2025年12月期有価証券報告書の提出完了に関するお知らせ
Report Publication Announcement Classification · 95% confidence The document is a brief announcement stating that the company has completed submission of its 2025 fiscal year securities report (有価証券報告書) and has disclosed its fiscal year-end earnings release (決算短信). It contains no financial statements or substantive data itself, merely informs stakeholders of report publication. Under the “menu vs meal” rule, this is a Report Publication Announcement, not the report itself.

内部統制報告書の訂正報告書の提出に関するお知らせ
Regulatory Filings Classification · 85% confidence The document is a brief TSE disclosure notifying investors that the company has submitted corrected “Internal Control Reports” for past fiscal years to the Financial Services Agency (Chugoku Finance Bureau) and summarizing the corrections and remedial measures. It does not contain full financial statements or the body of the internal control report itself, but is an announcement of a regulatory filing. According to the menu‐vs‐meal and certification rules, this falls under a general regulatory announcement rather than the actual report, so it is classified as a Regulatory Filing (RNS).

財務報告に係る内部統制の開示すべき重要な不備に関するお知らせ
Regulatory Filings Classification · 85% confidence The document is a formal notification under Japan’s Financial Instruments and Exchange Act disclosing a material weakness in the company’s internal control over financial reporting and outlining remediation measures. It does not itself contain full financial statements and is not the Internal Control Report (it merely announces its findings), nor is it an earnings release, annual or quarterly report, or other specific report type. It is a compliance/regulatory announcement, thus falls under the general “Regulatory Filings” category (RNS).
