"For true haikyo enthusiasts, part of the thrill is the history behind the place, and witnessing the blurring line between natural and man-made worlds as structures are slowly overtaken by plants and the elements. Japan has no shortage of places that fit this description, so it’s no wonder that haikyo has taken off here. Most resort areas in the Japanese countryside have their share of once-extravagant bubble-era buildings that have been left to decay. You could even venture to say that there is something very Japanese about seeing these man-made objects returning to nature: trees growing in kitchens; vines swallowing roofs; storms washing away years of paint; and so on. Haikyo could almost be seen as a form of industrial wabi sabi. (((Or industrial mono no aware, more like.)))
