Yanokami is a musical unit formed by Akiko Yano (????) and Rei Harakami. Yano discovered Harakami's work in 2003 and approached him about working together. Harakami had been a fan of Yano's work for a long time and was happy to collaborate with her. The two began working together in 2004 and debuted formally as Yanokami in 2007 with a self-titled album. They concentrated mainly on live performances from 2008 to 2010, playing at both small venues and large festivals.
