Ikimono-gakari is a Japanese pop rock band from Kanagawa Prefecture, Japan. The group started in February 1999 with Hotaka Yamashita and Yoshiki Mizuno, and was joined by vocalist Kiyoe Yoshioka in November of the same year. The group's name is a reference to ikimono-gakari, a group of children who are responsible for looking after plants and animals in Japanese elementary schools.
In 2006, the group released its first single on Sony Music Entertainment Japan's Epic Records label. Several of their albums have reached number one on the Oricon weekly rankings, and their songs have been featured on various media: from TV commercials, anime shows such as Naruto Shippuuden, Japanese TV Dramas such as Women Won't Allow This, live action movies such as Time Traveler: The Girl Who Leapt Through Time, the 2012 Olympic broadcast theme song for NHK, and the set piece for a national junior high music competition.
Their official fan club is named Ikimonogakari Fan Class 1-2
Mizuno has the most number of composed songs among them, while Yamashita ranks second. Yoshioka has contributed lyrics to a few songs, but Namida ga Kieru Nara is the only song on which the three of them have collaborated.
