Of the leading ukiyo-e designers, Toyokuni was the least original, but he succeeded so well in emulating the finer points of his more creative contemporaries that, in his best work, he is universally accorded a place nearly equal to theirs. He was also a noted ukiyo-e painter, print artist, and illustrator. He borrowed the character “Toyo” from the name of his teacher, Toyoharu, and named himself Toyokuni. Down to the present day, at least five separate artists have used this name, and signed their prints "Toyokuni"; one of the difficulties for a beginning collector is learning to recognize which generation artist designed the print.
Sugai lived and worked as painter, sculptor and print maker in Paris from 1952. His work is shown in major museums world-wide. He started print-making in 1952 after which it became a major part of his oeuvre. He produced some 400 prints. His style showed a major change from around 1962 when he adopted 'hard-edge' geometric imagery in contrast to he previous oriental calligraphy-influenced brush like style.
