Abstract
Distribution of Buddhism in Japan has been studied by Mochizuki (1930), Fujii et al. (1963), Fujii (1963), and Kitamura (1994). Prewar annual statistics by prefecture and denomination are hardly utilized as research material. Regional division map by denomination in Fujii et al. (1963) is found meaningful as a way of analyzing the collected data. This paper tries to modify it and make another map based on a prewar material so that it can compare between a present and a past distribution. Some changes can be pointed out as a result.
