Supporting Trading Participants

JPX-R posts Inspection Case Studies on the Target. They contain cases where trading participants had been found to be in violation of laws and regulations, cases where trading participants should make improvements to prevent future risks, and the relevant laws, rules, and regulations.
JPX-R hopes that they will serve as a reference for developing systems to prevent similar violations.
