One of the first things you notice when you start living in Japan are all the cool prefectural flags (Wiki).
One of the first things you notice when you have lived in Japan for a while are all the funky prefectural flags. From Tokyo’s anus flag (3Yen / 2006-11-14) to Yokohama, Kanagawa’s limp dick flag (3Yen / 2006-11-14) Japan is full of unfortunate designs.
There is also the problem with inconsistencies of the designs and colors of each prefecture’s flag(s). Many Japanese prefectures have more than one “official” flag. There are traditional flags, sports flags, “symbol” flags, and even official “communicative” flags.
