A modern Japanese-style Ryokan has opened in the elevated villa area of "Millennia Katsuura" in Minamiboso, reminiscent of a tropical resort. Spanning a total area of 3,000 tsubo, it features a sunny and spacious garden terrace, a pool (for light-up viewing only), a pet hotel, and a dog run. Enjoy heartwarming holidays always together with your beloved dog.

  • This was my first time visiting Katsuura, Chiba Prefecture, and I stayed for one night. I was completely satisfied with everything—the Room, the meals, and the staff’s service. At night, I even saw a shooting star from the balcony. It is a quiet Accommodation where I could relax and unwind. Thank you for the wonderful memories.

  • This Accommodation is perfect in both facilities and service. Everything is spotless, and it was truly impressive how the staff provide heartfelt hospitality while maintaining a comfortable sense of distance from guests. I felt they must place great emphasis on staff training. Dinner was a full-course Japanese meal featuring local ingredients, with abalone and splendid alfonsino as the highlight. The seasoning was natural and brought out the best of each ingredient. Both dinner and breakfast were generous in portion, but everything was so delicious that I finished it all. Thank you for making such wonderful summer memories for us.
