The Financial Instruments and Exchange Act (J-SOX) was applied to listed companies in Japan from fiscal year 2008 to prevent the repeated accounting scandals and a lack of compliance. However, there is little literature on PMO activities corresponding to J-SOX and besides this is an example of specific industry. NTT Data Corporation became subject to US-SOX (Public Company Accounting Reform and Investor Protection Act) as a subsidiary of the NTT Group, listed in the US stock exchange, as well as to J-SOX as one of listed domestic companies. Deficiencies, pointed out in these audits, may lead to a huge increase in operational cost. In order to prevent deficiencies from occurring, it is necessary to improve company-wide IT control level and to act efficiently. So this paper suggests PMO activities that the IT Control Development Team should implement. The concrete activities to be implemented are the consolidation of in-company rules concerning IT Control, self-check, sharing information and support, and further improvement of PDCA cycle. In consequence of implementation of these activities, the number of relevant audit items has been reduced by about 29%, which has reduced the work within the IT Control Development Team by about 27%.
