K-On! is a popular Japanese anime series by Kyoto Animation. Based on a manga by Kakifly, it tells the story of a light music club in an all girls high school. The anime aired in Japan between April and June 2009.
[Update] Teaser deleted from YouTube. I’m sharing the opening song instead, Cagayake GIRLS…
The title K-On comes from Japanese word keiongaku (軽音楽). It literally means light music, which can also mean pop music in Japanese context.
The plot starts with four girls of different backgrounds joining the keiongaku club in Sakuragaoka High School to save it from disbandment. The rest is about bonding, making songs and having fun etc.
The anime director is Naoko Yamada. The voice actresses are Aki Toyosaki, Yoko Hikasa, Satomi Sato, Minako Kotobuki, Ayana Taketatsu, Asami Sanada, Madoka Yonezawa and Chika Fujito.
The TV series only has 13 episodes. Kyoto Animation probably didn’t expect the show to be that popular; they usually produce anime series with over 20 episodes instead.
To make up for it, a second season is already in progress and will air later this year.
