下総台地
Shibayama is located in northeastern Chiba Prefecture, about 30 kilometers from the prefectural capital at Chiba and 50 to 60 kilometers from the center of Tokyo. The town is a hilly area, located almost in the center of the Shimōsa Plateau. Narita International Airport is located to the north of the town on the border between Shibayama and Narita. Most airport service facilities are located on the Narita side: however, Shibayama has developed a local industrial base due to the airport's presence, and hosts three major industrial areas. The remainder of the town is agricultural, and much of it is covered with rice paddies and areas of vegetable production. As it lies directly beneath one of the main approach paths to the airport, noise pollution and eminent domain issues have caused it to be a center of anti-airport activism.
