Abstract
The race horse ranches are historically located and developed in specific regions in Japan. This study has been made on localization of the race horse ranches, mainly from the view point of topographical and geological aspects and make clear common conditions of these localized ranches. Results obtained are as follows. A. Almost all the ranches located and developed regions are classified four lotations as follows ; 1. Dissected plateau covered with volcanic ash soils. 2. Frequently flovd suffered areas. 3. Tectonic terrace e.g. large coastal terrace zone. 4. As recently developed region, hilly or at the foot volcano regions covered with volcanic ash soils. B. Agricultural conditions common to above mentioned four locations, all of them are histrically unproductive and barren lands.
