Beyond the stone walls of Karatsu Castle, feel the sea breeze. A traditional Japanese Ryokan with views of Karatsu Bay from every room.

Mizuno Ryokan is a traditional Japanese inn nestled beside the stone walls of Karatsu Castle. From every room, you can enjoy panoramic views of Karatsu Bay, with a refreshing sea breeze drifting through. Step through the historic gate of a former samurai residence and head to your ocean-view room. Savor seasonal cuisine featuring fresh seafood from the Genkai Sea and premium Saga beef, thoughtfully prepared to enrich your stay.

  • This was not just a clean Accommodation, but a place that felt like a “second home,” filled with warmth and thoughtfulness.In every corner of the Room, we could feel the host’s care and affection, and throughout our stay we felt comfortable and genuinely welcomed.The meals were also truly outstanding. Each dish was prepared with great care and sincerity—delicious, and an unforgettable taste.We had a truly wonderful time and are sincerely grateful. We would love to visit again.

  • I visited Mizuno Ryokan because I wanted to see the sea at the end of summer.It’s a historic Ryokan, and the building felt like a maze.The ocean scent and the meals were the main highlights for me.The attendants’ service was also very good.The food was outstanding—squid, abalone, spiny lobster, and sea urchin. The quality and portion sizes were perfect for us, and above all, each soy sauce pairing was excellent.You could really feel the head chef’s care in every dish.I’d love to come again even just for the meals.Checkout was completed in our Room,and when we left the Ryokan, no one saw us off. After we passed through the gate, the proprietress came running after us, but it still felt a little lonely.
