Asano was born in Suzuka, Mie Prefecture, in 1914. After graduating from high school, he joined army from 1932 and was sent to Manchuria for one year. In 1933, returning to Japan, he started to paint abstract works, having been influenced by Riichi Noda (1907-1987), a poet and art critic who lived next door.
Largely self-taught, he developed his own unique abstract style free from conventional values that might come from an academic training. In 1957 he started to produce works using hikkaki (scratching) method where he applied multiple paint layers, then scratched into the top surface before it dried, producing intricate designs. Rhythmic lines produce a lyrical and contemplative composition.

His work has also entered many museum collections including The National Museum of Modern Art, Tokyo, Aichi Prefectural Museum of Art, Mie Prefectural Art Museum and The Museum of Modern Art, Toyama.
