Fair, then Partly Piggy (はれときどきぶた, Hare Tokidoki Buta) is a picture book series written by Shiro Yadama.

[2] The book is about a boy named Noriyasu Hatakeyama who starts writing "tomorrow's" journal entries when he finds out the days start happening just the way he writes them.

[3] The English dub of Tokyo Pig was produced by Miramax Television and Buena Vista Sound Services and had all the original Japanese music completely replaced with a new musical score and all the original Japanese sound effects completely replaced with new American-made sound effects.

It was broadcast from September 2002 to March 2003 in the United States on ABC Family, and eventually on Cartoon Network Korea in June 2013.

Miramax Home Entertainment released Tokyo Pig only on one DVD with no VHS equivalent.
