Soil samples for a TULLGREN funnel were taken from a depth of 0-5 cm on each of twenty two sampling dates during 1971-1975. Faunal makeups of soil microarthropods were similar among three habitats-the forest (the natural forest withe Quercus and Miscanthus), the grassland of plough cultivation and the grassland of hoof cultivation. In each habitat, the majority of total population was Acarina and Collembola. Especially Acarina was the largest, being 85% in the forest, and 63-64% in the two types of grasslands. Changes of total and Acarina populations were peculiar to each habitat. Mites of suborder, Pro-, Meso-, A- and Cryptostigmata were obtained, and Meso- and Cryptostigmata were the main acarine groups in each habitat. The number of oribatid species obtained from each habitat was 27(in 1971) and 14 (in 1975) in the forest, 12 and 4 in the grassland of hoof cultivation and 9 and 4 in the grassland of plough cultivation. The similarity in species composition of Cryptostigmata evaluated by using the C_λ-index. It was found that the degree of similarity in species composition was lower between the forest and the grassland than between the two grasslands, especially in 1975.
