일본 프로야구의 역사는 언제부터 시작되었는가?
In 1907, the first game was held that had a fee to watch. From 1908, several United States professional teams toured Japan and played against amateur teams made up mostly of university students, including both the Chicago White Sox and the New York Giants in 1913. Realizing that a professional league was necessary to improve, two professional teams were established in 1920. In the same year, teams held exhibition tours in Korea and Manchuria to spread baseball. This first professional league disintegrated in 1923 for financial reasons, and after repeated attempts to revive a professional league, it formally disbanded in 1929.
