Official website Kumamoto Prefecture page

Hikawa Town faces the Yatsushiro Sea in central Kumamoto Prefecture, and the whole town lies on the Yatsushiro Plain. Many kofun (ancient burial mounds), such as Ono-no-Iwa Kofun and the Nozu Kofun Group, remain along the Hikawa River, which forms the border with Yatsushiro City. Upstream is Tategami Gorge, carved by the river, and Miyahara Sanjingu Shrine also stands here.
