Kusatsu Onsen is one of Japanese leading hot-spring resorts.

The quality of its spring water which flows from one of the countrys three major springs - is widely known. Centered around Yubatake (the symbol of Kusatsus abundant hot water), visitors can experience a variety of baths free of charge.

This acidic hot spring has high bactericidal properties, and is said from ancient times to cure diseases that doctors have given up on. It is recently attracting attention not just for its positive health effects, but also for maintaining beautiful skin for women. Not only that, it also promotes metabolic changes, which is ideal for those who want to lose weight.

Eating meals prepared Japanese-style is one of the most memorable moments of staying in a Japanese-style hotel. We use delicacies and seasonal ingredients of the Kusatsu region and prepare each dish with special care and attention. We take 4 to 5 trips to deliver the dishes so that you can eat warm and cold dishes at their best temperatures.
