About us


We[a] offer a superlative waterfront experience and opportunities to relax and enjoy the natural beauty of Japan’s greatest lake, Lake Biwa. Our members, including Marina and Yacht Club members, can choose the delightful, premium-quality experience that suits their mood that day.


Connecting directly to Setre Marina Biwako, the clubhouse features a distinctive curved roof and is built with natural materials from Shiga Prefecture such as wood, soil, and reeds. The building beautifully incorporates the natural phenomena of light, water, wind, and sound, letting visitors enjoy the beauty of Shiga to the fullest. When the wooden doors are opened, the breeze from Lake Biwa blows in, and rainwater from the roof is used to nurture a biotope. All outdoor spaces are topped with rooftop gardens, and guests can immerse themselves in the grandeur of Lake Biwa and its environs even while indoors.
