The Aesthetics of Interchange Love Hotels. Toyoshina, Azumino, Nagano, 長野県 Japan. From superheros to victorian lace, the aesthetics of love hotels are a cultural phenomena completely unique. Part theme park, part members club, part underground casino, part sex toy club … Love Hotel design is completely it’s own. This love hotel, Hotel Astro, in rural agricultural city, Toyoshina, and directly off the interchange, is one of my favorite examples of the outrageous themes in Love Hotel design. Each room is super hero themed and individual garages are provided for hotel guests so that cars are not visible to the public.
