The objective of this paper is to clarify the environmental performance of the traditional houses in mountain region of Japan. On-site field surveys regarding outdoor climate were carried out in two rural settlements. Indoor climate was measured in five traditional houses located at both settlements for one year. One hundred and five residents answered questionnaire about their life style and living environment in summer and in winter. Mountain topography and settlement's location affected the air temperature distributions over the settlements. The moderate heat island was found in Ogimachi both in winter and in summer. In traditional houses with thatched roofs, a relatively small daily temperature range and long phase difference were represented in indoor air temperature fluctuation. These phenomena result in heat capacity of the traditional houses and evaporative cooling from a thatched roof. Shimura et. al. proposed the comfort zone for the Japanese which covered higher temperature and higher humidity than that for Europeans and Americans. Japanese traditional house can fairly control its indoor climate in summer to be suitable for the Japanese.
