Though technically not in Osaka, this is one famous onsen we couldn’t leave off the list which is only an hour from Osaka.

Arima Onsen hosts three different types of hot spring, the Kinsen or the Golden Hot Spring and two different types of Ginseng or the silver hot springs. The Kinsen is named as such mainly because the yellow-colored water comes from iron and salt. The Ginseng Spring is colorless; hence it was aptly named as such.
