An exhibition hall where you can experience the Okhotsk winter year-round, with views of the Shiretoko Mountain Range from the Mt. Tento Observatory, designated as a national scenic beauty.

One step inside the building, the drift ice experience room kept at minus 15 degrees awaits. In the room lined with real drift ice, cold air pierces the skin, and through the sensation of breath freezing white, you can experience the Okhotsk severe cold with your whole body. Touching the drift ice, the coldness and hardness transmitted to your palm evokes the journey of ice that has drifted from distant seas. In the aquarium, clione called "angels of drift ice" swim with their transparent bodies swaying, and balloon lumpsuckers and snailfishes with their round forms and adorable appearance soothe visitors.

From the attached Mt. Tento Observatory, a 360-degree panorama including the Okhotsk Sea and the Shiretoko Mountain Range, a World Natural Heritage site, spreads out. The view from this observatory is a valuable scenic beauty designated as a national cultural property. You can overlook the magnificent nature showing seasonal expressions - mountains of fresh green in spring, the brilliantly blue sea in summer, land dyed in autumn colors, and the sea covered white with drift ice in winter. The experience of gazing at the great nature of Okhotsk spreading below while receiving the cold wind is deeply engraved in visitors' hearts.
