取締役会の実効性評価結果の概要について
Governance Information Classification · 91% confidence The document is a summary of the Board of Directors’ effectiveness evaluation, detailing governance practices, board composition, evaluation methods, and future governance improvements. It is not announcing director changes or share transactions, nor is it an annual or interim financial report. This fits the Governance Information category (CGR), which covers reports on internal rules, board structure, and governance practices.

訂正発行登録書
Capital/Financing Update Classification · 85% confidence The document is a “訂正発行登録書” (corrected issuance registration statement) filed to the Kanto Finance Bureau under Japan’s Financial Instruments and Exchange Act. It details the correction to the original bond issuance registration, specifies issuance amounts, dates, and legal references. This is not an annual or interim report, nor a simple publication notice, but a regulatory filing related to the company’s capital and financing activities (specifically bond issuance). Therefore it best matches the "Capital/Financing Update (CAP)" category.
