Private-use hot springs: Yes
Rooms with open-air baths: Yes
Known for its “Hell Tour” of eight multi-colored hot springs, Beppu produces the most hot spring water in the nation, and is perhaps Japan’s most famous onsen. At Hotel New Matsumi, sea, spa and sky combine as you overlook the Beppu Bay in all its glory. Commanding views of the ocean can be found on the top floor outdoor onsen as the soft breeze caresses your face, or from many of the rooms where you can conveniently dine kaiseki style on the freshest foods the bay has to offer. For a private dip, submerge yourself in the sodium bicarbonate saline spring waters in the private rock bath, or the open air ceramic (porcelain) baths attached to your room.
Take the JR Limited Express Sonic train from JR Hakata Station to JR Beppu Station. A 10-min. walk from the station.
