“Engrish in Japan” (https://www.facebook.com/groups/EngrishInJapan/) is a very popular Facebook group that collects unique and sometimes very ironic usages of English in Japan. If you speak only English, they are just strange errors. If you understand the Japanese language, some of them are funny. If you are familiar with Japanese culture and customs, a few of them are quite ironic. Highly recommended for students in the Japanese classes.
