Shibukawa is in the northern extremity of the Kantō plains of central Gunma Prefecture, encompassing the juncture of the Tone River and Agatsuma River. It is about from Tokyo. To the west is Mount Haruna, and to the east is Mount Akagi. To the north are Mount Onoko and Mount Komochi. The Tone River flows from the north (between Mount Akagi and Mount Komochi) southward through the city, while the Agatsuma River flows from the west (between Mount Onoko and Mount Haruna), merging with the Tone River near the center of the city.
