Rikka Rikka Yu is a day-use onsen in Okinawa built in the style of a neighborhood bathhouse. It has an outdoor bath and a few small saunas, and shampoo, conditioner, and body wash are provided. On a weekday around 2 p.m. it was not crowded and was easy to use at a relaxed pace. There is no Korean signage, which makes the usage instructions inconvenient.
