Kazutomi ‘Tsuki’ Kozuki was born in Japan in 1980. He is a performer, singer and composer of electronic music. He started working in 2004 as a dancer for Baby-Q Dance Company in Japan and moved to Tokyo in 2005. Feeling a connection with the European dance scene Kazutomi auditioned for Belgian director and theatre-maker Jan Fabre. Fabre selected him as the only Japanese performer for Requiem for a Metamorphosis, which premiered in 2007. In 2008 Sidi Larbi Cherkaoui invited him to join Origine, an intimate project at Toneelhuis in co-production with De Bijloke. This project, with only four dancers and three musicians, toured all over Europe. Both projects led to Kazutomi being nominated in BalletTanz magazine in the category of Best Dancer. 

Kazutomi Kozuki then stayed in Antwerp to work for Cherkaoui as a dancer and creator on a long-term basis. During the tour of Origine, he also joined Sutra at times, working with the Chinese monks of the Shaolin Temple. He worked with Vladimir Ivanoff's Sarband music ensemble for which he created the choreography of Sinbad the Sailor, performing as Sindbad in the Music Festival at Graz in Austria. Young Japanese choreographer Kaori Ito, based in Paris, asked him to dance in her creation Noctiluque. He also assisted Cherkaoui during the creation of Dunas with María Pagés in 2009. 

In 2010, he joined Eastman and dances in Babel(words) (2010), TeZukA (2011), Puz/zle (2012), 4D (2013), 生长genesis (2013) and Shell Shock (2014). In 2015 he performed in the theatre production Pluto based on the award-winning manga series by Naoki Urasawa and Takashi Nagasaki at Bunkamura in Tokyo, under the direction of Sidi Larbi Cherkaoui, and he also got invited to perform as a guest for Royal Ballet Flanders in Fall. One year later, he performed as a hologram in Human Sanctuary for the Game Changers exhibition at MoMu in Antwerp, and joined the cast of Les Indes galantes and Alceste at Bayerische Staatsoper, and Icon and Stoic at GöteborgsOperans Danskompani. He is also part of the original cast of Satyagraha, which premiered in 2017 at Theater Basel.
