Karatsu Seaside Hotel

A resort hotel known for its sweeping views of Karatsu Bay. Its location beside Niji no Matsubara, one of Japan’s three great pine groves, offers both seaside scenery and lush greenery.

The hotel has 139 Western-style and Japanese-Western rooms overlooking the Genkai Sea. It consists of two buildings, the West Wing and East Wing. Facilities exclusively for East Wing guests include an open-air observation bath, saunas, and the Rooftop Thermal Bath, a rooftop infinity pool filled with natural hot spring water where swimsuits are required. Guests can relax in the sodium chloride-rich natural hot spring. Another highlight is the distinctive bathing experience. The hotel recommends the Roman-Irish Bath, which combines ancient Roman bathing practices with Irish hot-air bathing. Following a set sequence through the outdoor and indoor baths and saunas provides a deeply relaxing experience.

Dining options are also plentiful. Restaurant GEPPARO serves a buffet of more than 80 Japanese and Western dishes, including Karatsu squid, abalone, and Saga beef. The hotel also has a teppanyaki restaurant, a seasonal summer barbecue restaurant, and a bar. A selection of sake is available as well, reflecting Saga’s reputation as a renowned sake-producing region.
