Dialect card

Punitive mark indicating a person speaks a non-standard, stigmatized dialect

A dialect card was a type of card used in a punishment system of Japanese regional schools in the post-Meiji period to promote the Tokyo dialect of Japanese in favor of other Japanese dialects and other Japonic languages. A student who spoke in dialect would be forced to wear the card until another student also spoke in dialect, and then it would pass to the new transgressor; the student wearing it at the end of the school day receives corporal punishment by the teachers.
