Mizuho is a city located in central Japan within the Gifu Prefecture. Situated near Nagoya, it lies along the Kiso River at the confluence of the Ibi and Nagara Rivers, an area known for its fertile plains. The city was established in 2003 through the merger of the towns of Sunami and Hozumi, making it one of Japan's youngest municipalities with a population of approximately 56,388.
The regional economy is primarily supported by rice and vegetable farming, with Mizuho persimmons—often dried as a winter snack—serving as a local specialty. The city is also recognized for traditional washi (handmade paper) production in local workshops. Notable cultural events include the annual Sunami Fire Festival, which features large torches carried through streets to pray for safety and good harvests, and the Kiso River Fireworks Festival held during the summer.
Historical landmarks in the area include the Hozumi Castle Ruins, which contain remaining earthworks and moats from the feudal era. Mizuho is accessible via the JR Central Line and serves as a practical base for travelers exploring the historic Nakasendō trail and the Kiso Valley.
