Kyoko Endo was born in Kanagawa, Japan. She started playing the piano at the age of six, but during her school years she wanted to be an actress rather than a musician. Her life changed when she was 17 years old. Her music teacher at school suggested that she become a singer. So she studied voice and eurhythmics at Kunitachi College of Music. She also graduated from Haikyo Theater School and built her career as an actress. Trained as a singer in Japan and Berlin, she has performed in operas, classical concerts, musicals and avant-garde concerts in Japan and Germany. She is also skilled in improvised music. She is a member of the The Japanese Association for the Study of Musical IMprovisation (JASMIM). She has performed in Japan, Berlin, and Vienna in live improvised collaborations as an opera singer with dancers, and other instrumentalists, all to great acclaim. She has won second prize at the AMIGDALA International Music Competition – memorial “G. Raciti”  in Italy, second prize at the The North International Music Competition in Sweden, and a prize at the International Moscow Music Competition in Russia. She has studied voice with Masaru Arihara and Heike Lerer.
