The
Japanese Baseball League (JBL) began operations in 1936. In 1937, Tamura acquired
Dai Tokyo, one of the founding members of the JBL, from the Tokyo daily newspaper
Kokumin Shimbun. On August 31, 1937, midway through the fall baseball season, Tamura gained sponsorship from
Lion Toothpaste, and changed the team name to the
Lion Baseball Club. Late in the 1940 season, due to rising tensions with the West, the JBL outlawed the use of English team names. Tamura, however, refused to change the team's name, insisting that "Lion" was a Japanese word. (In actuality, he wanted to honor the team's sponsorship contract with the Lion Corporation.) The team completed the season as Lion, finishing in last place, 50 games behind
Tokyo Kyojin. (Up to that point, the team had never had a winning season and had never finished higher than sixth place.) In 1941 the team moved from Tokyo to
Osaka and acquired new sponsorship from
Asahi Shimbun; from 1941 to 1944 it was called the
Asahi Baseball Club, and in 1943 had its first winning season, finishing at 41-36-7, in third place. Due to
World War II, no baseball season took place in 1945. After the resumption of the JBL in 1946, the team changed its name to the
Pacific Baseball Club (popularly known as
Taihei — "Peace"). == Founding of Gold Star; conflict ==
