Lunch is not provided. * In addition to the all-inclusive plan (with dinner and breakfast), breakfast-included and no meals included plans are also available.

  • We stayed here as a couple on a trip to Kochi. It was our first time, and what impressed us most was the food. Both dinner and breakfast are buffet-style, with Japanese dishes (including local specialties), Western, and Chinese options—all of excellent quality. Even my wife, who is very particular about food, was delighted. Drinks such as beer, sake (including various local brands), and spirits are also available with unlimited refills, so I can recommend it to anyone who enjoys a drink.We would love to stay again when we visit Kochi.

  • The Room was spacious, and the Onsen was excellent.There was a wide variety of food, and many dishes were delicious.The seating with an ocean view was also wonderful.Due to my mistake, I made a Reservation for one instead of two, but the staff changed it promptly at check-in.All the staff provided very good service.I would like to visit again.Thank you for your hospitality.

    Summer 2026! Limited-Time Dinner Menu

    A special seasonal “Chotaro Paella” that captures the bounty of the summer sea in a single dish.
    Chotaro shellfish (Hiougi scallops), beloved in Kochi Prefecture, are prized for their plump, sweet flesh and rich umami.
    The rice, infused with plenty of savory juices released from the shellfish, delivers ocean flavor in every grain, while the luxurious aroma of saffron enhances the taste even further. Finished with fragrant crispy socarrat for an added textural accent, this authentic paella is satisfying to the very last bite. With vibrant shells adding a splash of color, it’s a gorgeous dish that evokes the summer sea. Please enjoy this summer-only indulgence—seasonal flavors nurtured by Kochi’s abundant waters fused with a classic Spanish tradition.
