The end credits for each episode include brief animations of the original comic strips, with dialogue appearing in word balloons. Since November 1991, after the closing credits and the next episode previews, each show has ended with a janken match between Sazae and the viewers at home, in which Sazae holds up a sign representing one of the appropriate hand gestures. From 1969 until October 1991, Sazae ended each episode by tossing a bean or rice cake in the air and catching it in her mouth. Fuji Television switched to the janken match after doctors at Tohoku University Hospital and the National Center for Child Health and Development raised concerns that children may try to imitate Sazae and potentially choke on food.
