Tentenko (テンテンコ) is a Japanese singer, producer, and DJ. She was a former first-generation member of BiS from 2013 to their disbandment in 2014. Afterwards, she became a self-produced soloist, performing both as a singer, and a composer of experimental electronic music.


Early Career

In 2006, Tentenko founded the experimental unit FLORIDA with her childhood friend Takizawa Tomoe. Their music was mostly ambient soundscapes that they would record on cassette tape and sell at their local record store.

By 2012 she was singing with a band called Hakoiri Kibun (箱入り気分), but as they weren't very popular, Tentenko got a job at idol bar Dear☆Stage, hoping to draw attention and increase the band's fame.


On May 26th, Tentenko joined BiS alongside First Summer Uika and Kamiya Saki. Having been interested in the group before, she attended their audition hoping to meet the members, only to also end up joining them.

Tentenko's first single with BiS, DiE, was released on June 26th.


On February 2nd, BiS officially announced that they would disband in July.

Tentenko's only studio album as a member of BiS, WHO KiLLED IDOL?, was released on March 5th.

On July 8th, BiS' first generation disbanded at Yokohama Arena. During the show, Tentenko announced that she would return to being a freelance musician. At around the same time, she also made the decision to reform FLORIDA. Soon after graduating from BiS, Tentenko launched her own magazine, Tentenko ZINE, and began crowdfunding for her own record label and debut single.

On September 11th, Tentenko released her first solo DVD, Fuuin Sareta Tentenko no Eizo 1.

Starting with Hibiya Kouen on September 30th, Tentenko also started recording and releasing self-produced CD-R albums on a near-monthly basis. Unlike "Good bye, Good girl" and later studio releases, these albums typically consisted of (usually instrumental) tracks in the dark ambient, dub and noise genres.

On October 11th, another internationally-released Tentenko album, Deep & Moistures: The Best of Private Tracks, was released. It was a compilation album of tracks from her long-running Deep & Moistures series of CD-Rs.

After almost five years, Tentenko finally ended her series of monthly CD-R releases with her fiftieth consecutive release, Deep & Moistures 22 ~ Silver Lining, on January 13th.
