Kitazawa Yasuji (北澤 保次; 20 July 1876 to 25 August 1955), known by his pen name Kitazawa Rakuten (北澤 楽天), was a Japanese manga and nihonga artist, who was the first professional cartoonist in Japan, and the first to use the term "manga" in its modern sense. He drew editorial cartoons and comic strips during the years from the late Meiji to the early Shōwa era. He is considered by many historians to be the founding father of modern manga, and his work was an inspiration to many younger manga artists and animators.
