The northern Hida Mountains located in central Japan consist of high-relief mountain ranges. Previous studies have reported on the distribution of the glacial topography and explained the landform development caused by glaciers in this area. On the other hand, the authors published the “Landslide Geomorphological Map of the Northern Hida Mountains （1：25,000）” in 2008. This map revealed the landslide distributions and glaciated topographies. It showed that not only glaciation but also landslide activities are important contributors to geomorphological developments in this area. However, because this map was an internal document, its circulation was limited to narrow range of research communities. We have now received the opportunity to republish this map for a wider audience through this journal. This paper explains the methods and criteria for geomorphological mapping and shows the characteristics of landslide distribution and landslide development. The following conclusions are derived from this study：（1）Many landslide topographies are distributed in the study area. （2）The landslide topography is divided into three types：Types A and B were formed by rock creep, with Type B being formed by a more developed phenomenon than Type A. and Type C was formed by rock creep and slide. （3）Some glaciated slopes and periglacial slopes were dissected by landslides after glacial and periglacial processes, respectively. Furthermore, large-scale landslides occurred before the Last Glacial Period. Landslide activities are the main processes occurring through a glacial period to a interglacial period.
