Win a holiday to Japan - Yubatake at Kusatsu Onsen for two, everything included: business flights, 5* accommodations, transfers and city passes as well!
Japan always worth a visit! Yubatake - Kusatsu Onsen has the highest output of healing hot spring water in the world. Its pH value is 2.1 which means it has an outstanding bactericidal component and is the best for skin.
Among hot springs, Kusatsu (located in Gunma prefecture) is considered one of the very best. In fact it has been ranked as the number 1 hot spring by Japan's top travel agents for many years. Aside from the astounding volume of hot spring water the makeup of the water is also unique; has powerful antibacterial properties and is considered highly therapeutic by hot spring experts. I personally found it to be thoroughly relaxing and my skin was feeling great and looking better after just a couple of soaks.
