Ikaho Onsen (ɍۉ) is a hot spring town located on the eastern slopes of Mount Haruna. Known for its reddish brown, iron-laden thermal waters, Ikaho Onsen joins Kusatsu, Minakami and Shima Onsen as the four most famous hot spring resorts of Gunma Prefecture.

The atmospheric old town area of Ikaho centers around the 300 meter long stone stairs which lead up through the middle of town and are lined by ryokan, old fashioned game arcades and shops.

A few kilometers outside of Ikaho stands Mizusawa Kannon, a popular temple, well known for the udon noodles sold at restaurants along its approach. Mount Haruna with its beautiful caldera lake can also be easily combined with a visit to Ikaho.
