If you decide to spend your vacation at a 4-star hotel in Mizunashi, you'll typically find plenty of amenities to keep you relaxed, such as a gym, pool and restaurant. You can experience high-quality service and upmarket accommodations. Go for a 5-star hotel and you'll have access to a few more bells and whistles — think on-site spas, around-the-clock concierge and nightly turndown services. You'll most likely get more amenities and exclusive services at a 5-star retreat, but both are awesome options for luxury guests.
