Abstract
The author discussed the contribution and aims of climatology to the geoecological research on the Japanese mountains. Firstly the characteristics of the Japanese mountains was presented. The spatial scale of it is largely different from the great mountain systems such as the Alps, the Andes, etc. The features of the mountain climate of Japan were then discussed. One local feature of the winter monsoonal wind and its precipitation is distinguished, whereas the synoptic scale pressure systems are considered to be repeating event-maker. Lastly two ways of contribution were presented: the one intensive field observation and the other is to construct or tune up a high resolution atmospheric model for complex terrain.
