Performer and singer Kazutomi ‘Tsuki’ Kozuki was born in Japan, where he started working as a dancer in 2004 for Baby-Q Dance Company. Feeling a connection with the European dance scene, Kazutomi auditioned for Belgian director and theatre-maker Jan Fabre, and danced in his Requiem for a Metamorphosis (2007). In 2008 Sidi Larbi Cherkaoui invited him to join Origine, an intimate project at Toneelhuis in co-production with De Bijloke. Both projects led to Kazutomi being nominated in Tanz magazine in the category of Best Dancer. 

Kazutomi then stayed in Antwerp to work with Cherkaoui at his company Eastman as a dancer and creator on a long-term basis. He 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. He danced in Cherkaoui’s opera directions of Les Indes galantes (2016) and Alceste (2019) at Bayerische Staatsoper, Satyagraha (2017) at Theater Basel, and Idomeneo (2024) at the Grand Théâtre de Genève. He was a guest dancer at Opera Ballet Vlaanderen (Fall, 2015), GöteborgsOperans Danskompani (Icon, 2016, and Stoic, 2018), and Ballet du Grand Théâtre de Genève (Ukiyo-e, 2022). He appears in the Dom Pérignon x Lady Gaga: The labor of creation commercial (2023) and in fashion presentations by designers Jan-Jan Van Essche (SUNU, CYCLE, RITE) and Yuima Nakazato. Recently, Kazutomi tours with Nomad (2019), Vlaemsch (chez moi) (2022) and performs one of the three solos in 3S (2020).

His work for other artists include Sinbad the Sailor with Vladimir Ivanoff's Sarband music ensemble, Noctiluque with Japanese choreographer Kaori Ito, UMBRA with contemporary Flamenco artist Fabian Thomé, and the video clip No Light, No Light by Florence + The Machine with choreographer Damien Jalet. Kazutomi also modeled for The Boatman by Belgian visual artist Hans Op de Beeck.
