# List of Yomiuri Giants managers

The Yomiuri Giants are a professional baseball team based in Bunkyo, Tokyo, Japan. The Giants are members of the Central League (CL) in Nippon Professional Baseball (NPB). In baseball, the head coach of a team is called the manager, or more formally, the field manager. The duties of the team manager include team strategy and leadership on and off the field. The team has employed twelve different managers since the formation of a professional baseball league in Japan. The current Giants manager is Tatsunori Hara.
In 1934, an All-Japan team was formed to play sixteen games against a Major League Baseball All-Star team in Japan. After seeing the enthusiastic fan response to these games, Yomiuri Shimbun-owner Matsutarō Shōriki decided to keep much of the Japanese team intact to form the Great Japan Tokyo Baseball Club in December of that same year. This team spent much of the next year in the United States playing various Minor League and amateur teams. During this time, the team's managers were Japanese Baseball Hall of Famer Daisuke Miyake and Yoshio Asanuma. Encouraged by the success of Shōriki's team, which had quickly changed their name to the Giants, other Japanese teams were formed and Japanese Baseball League, Japan's first professional baseball league, was established in 1936.
The Giants dominated the Japanese Baseball League. The team won nine championships in sixteen seasons under five different managers. Sadayoshi Fujimoto, the team's first manager, held the position for ten seasons and has the highest winning percentage of any Giants manager. Hideo Fujimoto was a player-manager from 1944 to mid-1946, however the 1945 season was cancelled because of World War II.
Since the NPB was formed in 1950, the Giants have had eight different managers. Starting with the NPB's inaugural season, Shigeru Mizuhara managed the team for eleven seasons, earning the team its first four Japan Series titles. Mizuhara's total winning percentage was .638, the highest of any manager in the NPB-era. Following Mizuhara, Tetsuharu Kawakami began a 14-year managerial tenure in 1960, the longest in franchise history. Under Kawakami, the team won eleven more Japan Series titles, including nine consecutive titles from 1965 to 1973. Kawakami won 1,066 games as the Giants' manager, the most in franchise history.
