It's amazing what Japanese pachinko machine manufacturers will license in order to put media characters into pachinko parlors. Previous licenses have included Urusai Yatsura, Lupin III, Samurai Champloo, among many others.
This is a poster advertising new machines at a local parlor. The poster was on the wall of a train station on the Keio line. Even Jack Bauer, from the U.S. TV series "24" can look cute in "chibi" form.
