Kantō Plain
Futtsu is located in the southern part of Chiba prefecture, about 40 kilometers from the prefectural capital at Chiba and 40 to 50 kilometers from the center of Tokyo. It is on the southwest coast of Bōsō Peninsula, facing the Uraga Channel at the southern end of Tokyo Bay. Cape Futtsu protrudes into Tokyo Bay, and the coastal areas are part of the Minami Bōsō Quasi-National Park. Although considered to be within the Kantō Plain, inland areas of the city are hilly.
