Born in Miyazaki Prefecture in 1911. In 1936, he created a unique photogram that fixes his own image on photographic paper, calling it “photo-drawings,” and made his debut in the art world with the publication of a collection of his works entitled “Reason of Sleep”. In 1951, he formed the Democratic Artists Association, which rejected the authoritarianism of the art world, and attracted many young artists who admired him, such as Ay-O. While Ei-Q worked on oil paintings and photo-drawings, he was also a vigorous self-taught printmaker, leaving behind more than 300 copper prints and 150 lithographs.

Ei-Q used a variety of techniques and materials to develop his work from realism to cubism, surrealism, and abstraction, but after 1957, with the dissolution of the Democratic Artists Association, he was freed from the complications of group activities and daily life and focused on producing abstract paintings in oil. The abstract paintings initially consisted of circles and squares, which gradually became globular shapes, which then broke and exploded, and finally became moving dots. Then the dots became smaller and smaller until they covered the entire canvas. In light of this transition, Forest is a work that can be described as a localized version of Ei-Q’s oil paintings, and it shows Ei-Q’s unique and expansive spiritual world that resembles a universe.
