TSE deeply apologizes for the inconvenience caused to many investors and other market users due to the arrowhead cash equity trading system failure on October 1, 2020.
TSE has identified the direct cause of the failure and has implemented measures to address the issues in the system by October 5. As well, a report was published on October 19 about the cause of the failure and measures to put in place to prevent a recurrence.
JPX has established a "System Failure Investigation Committee" comprised of independent outside directors to increase the effectiveness of various measures put in place to prevent similar incidents.
In addition, with the aim of considering how TSE should develop its responses to system failures and its rules and regulations to prevent recurrences of similar incidents, TSE has established a "Council for Recurrence Prevention Measures" comprised of market users, and has held its first meeting.
