Funabashi circuit is the circuit that there was ever in Funabashi-shi, Chiba in approximately one hour by car from Tokyo. I opened in July, 1965 and was closed down in August two years later. It becomes the Funabashi automatic race track, and it becomes short Oval for gamble motorcycle races now. It is Piero Taruffi to have designed the course. The course is designed to have races by 1.8km, 2.4km, three layouts of 3.1km with flatness.
