I recently visited a department store near Kyoto station, hunting for a power converter so I could charge my laptop. The store was split into 7 floors, each selling different products. Most were immediately recognizable: “Men’s Fashion,” “Women’s Fashion,” “Books,” and so on. One floor, however, was mysteriously labeled “subculture.” Of course, I had to check it out. As expected, the floor was full to the brim with anime, manga, trading cards and arcade games.
