Yumi Nakashima

She was the guitarist and main vocalist in the rock band GO!GO!7188 and is the founding member of Chirinuruwowaka.

Nakashima's interest in music started in middle school after hearing her older sister's cassette tape of the song "Shima Uta" by rock band The Boom.

The following year, in 1993, Nakashima attended The Boom's concert at the Kagoshima Citizen's Cultural Hall [ja] and was inspired to form a band once in high school.

[1] In 2005, Nakashima formed Chirinuruwowaka after finding that she preferred to work with a band as opposed to being solo.

Tanaka also brought in Anzu Suzuhara and Junpei Hayashida to contribute to the songs.
