Japanese activities related to radio astronomy in Antarctica are briefly reviewed.

The Japanese base, Showa, is located on the coast and is based on rocks rather than ice. A 10 metre diameter microwave antenna has been built at the Showa station and a series of VLBI experiments have been made between the Showa base and a station in Japan in 1988–1989. The experiments have been geophysically motivated and an accurate measurement of the location of the Showa base was determined relative to Japan, which has a well determined position relative to other continents.
