The observations on the indoor-climate of the Sangatsudo (wooden building built about 1200 years ago) and Daibutsuden (the biggest wooden building in the world) of the Todaiji Temple and of the Shinyakushiji- hondo (wooden building as old as the Sangatsudo) as well as their outdoor-climate were made the aide of weekly type thermo-hygrographs for the periods extening from November 1968 to November 1969. Main results obtained in this study are as follows : Sangatsudo, Shinyakushiji-hondo and Daibutsuden showed annual mean values of 14.7°C in temperature and 72% in humidi ty, 15.4°C and 71%, and 14.3°C and 71%, respectively. These annual mean values of about 15°C and 70% which appered in these buildings and also in many temple buildings in Nara City and its vicinity may be considered a standard condition for the preservation of Japanese antiquities. In those months of July, Augst and September, since some undesirable conditions of high temperature-humidity which are harmul for old materials are apt to appear in Sangatsudo and Shinyakushiji-hondo, we must pay attentions to protect antiquities from mold and noxious insects.
