Lake Tōya is said to be the northernmost lake in Japan that never ices (with competing claim by nearby Lake Shikotsu), and the second most transparent lake in Japan. Nakajima Island (not to be confused with another island of the same name in Lake Kussharo) is an island in the middle of the lake which houses the Tōya Lake Forest Museum.
Lake Tōya was called Kim'un-to (キムウン (kim'un) means "in the mountain" and ト (to) means "lake") by the Ainu. In the Meiji era, Japanese pioneers named the lake Tōya after the Ainu expression to ya, which means "lakeland".
The 2008 G8 Summit was held at Lake Tōya and The Windsor Hotel Toya Resort & Spa.
