Freenote is a Japanese Rock band that consisted of three (formerly four, with the member Shusako sato leaving) members: Chikako Hata (Vocals, Piano/Keyboard, Guitar), Masaya Sakamoto (Guitar), and Shingo Ōta(Drums). Formed in Kansai University in 2002, the group's first mini album was published on an indy label on December 3, 2003.

The band first gained nationwide exposure when their first single, Kirai Tune (キライチューン), was used as the ending theme for the popular Japanese anime series Bobobo-bo Bo-bobo. Subsequently, they received worldwide exposure (albeit to a much lesser extent) when the series became syndicated for worldwide distribution.

Since then, the group has released a number of singles and two full-length albums, but currently remain critically acclaimed, yet without commercial success on the Japanese pop charts.

In August 25, 2013, freenote disbanded with a live performance at Shimokitazawa CLUB Que. The lead vocalist Chikako Hata became a vocal coach, and you can find her website here.

the main bassist, shusako left the group on September 30, 2015 and joined KELUN, coincidentally the band who did one of Bleach (an anime's) openings
