2025

臨時報告書
Declaration of Voting Results & Voting Rights Announcements Classification · 99% confidence The document is titled '臨時報告書' (Extraordinary Report) and is submitted to the Kanto Local Finance Bureau Director on June 25, 2025. Section 1, '提出理由' (Reason for Submission), explicitly states that the report is being filed based on Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were passed at the company's Annual General Meeting (AGM) held on June 17, 2025. Section 2 details the resolutions passed, including the election of a director and the approval of the independent registered accounting firm, along with the voting results (votes for, against, abstentions). This content perfectly matches the description of reporting the results of a shareholder vote following a general meeting. The most specific code for reporting official results from shareholder votes at any general meeting is DVA (Declaration of Voting Results & Voting Rights Announcements). Although it relates to an AGM, the core content is the voting outcome declaration, not the AGM presentation materials (AGM-R) or the proxy solicitation materials (PSI).

内部統制報告書
Audit Report / Information Classification · 100% confidence The document contains a 'Report of Independent Registered Public Accounting Firm' which explicitly states an 'Opinion on Internal Control over Financial Reporting' as of December 31, 2024, based on COSO criteria. It also includes a section titled '内部統制報告書' (Internal Control Report) detailing the basis for evaluation, scope, and the conclusion that internal controls over financial reporting were effective as of the year-end date. This structure—an auditor's opinion on internal controls combined with the management's internal control report—is characteristic of the documentation required for the annual filing concerning internal controls, which often accompanies the 10-K or is filed separately as an Audit Report/Information, especially when it focuses specifically on the audit of internal controls rather than the full financial statements themselves. Since the primary focus here is the formal opinion and report on the effectiveness of internal controls over financial reporting, the most fitting category is 'Audit Report / Information' (AR), as it is a standalone audit report focusing on controls, distinct from the comprehensive 10-K or a simple Earnings Release (ER). The presence of the auditor's report and the explicit reference to internal control testing strongly supports AR. FY 2024

確認書
Audit Report / Information Classification · 95% confidence The document is titled "確認書" (Confirmation Document) and explicitly references Article 24-4-2, Paragraph 1 of the Financial Instruments and Exchange Act (金融商品取引法第24条の４の２第１項). This specific article relates to the certification of the appropriateness of the contents of the Annual Securities Report (有価証券報告書) by the CEO and CFO. The text confirms the appropriateness of the company's '2024年度...有価証券報告書' (Annual Securities Report for the fiscal year 2024). In the US context, the equivalent comprehensive annual report is the 10-K. Since this document is the formal certification accompanying or related to the Annual Securities Report, and given the definitions provided, it is most closely associated with the Annual Report filing (10-K), as it directly attests to the accuracy of that report. It is not the report itself, but a mandatory certification document related to it. However, among the provided codes, 10-K is the most relevant category for annual financial reporting certification. Given the short length and the nature of the document (a certification/confirmation), it could potentially be classified as RNS if it were a general regulatory filing, but its specific content points directly to the annual filing process. I will classify it as 10-K as it pertains directly to the Annual Report's integrity. FY 2024

有価証券報告書
Annual Report Classification · 100% confidence The document contains a full audit report from an independent registered public accounting firm (BDO USA, P.C.) followed by a comprehensive Japanese '有価証券報告書' (Securities Report). This report includes detailed financial statements, management's discussion and analysis, corporate governance information, and business risk disclosures for the fiscal year ending December 31, 2024. As it is a comprehensive annual financial filing containing audited financial statements, it is classified as a 10-K (Annual Report). FY 2024
