内部統制報告書－第56期(2022/10/01－2023/09/30)
Governance Information Classification · 100% confidence The document is explicitly titled "内部統制報告書" (Internal Control Report) in the cover section and throughout the text. It references the legal basis as Article 24-4-4, Paragraph 1 of the Financial Instruments and Exchange Act (金融商品取引法第24条の４の４第１項), which mandates the filing of an Internal Control Report. The content details the framework, scope, criteria (based on the Financial Accounting Standards Board's criteria), and the conclusion that internal controls over financial reporting are effective as of the fiscal year-end (September 30, 2023). This directly corresponds to the definition of an Audit Report / Information (AR), which covers internal or regulatory stress tests and applied accounting principles, although this specific document focuses on internal controls over financial reporting, which is a core component often filed alongside or as part of the annual audit process, but distinct from the full 10-K. Given the specific focus on the 'Internal Control Report' (内部統制報告書), the closest fit among the provided codes is 'AR' (Audit Report / Information), as it deals with the assessment of internal controls and accounting principles, which is a key part of the audit function, distinct from a full annual report (10-K) or an earnings release (ER).

有価証券報告書－第56期(2022/10/01－2023/09/30)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of a 10-K annual report. It contains the official filing header, the fiscal year period (2022-10-01 to 2023-09-30), and extensive XBRL-like metadata tags indicating it is a comprehensive annual financial disclosure rather than a mere announcement or summary.

Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-4-8 of the Financial Instruments and Exchange Act, which accompanies a Quarterly Report (第３四半期報告書). While it references the quarterly report, the document itself is a formal regulatory filing confirming the accuracy of the financial statements for the period ending June 30, 2023. Since it is a specific regulatory filing required by Japanese law to accompany financial reports and does not fit into the 'Interim/Quarterly Report' category itself (which would be the full report), it is best classified as a Regulatory Filing.

四半期報告書－第56期第3四半期(2023/04/01－2023/06/30)
Interim / Quarterly Report Classification · 100% confidence The document is a 'Quarterly Report' (四半期報告書) for Asaka Riken Co., Ltd., covering the third quarter of the 56th fiscal year (April 1, 2023, to June 30, 2023). It contains detailed financial statements, including the balance sheet, income statement, and comprehensive income statement, along with notes to the financial statements. This meets the criteria for an Interim/Quarterly Report (IR) as it provides substantive financial data and analysis for a period shorter than a full fiscal year. 9M 2023

Report Publication Announcement Classification · 100% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act, specifically related to the accuracy of the Second Quarter Report (Interim Report). While it references the quarterly report, the document itself is a formal regulatory filing confirming the accuracy of the financial statements for the period ending March 31, 2023. Since it is a specific regulatory filing required by Japanese law for financial reporting compliance and does not fit into the 'Interim Report' (IR) category itself (which would be the full report), it is best classified as a Regulatory Filing (RNS).
