Inoue, who is one of Japan's most prolific writers today, started relatively late as a novelist. He was forty-two when he published in 1949 his first works, the two novelettes ''Ryoju'' and ''The Bullfight'', which the following year won for him the top literary prize in Japan, the Akutagawa Prize. His longer ''The Roof Tile of Tempyo'' deals both with art and ancient China; ''Lou-Lan'' and ''The Flood'' are short historical novels of China. Whether he is writing full novels, novelettes, or short-stories, however, Inoue's penchant for detailed, exhaustive research and historical accuracy give his stories a flavor of authenticity. Even the characters in his stories can often be traced back to historical individuals. In the spring of 1964, Inoue went to the United States to start his research on what he personally believes will be his magnum opus, a multi-volume treatment of first, second, and third generation Japanese abroad, particularly in the United States.
