Improving the environment for business is an important part of the growth strategy of Abenomics. As the goal for this effort, the Abe Administration aims to improve Japan’s rank in the World Bank Doing Business Ranking to one of the top three among OECD. This paper clarifies what it takes for Japan to achieve the goal. By looking at details of the World Bank Doing Business ranking, we identify various reforms that Japan could implement to improve the ranking. Then, we classify the reforms into six groups depending on whether the reform requires legal changes and on political resistance that the reform is likely to face. By just doing the reforms that do not require legal changes and are not likely to face strong political opposition, Japan can improve the ranking to 13th. To be in the top 3, Japan would need to implement all the reforms that are not likely to face strong political resistance. The conclusions, however, are based on the assumption that the conditions in the other countries do not change, which is unrealistic. Thus, Japan would need to carry out all the reforms including those with high political resistance to be among the top three.
