Onigiri

Onigiri (Also known as Riceballs in the US) is a Japanese Entertainment, Merchandising and Media Franchise based on the 1951-2001 Manga series created by Waku Yaniko and published by Takara (later Onigiri Productions). The first anime series based on Onigirl, Nao and Toro (Nao to Toro) aired on Tokyo Channel 12 from 1977-1989 alongside 2 American show The Nao and Toro Show and Riceballs. The Onigiri and Riceballs names are rarely seen in any promotional markets due to Waku hating the names, considering them "the worst name for a franchise".

Trivia
