The Floating Torii of Tenso Shrine serves as a sacred boundary (Kekkai) between the physical and spiritual worlds. Its holiness is amplified by the unique geography of Lake Kinrin; because the lake contains both hot and cold springs, the Torii is often wreathed in a "heavenly mist." This phenomenon is seen as the presence of the water deity, and the gate stands as a symbol of protection over the lake's thermal waters, inviting a sense of deep reverence and spiritual stillness.
