It features a variety of baths and a stunning night view where the past and present blend together, bathed in neon lights.

Passing through the torii gate... Though it should be night, it is not dark. Purple clouds flow slowly across the sky, and countless lights twinkle along the mountainside. The entire hot spring town is enveloped in a glow like scattered stardust, and the steam takes on pale shades of pink and indigo as it melts into the night sky.
