The spider-fauna of Tokiwamatsu Imperial Villa, Tokyo, was investigated in the years 1977-1978 and 2002-2004 mainly by extractions with Tullgren Funnel and Malaise trapping as well as by collecting with hands. About 400 specimens of spiders collected from various places in the gardens of the Villa were classified into 64 species of 22 families. The whole site of the Villa covers at present an area of about 20,000 square meters in Shibuya-ku Ward, in the center of Tokyo. The surroundings of the area were already urbanized in Edo Era since 17th Century and damaged through tea plantation, silk growing and pasturing cattle in the Meiji and the Taisho Era between!882 and 1923. After that, however, the area has been used for the Villa of Imperial Families and the gardens are kept in nature under gardening care. Almost all (97%) of the recorded species are common with those of other green areas in Tokyo city center as the gardens of the Imperial Palace, with the exceptions of a crab spider Lysiteles coronatus and a jumping spider Bristowia heterospinosa. Notes on these spiders and a relatively rare species Brommella punctisparsa (Dictynidae) are given.
