Left great achievements as an international historian
People say, "Everyone quotes the works of Dr. Asakawa when writing papers on Japan's feudalism." This attests to Dr. Asakawa's international renown as a scholar.
Dr. Asakawa won immortality by publishing "The Documents of Iriki" in 1929. The document contributed substantially to the comparative study of legislative annals. He also left world-famous works including (a) the Yale University Graduate School degree thesis he wrote in English on the "The Early Institutional Life in Japan ; A Study in the Reform of 645 A.D." (published in 1903), and (b) the collection of his posthumous works on "LAND AND SOCIETY IN MEDIEVAL JAPAN" (published in 1959).
Aggressively engaged in peace activities as an internationally known scholar
Dr. Asakawa, as a Japanese living in the United States over a long period, objectively observed the conflicts in which Japan participated, from the Russo-Japan War to World War II. He left works on "The Russo-Japanese Conflict ; Its Causes and Issues" (written in English and published in 1908), as well as on omens of disaster for Japan (written in Japanese and published in 1909). He also exchanged a huge volume of letters with Japanese as well as with American and European intellectuals, and in 1941 drafted for President Roosevelt a letter addressed to Emperor Showa. Through his writing activities, he devoted himself to the improvement of U.S.-Japanese relations at a governmental level as an internationally respected personality.
