With the recent rise of flood risk, the importance of planning to reduce flood risk has become larger. After the amendment of planning law and related law in 2020, the legislation tends to become more strict, however, the efficacy of the amendment depends on how the laws are implemented by local governments. In this paper, we focus on prefecture ordinace which is expected to play an important role to regulate developments considering flood risks. Ordinances of prefectures were surveyed and contents were analyzed to find some good practices although the limited number of prefectures enacted ordinaces related to development regulation for flood risk reduction. Also, some issues related to city planning, which should be addressed by local governments were identified.
