[Machine Translation] This book is the first study of Western-style painter Kume Tamijuro, who died at the age of 30 after encountering the Great Kanto Earthquake. Based almost exclusively in London during World War I, he interacted with poets Ezra Pound and W.B. Yeats and came into contact with avant-garde vorticism (Vorticism), but he also developed an interest in the occult, and as a result, after returning to Japan, he called himself a "mediumist" and exhibited his work in New York and Paris with a booklet of his conception translated into English. He presented his works in New York and Paris with a pamphlet of his ideas translated into English. This work clearly depicts the historical background of the Western art world from the 1910s to the 1920s, and reveals the whole picture of Tamijuro Kume, a pioneer of Japanese modernism.
