“Health lands” were Japan’s super-sized bathhouses: onsen, saunas, restaurants and nap rooms stacked into one big box, built for families and truckers alike. This one, sitting along the route between Nara and Mie, served the passing traffic until the business dried up, and it has been decaying ever since.
It is also one of the more genuinely unpleasant haikyo I’ve visited: dark, wet, and full of asbestos. If you ever find yourself inside, don’t linger, and consider a proper mask non-optional. The scary atmosphere, at least, comes free of charge.
