Asahikawa Prison introduced the world to Katakkuri-chan in 2013, Katakkuri-chan both as a boy and a girl, with the gal sporting a violet dress and green sash resembling the lovely flower they're named after while the guy is dressed like a prison warden to represent the crushing regime they're trying to put a happy face on.
And these flowery buddies have quite the task ahead of them. Asahikawa Prison has repeatedly been compared to a Soviet gulag. This is a place where one prisoner was once kept in solitary confinement for 24 hours a day for 13 years for making "antiestablishment remarks." This guy was alone for so long that his lawyers actually thought he was losing the ability to speak. But just trying staying mad at this little fella/gal.
"Awwww okay, you can lock me up."
Katakkuri-chan also appears on a line of coasters and bookmarks, which the inmates themselves have to make. He/she now also greets new prisoners as they're brought, which must be about as comforting as being punched in the balls by a Teletubby.
