Guntû ガンツウ | Japan Luxury Travel Agency

Operating by Setouchi Cruise, Guntû is a luxury floating hotel in Japan’s Seto Inland Sea since 2017. The ship’s name was taken from the local name of a blue crab indigenous to the Setouchi region, in the hope that like this creature, guntû would become one of the subtle delights of the Inland Sea.

The silver hull that reflects the sunlight and color of the sea contains 19 wood-paneled cabins and cozy common spaces designed by the Japanese architect Yasushi Horibe. Relax aboard this ship resembling a Japanese ryokan that blends into the gentle scenery of Setouchi, filled with special pleasures ranging from a dining experience of “what you want, as much as you want,” the cozy six-seat sushi bar with a view of the sea, and a Japanese confectionary at the Lounge, to the communal baths with hinoki cypress bathtubs and saunas.
