Abstract: The author found that earthy mounds develop in some areas of northern Hokkaido, especially on the terraces along the Okhotsk sea. These mounds are semiellipsoidal in shape and very similar to so-called earth hummocks. The mean hight of the mounds is 58.8cm at Ashino, Sarufutsu and 48.5cm at Hamatonbetsu, respectively, and the mean ratio of the long axis to the short axis is 1.59 for the former case and 1.62 for the latter.These mounds are distributed in the direction from NW to SE in the both areas.The micromorphological features of the core sample did not show any fluidal structure and ped distribution signed fragmental structure. With regard to the genetic soil type, the soil profiles of these earth hummocks are similar to acid brown forest soils or pseudogley soils.
