Nono-chan (ののちゃん) is a yonkoma manga series begun in 1991 by Hisaichi Ishii originally serialized as My Neighbors the Yamadas (となりのやまだ君 Tonari no Yamada-kun) in the Asahi Shimbun in Japan. When the series first began, it was generally focused on all of the members of the Yamada family. As the series progressed, the daughter (Nonoko, or "Nono-chan") became the most popular character among readers and more of the strips focused on her and her point of view. In 1997, the series title was changed to reflect this change of focus. The Asahi Shimbun continues to feature this manga series as of October 2007.
