Abstract

We reclassified soils from National Land Survey (NLS) to Unified Soil Classification System of Japan (USCS), and compared these soil maps. Soils were reclassified used with soil columnar sections of NLS, at two research areas-Hamaoka-town in Shizuoka Prefecture and Asahi-village in Yamaguchi Prefecture. Many soil classes of NLS were classified into expected Subgroups from a central concept of USCS, but several soil classes were classified into the different soil classes. The reason was because the soil derived from eolian sand is not classified into Fluvic soils according to USCS and thickness requirements of the alluvial soil were different. About soil map, there is a great difference between NLS and USCS at the mountain forest area, USCS map is rough. Because, USCS does not have the classification rule of catena on Brown Forest soil, but NLS has. To express the Catena on a scale of 1/50,000 was not suitable, and it is considered that the Subgroup level of the USCS is proper on a scale of 1/50,000.
