Filing Released Lang Actions
発行登録追補書類（株券､社債券等）
Capital/Financing Update Classification · 1% confidence The document is a Japanese securities issuance registration supplementary filing (“発行登録追補書類”) detailing the terms of a new issuance of share subscription rights (新株予約権証券), the issuance amount, use of proceeds, and related financing and capital structure details. It is not an annual or interim report, audit report, AGM materials, or earnings release, nor is it a brief fact sheet or investor presentation. It is a detailed regulatory filing on a financing transaction. Therefore, it best fits the Capital/Financing Update category.
2026-04-16 Japanese
発行登録追補書類（株券､社債券等）
Share Issue/Capital Change Classification · 1% confidence The document is a Japanese 発行登録追補書類 (“Issuance Registration Supplementary Document”) filed with the Kinki Finance Bureau, containing detailed terms of a third-party allotment of new shares, the amount to be raised, issuance conditions, use of proceeds, lock‐up agreements, and information on the allottee. It is not an earnings release, annual report, or management announcement, but a direct notification and documentation of a share issuance (capital change). Therefore it falls under the “Share Issue/Capital Change” category.
2026-04-16 Japanese
訂正発行登録書
Share Issue/Capital Change Classification · 1% confidence The document is a Japanese “訂正発行登録書” (Corrected Issuance Registration Statement) filed with the Kinki Finance Bureau, detailing the registration of a new share issuance (equity program of up to 4,000,000 common shares, amount limits, effective dates) and correcting a previous filing. This clearly relates to the issuance of new shares and a capital change rather than an annual or interim report, earnings release, or AGM materials. It therefore falls under Share Issue/Capital Change (SHA).

発行登録書（株券､社債券等）
Share Issue/Capital Change Classification · 1% confidence The document is a detailed “発行登録書” (securities issuance registration statement) filed with the Kinki Finance Bureau, describing a multi-tranche issuance of new ordinary shares and stock acquisition rights under an Equity Program Agreement, including issuance schedule, conditions, pricing, allocation to CVI Investments, uses of proceeds, and related terms. This is not an annual or interim report, earnings release, or a notice of vote—it is a formal share issuance/capital change filing. Therefore it best fits the “Share Issue/Capital Change” category (SHA).

発行登録書（株券､社債券等）
Share Issue/Capital Change Classification · 1% confidence The document is an “発行登録書” (Issuance Registration Statement) filed with the Kinki Finance Bureau under the Financial Instruments and Exchange Act. It provides extensive details on the planned issuance of new share acquisition rights (warrants) and underlying equity, including issuance amounts, conditions, schedules, usage of proceeds, and registration details. This is not a routine financial report, earnings release, or meeting materials, but a regulatory filing specifically relating to a new share issuance program. It clearly falls under “Share Issue/Capital Change” (SHA).

確認書
Regulatory Filings Classification · 1% confidence The document is a 'Confirmation Letter' (確認書) filed under Article 24-5-2, Paragraph 1 of the Financial Instruments and Exchange Act of Japan. It serves as an officer certification regarding the accuracy of a semi-annual report. According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations, even if they reference a specific report type (like a semi-annual report), should be classified as Regulatory Filings (RNS) rather than the report itself.
