2005: Beginning

Chirinuruwowaka were formed in 2005 by Yumi Nakashima. Through the recording of her solo album, Ten no Mikaku, released the previous year, she realized that she wanted her next solo album to be made with a band.^[2]

She first invited bassist Iwai, whom she was always interested in although knowing him only by a recorded performance, to GO!GO!7188’s tour, and she met him for the first time. She formally asked him to join the band. Then Nakashima chose drummer Abe who participated in the recording of her solo album after some sessions with several drummers. Finally Nakashima auditioned guitarists, and Miyashita who was 20 years old passed it.

On September 28, 2005, they released the first album "Iroha" from Toshiba EMI.

On May 15, 2006, they released the first single "Shingetsu" from BM tunes.

2007-2009: Hiatus

Miyashita left the band during hiatus.

2010-Present: Restart

In September 2010, Chirinuruwowaka resumed activity with new guitarist Natsuki Sakamoto, who joined in January 2010.^[3]

In early 2016 it was announced that guitarist Natsuki Sakamoto had left the band.^[4] The band decided to carry on as a three piece. In 2019, Kosaku Abe also left the band, leaving Nakashima and Iwai as the two remaining original members.^[5]
