Inoue Yuichi was born in 1916. He is a Japanese calligrapher who was described as "a representative artist of Japan in the late 20th century" in a letter by Robert Motherwell, a representative painter of abstract expressionism, sent to Masaomi Unagami who discovered him. Inoue Yuichi, using a large brush filled with abundant ink, wrote a character vigorously on oversized Japanese paper with surrendering himself to the full dynamic of the body. In particular, his "Ichiji Sho" where he dynamically wrote a single Chinese character on a large screen is well-known as a series of his best representative works.In his later years, he referred to himself as "Hibi Zeppitsu", and his dramatic calligraphy continued until his death.
Inoue Yuichi's works consist of powerful and towering single characters such as "mountain" and "tiger," boldly and uniquely written with his own technique. He re-created the spirit of Eastern brush and ink as a completely original expression within the context of contemporary art, receiving high reputation worldwide. Breaking the conventional concept of "calligraphy," he innovatively fused the symbol of "calligraphy" representing the spirit of the East with the inspiration from the Western avant-garde expression known as "action painting." His achievements and subsequent influence were significant. His extensive body of work, numbering in the thousands, played a significant role in the post-war Japanese contemporary art scene, often being called "Eastern Jackson Pollock". Currently, his calligraphy is considered one of the innovative movements that cannot be ignored when discussing the history of Japanese contemporary art, alongside the "Gutai Art" and "Mono-ha" movements of the 1950s.
