On February 20, 2006, Ikaho, along with the villages of Komochi and Onogami (all in Kitagunma District), and the villages of Akagi and Kitatachibana (both in Seta District), was merged into the expanded city of Shibukawa.
Situated on the slopes of Mount Haruna, an extinct volcano, Ikaho is well known for its hot springs.
Ikaho is 2.5 hours from Shinjuku by express bus, and can be easily enjoyed on a day trip from Tokyo[1]
Ikaho Onsen is one of Gunma's 4 large onsen. This makes it one of the main onsen locations in Japan.
The onsen locations are usually open during weekdays, from 09:00 AM to 06:00 PM[2]
Ikaho Onsen has been called Kogane-no-Yu (The Golden Waters), but the waters used to be clear and colorless. However, due to the iron content, they turned dark brown when in contact with the air. They are also known as Kodakara-no-Yu (Child Waters) since they tend to be mild, warm the body from inside and are popular with women.[3]
