TSE to Revamp TDNET with AI by Summer 2027—Ending the "Disclosure Hell"

The Tokyo Stock Exchange plans to overhaul TDNET, the timely disclosure information service that listed companies use to publish material facts, as early as summer 2027. The new system will introduce AI functionality that judges whether disclosure is required and whether content is adequate or excessive, and automatically generates filing templates. The exchange aims to dramatically reduce the administrative workload for companies while creating an environment in which investors can quickly access accurate information. The initiative is drawing attention as a direct response to the chronic burden that has led listed companies to describe their disclosure obligations as "disclosure hell."

The development is emblematic of a broader diversification of corporate strategies during a global corrective phase in the EV transition.
