Kayoko was born in Japan into a family of artists. Her mother is a ballerina and ballet teacher who graduated from the Royal Academy Dancing of London (R.A.D.) and currently runs her own school in Japan. Her brother is a pianist in Vienna (Austria) and also accompanies classes at the Ballet School of the Vienna State Opera (Balletakademie der Wiener Staatsoper). His father, a great lover of jazz and classical music, was awarded the first prize of critic of the music magazine Jazz "Swing Journal", very famous in Japan at the time.

These Parisian years allowed Kayoko to make a name for herself, during professional training at the Harmonic studio, at Choréia or at the Kim Kan dance school. She took the opportunity to meet important personalities from the French dance scene.

At the same time, Kayoko is training for the state diploma of dance teacher, in the pedagogical section with Cathy Bisson, (teacher at the Conservatoire National Supérieur de Musique et de Danse de Paris). She obtained her diploma in 2007 and teaches in several international schools, conservatories as well as in a public school for professional training, where she passes on her know-how to young people who wish to become professional dancers.
