Kashikojima is a gentle island where the quiet and beautiful sea stretches out, and time seems to stand still under the soft light. Our Property is located on a hill with a great view. It does not offer trendy luxury or flashy newness. Instead, it is surrounded by the sea, greenery, and the quiet nature where time flows slowly. It is a Property where you can spend a slightly different time than usual. Meals are served in your Room, allowing you to enjoy a relaxing and private gathering. Experience the great nature of the national park, the tranquility overlooking Ago Bay, and the luxury of doing nothing. Please visit "Ise-Shima National Park Kashikojima's Property Michishio."
