“The Yahiko sky line”, the mountain road was constructed aIong the western slope of the Mt. Yahiko (600m high) in 1970. On the 24th April of 1979, many slope failures of road cutting and small debris follows occurred along the road due to locally destructive heavy rain fall as shown in Fig. 1. This paper deals with the relations between the bed rock-and surface-geology and types of the slope failures, and also with the consideration on the preservation of the road cutting. The result can be summarized as follows: 1) Geology of the Mt. Yahiko consists mainly of Miocene intrusive rocks, pyroclastics and Shale as shown in Figs. 3 and 4. 2) Along the road, various pyroclastics, intrusive rocks, shale, landslide debris and talus cone deposits are exposed at the road cutting as shown in Fig. 5. 3) The slope failures of the cutting were concentrated to the cutting made of the shale, landslide debris and talus cone deposits, in relations of the difference of physical properties of these rocks and deposits. 4) On the basis of our study, some recommendation are presented from the preservation of the slope of the road cutting in this area.
