Shimōsa Plateau
The Shimōsa Plateau　covers most of northern Chiba Prefecture. The plateau ranges between and above sea level. While the Shimōsa Plateau has no set boundaries, it ranges roughly south to north from the Bōsō Hill Range to the lowlands of the Tone River, and east from the Edo River west to the lowlands of Kujūkuri Beach. The plateau runs from Funabashi to Katori.
