Insider Trading Publication Fields

FIEA Article 166 is the public statutory route for company-insider insider-trading restrictions. Japanese Law Translation materials define Publicized through Cabinet Order-specified publication measures or public inspection of specified disclosure documents under Article 25 when the fact is stated in those documents.

JPX’s TDnet page states that disclosure through the Company Announcements Disclosure Service / 適時開示情報閲覧サービス completes legal publication measures for material facts and certain tender-offer facts. The same page states that TDnet public postings are visible on the public disclosure service for 31 days including the disclosure date, while Listed Company Search covers past disclosure materials for 10 years.

Legal Publication and Practical Information Gap

The statutory publication route is tied to the FIEA / Cabinet Order publication-measure framework and TDnet publication-measure field. JPX insider-trading public materials also record a practical information-gap note for the period immediately after a formal public announcement. This field is recorded as a conduct / fairness note, separate from the statutory publication-measure field.
