Handa was born in 1974 in Japan. He started to take piano lessons and to study music at the age of 6. He was 9 years old when he wrote his own music. He longed to go to school of music to study specialised music, but his household economy didn't allow that. He graduated in law and medicine. Now he is a "Sunday composer" or "midnight composer" working as a surgeon. He belongs to several choral groups and often composes or arranges music for them. He leads male chorus group "Societas Artifectis Yechigoya Sohonten" as Nugatore Primus; in English, Chief Visionary Officer. Sometimes he writes music (songs and background music) for theatrical groups.
