確認書
Regulatory Filings Classification · 75% confidence The document is a Japanese ‘確認書’ (confirmation letter) submitted under the Financial Instruments and Exchange Act (Article 24-4-2-1) to the Kanto Finance Bureau, confirming the accuracy of the company’s annual securities report. It is not the annual report itself (10-K), nor is it an earnings release, dividend notice, or other specific category. It is a regulatory compliance filing that does not fit any of the specialized categories, so it falls under the general Regulatory Filings (RNS) category.

Regulatory Filings Classification · 95% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act.

半期報告書－第15期(2025/01/01－2025/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed by 株式会社Welby (Welby Inc.) with the Kanto Local Finance Bureau. It contains detailed financial statements, management analysis (MDA), and corporate information for the interim period (January 1, 2025, to June 30, 2025).

内部統制報告書－第14期(2024/01/01－2024/12/31)
Governance Information Classification · 100% confidence The document contains Japanese text with clear regulatory headers and content structure typical of an internal control report. Key phrases include: "【提出書類】 内部統制報告書" (Filing Document: Internal Control Report), "【根拠条文】 金融商品取引法第24条の４の４第１項" (Basis Article: Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act), and sections discussing the framework, scope, and results of the internal control assessment ("財務報告に係る内部統制の基本的枠組みに関する事項", "評価結果に関する事項"). This directly corresponds to the requirements for an Audit Report / Information filing, specifically focusing on internal controls as mandated by Japanese financial regulations. Given the specific focus on internal control assessment results, the most appropriate code is AR (Audit Report / Information), as it covers internal or regulatory stress tests/reports that are not the full Annual Report (10-K).
