Lake Kussharo: A Spectacular Lake Embraced by Sea Clouds

Lake Kussharo, Japan’s largest caldera lake, captivates visitors with its majestic natural beauty. From early summer to autumn, the Tsubetsu Pass Observatory offers views of a sea of clouds enveloping the lake and surrounding mountains, creating a dynamic and fantastical landscape. On clear days, the transparent lake surface reflects the surrounding mountains, highlighting nature’s mystique. The
lakeshore features unique “sand baths” where digging into the sand reveals natural hot springs, providing visitors with an extraordinary hot spring experience.
