There is a bus to the station, and you can also take a bus or walk to it. Sand steam + hot spring is 1080 yen, pure hot spring is 610 yen. After the shower, put on a dedicated bathrobe to the beach. The bath union lets you lie down and bury you with black sand and tell you that it takes 10 minutes. In fact, it is really difficult to stick to more than 10 minutes. After getting up, go indoors and soak in the hot springs again, and then come to the lobby for a milky ice cream, which feels really great.
