To promote travel to “Sen-Man”, as Korea and Manchuria were collectively known, the South Manchuria Railway Company, the Japan Tourist Bureau, and the Imperial Government Railways of Japan published scores of guidebooks and pamphlets aimed at orienting prospective travelers to the sights that could and ought to be seen on a journey to the continent.​
