Study on the community structure of ants was made at the Institute for Nature Study in Minato-ku, Tokyo, Japan. Thirty-six species belonging to 20 genera of ants are recorded : four species in the subfamily Ponerinae, 17 species in Myrmicinae, and 15 species in Formicinae. Compared with other areas in the metropolis of Tokyo, this area has large number of ant species. However, nest densities of forests in this area were significantly lower than those of the natural or semi-natural forests in warm temperate regions of Japan. The dominant or common species were Paratrechina flavipes, Strumigenys lewisi, Lasius japonicus and Pheidole fervida in the forests and Formica japonica, Lasius japonicus, Pheidole fervida, Paratrechina flavipes and Strumigenys lewisi in the road sides. Two dominant species, Lasius japonicus and Pheidole fervida, were inhabited both the forests and road sides. Paratrechina flavipes was the most dominant species in soil or leaf litter layer of the forests studied, providing 46% of the total number of nests discovered. The number of ant nests excluding arboreal species in this area were estimated ca 340,000.
