Sadayoshi Fujimoto

 was a Japanese baseball manager, most notably as the first manager of the Tokyo Kyojin, which was later renamed to the Yomiuri Giants. With the Kyojin, he won the Japanese Baseball League pennant seven times. He was also the manager of the 
Pacific Baseball Club (renamed to the Taiyo Robins during his tenure), the Hankyu Braves, and the Hanshin Tigers.
Fujimoto is third all-time for Japanese baseball managers in terms of career wins, with 1,655. He was inducted to the Japanese Baseball Hall of Fame in 1974.
Early life.
Fujimoto was born on December 20, 1904, in Matsuyama. He attended , where he played baseball as a pitcher and third baseman. He participated in the Japanese High School Baseball Championship each of the four years he attended. He then attended Waseda University, also playing baseball. He graduated from Waseda in 1929.
Managerial career.
Tokyo Kyojin.
In 1936, Fujimoto was appointed manager of the Tokyo Kyojin, also known as the Giants, for its inaugural year. The Japanese Baseball League was initially played in series of half-seasons, the first being the fall season of 1936. Under Fujimoto, the Kyojin finished the season with a record of 18–9, finishing second in the league, behind the Osaka Tigers. The Kyojin and the Tigers played a best-of-three playoff series to determine the champion of the half-season. The Kyojin won, 2–1. The Kyojin would win the next half-season as well, with a record of 41–13–2, beating the Tigers by a half-game. The Kyojin wouldn't win the next two half-seasons, but won the 1938 fall season in convincing fashion, beating the Tigers by 3.5 games.
The league did away with the half-season format in 1939 and installed a full-season format, which would be used from then on. The Kyojin continued winning seasons under Fujimoto, winning the 1939 season with a 66–26–4 record, the 1940 season with a 76–28 record, the 1941 season with a 62–22–2 record, and the 1942 season with a 73–27–5 record. The 1940 and 1942 seasons are considered especially dominant in regards to the history of Japanese baseball. The team won by 10.5 and 12.5 games, respectively.
Fujimoto resigned as manager in 1943, to serve in World War II. Fujimoto was unable to regain his position following the war.
During his tenure, Fujimoto became infamous for his harsh practice routines, which teams adopted following the success of the Kyojin. The routines were dubbed "vomit practice", due to players regularly vomiting due to exhaustion. Osamu Mihara was quoted in his memoir:
Several members of the Japanese Baseball Hall of Fame served under Fujimoto while he managed the Kyojin. Shigeru Chiba, Shosei Go, Tetsuharu Kawakami, Shigeru Mizuhara, Haruyasu Nakajima, Eiji Sawamura, Victor Starffin, and Kazuhiro Yamauchi all played for Fujimoto and went on to be inducted to the Hall of Fame.
Pacific Baseball Club/Taiyo Robins.
Fujimoto got another chance to manage a baseball team in 1946. The offer was from the Pacific Baseball Club, formerly named the Asahi Baseball Club. The team had poor records since its inception, with only one winning season in its ten-year history. Under Fujimoto, the team finished with a 42–60–3 record for the 1946 season. The team renamed itself as the Taiyo Robins for the 1947 season, but the newly named team failed to achieve a winning season this year either, finishing 50–64–5.
Hall of Famer Juzo Sanada spent time under Fujimoto during his tenure with the club.
Kinsei/Daiei Stars.
Fujimoto took the helm of the Kinsei Stars in 1948. The Stars were a fairly new team that was in its third season. Under Fujimoto, the team finished the season with a record of 60–73–7. 1949 saw the team change its name to the Daiei Stars, with the fortunes changing as well. The team finished 67–65–2. This was the first time a Fujimoto-managed team finished with a winning record since he left the Kyojin.
Nippon Professional Baseball replaced the Japanese Baseball League in 1950, and the Daiei Stars were one of the founding members of its Pacific League. The team continued its winning ways, finishing 62–54–4. The team then entered a two-year losing skid, finishing 41–52–8 in 1951 and 55–65–1 in 1952. 1953 saw a 63–53–4 record, but the last three Stars seasons under Fujimoto proved to be abysmal, finishing 43–92–5 in 1954, 53–87–1 in 1955, and 57–94–3 in 1956.
Hankyu Braves.
Fujimoto took the helm of the Hankyu Braves for the 1957 season. The team finished with a winning record for the first two seasons under Fujimoto, with an 71–55–6 record in 1957, and a 73–51–6 record in 1958. 1959 was a poor season for the team, finishing 48–84–2.
Hanshin Tigers.
Following a two-year hiatus from managing, Fujimoto acted as the interim manager for the Hanshin Tigers and was later appointed as the manager in 1961. The team finished 60–67–3 for the season.
1962 saw great success for the Tigers. They won the Central League with a record of 75–55–3 and faced the Toei Flyers in the Japan Series. After winning the first two games of the series and tying the third, the Tigers dropped the next four and the Flyers, led by former player Shigeru Mizuhara, won the series. 1963 was an off year for the Tigers, finishing 69–70–1.
The Tigers once again reached the Japan Series in 1964, after going 80–56–4 in the regular season and capturing the Central League pennant. The Tigers played the Nankai Hawks in a competitive series, with it coming down to a game 7, which the Tigers lost 3–0.
The Tigers, under Fujimoto, failed to reach the Japan Series again. The team went 71–66–3 in 1965. Fujimoto was appointed as Hanshin's general manager in 1966 and led the team to a 64–66–5 record. In 1967, the team went 70–60–6. Fujimoto's final year was in 1968. He resigned on October 23, with the team finishing the season with a 72–58–3 record.
Later life and death.
Fujimoto was inducted into the Japanese Baseball Hall of Fame in 1974. He died on February 18, 1981, at the age of 76. His total managerial wins are the third-most of anybody who has managed Japanese baseball professionally.
