  • Tokyo Stock Exchange (TSE) has measures in place to halt trading when necessary in order to ensure fair price formation and investor protection. Trading is halted when information arises that may have a material effect on investment decisions and the details of that information are unclear or TSE deems it necessary to make the content of the information known, or when trading conditions are deemed abnormal. After the suspension of trading in the case of information that may have a material effect on investment decisions, as a rule, trading will resume 15 minutes after the issuer of the security discloses the information and TSE confirms this disclosure.
  • The list of issues for which TSE has halted trading is published on the below page.

Please refer to the below page and Chapter 4, Section 2 of the Securities Listing Regulations for details.

  • JPX has formulated an IT Master Plan with the aim of clearly communicating its direction and strategy on IT internally and externally, and to drive business by aligning management and IT policies. As indicated in the plan, JPX aims to promote initiatives in the two categories of "areas needing steady progress" and "areas needing swift responses" in an integrated manner from a system services perspective, under a new organizational structure that includes JPXI. To achieve this goal, we are continuously striving to further improve our multifaceted fault tolerance and resilience, including the construction of a remote backup system at the Kansai secondary data center, while also taking on the challenge of flexibly and proactively providing new services through expansion of system services and use of information resources. To accelerate these efforts, we are also focusing on the development of human resources with expertise in both digital and business fields, as well those with specialized knowledge and skills.
