Overview
Mizuno Ryokan is a purely traditional Japanese ryokan at the foot of Karatsu Castle, with ocean views from every room. From the sukiya-style guest rooms you can look out over Karatsu Bay and its islands, and both dinner and breakfast are served as in-room kaiseki courses featuring seafood from the Genkai Sea and Saga beef. There is also a communal bath (Matsu-no-yu) renewed in 2024, and rooms with an in-room hinoki cypress bath. Welcomed by a samurai-residence gate, this castle-town ryokan lets families spend an unhurried stay together.
Mizuno Ryokan is a purely traditional Japanese ryokan standing just beside Karatsu Castle in Karatsu, Saga Prefecture. Passing through the samurai-residence gate that still carries the atmosphere of the Keicho era, you find a stone-paved corridor and a waiting area arranged with seasonal flowers, where the calm pace of a castle town unfolds. All 8 rooms have ocean views, looking out over Nishi-no-hama beach and Karatsu Bay, with islands including Oshima, Torishima, and Takashima, home to Hoto Shrine.
Guest rooms
Purely Japanese-style architecture built in the sukiya style. The main building's 10-tatami-mat 'Matsu,' 'Take,' 'Ume,' and 'Hime' rooms all have an in-room bath, and the 'Hime' room in particular has an in-room hinoki cypress bath overlooking the sea of Karatsu. The main building's 20-tatami-mat 'Shiro' and 'Nishi' rooms, the 20-tatami-mat 'Yuri' room ('Kanpu-tei') in the old wing, which is registered as a Tangible Cultural Property, and the main building's 6-tatami-mat 'Naka-no-ma' with its beautiful ajiro (woven bamboo) ceiling each have their own character. Because every room is a Japanese-style tatami room, families with crawling-age babies can relax safely on the tatami.
Bathing
The communal bath 'Matsu-no-yu (Sora / Kaze),' renewed in 2024, incorporates pine trees - a symbol of Karatsu - into its decor, finished in granite and pine paneling for a calm space. Guests can view pine trees through the windows, and at night the illuminated scenery offers a dreamlike view. It is heated bath water rather than an onsen, and the bath is separated by gender. Some rooms also have an in-room bath, convenient for families who want to bathe without worrying about other guests.
Meals
Both dinner and breakfast are served in your room. Dinner is a kaiseki course centered on seafood from the Genkai Sea, served course by course starting with small dishes. The Saga beef used is Grade 5, and the tableware used to present the dishes is mainly Karatsu ware and Arita ware. Live tanks in the ryokan hold spiny lobster, squid, fish, and shellfish, reflecting a commitment to freshness. In-room dining, where you don't need to worry about a shared dining room, is a reassuring point for families with small children.
Rental items and family facilities
A step stool for children and a baby chair (a chair for young children) are available for rental, useful at the washstand or during meals. Bicycles and a desk fluorescent lamp are also available for rental. The library has a book corner with a sofa to relax on.
Private villa 'Nami Shizuka' (whole-building rental)
A private, ocean-view villa that opened at the foot of Karatsu Castle. In its spacious, open interior, your family can spend time together without worrying about night crying or fussiness (the villa, including its terrace and balcony, is completely non-smoking).
