Using the air temperature records observed at 290 stations and the precipitation records at 350 stations, a climatic division was made from the mesoclimatological viewpoint. The method employed was made from the mesoclimatological viewpoint. The method employed was same to the previous paper on the climatic division of Kanto District, which was appeared in the Annals of the Tohoku Geographical Association vol. 19, No. 4, 165-171, 1967. Figs. 1 and 2 show the divisions by air temperature and precipitation respectively. They were superimposed into a map as giving a climatic division in Fig. 3. Chugoku District was divided into five major areas and 35 subareas and Shikoku District four major areas and 27 subareas. Climatic characteristics for each subareas were described in the text.
