Baseball In Japan Tank Tops

On August 31, midway through the 1937 fall season, Dai Tokyo changed its name to the Lion Baseball Club when it was acquired by Komajiro Tamura, with sponsorship by Lion Toothpaste. Late in the 1940 season, the Japan Baseball League outlawed English nicknames (due to rising tensions with the West). Owner Tamura refused to change the team's name, insisting that "Lion" is Japanese (In actuality, he wanted to honor the team's sponsorship contract with the Lion Corporation.)

The team began as the Taiyo Fishing Company, an amateur team currently affiliated with the Maruha Corporation. The team name was changed to the Taiyō Whales (大洋ホエールズ, Taiyō Hoeeruzu) shortly after the start of the 1950 season. The Whales received several veteran players from the Yomiuri Giants to compensate for their lack of players, but ended up in the bottom half of the standings each year. In 1951, there was talk of merging with the Hiroshima Carp, which had experienced serious financial problems but the merging never occurred due to massive protests from Hiroshima citizens.

The Osaka Kintetsu Buffaloes (大阪近鉄バファローズ, Ōsaka Kintetsu Bafarōzu) were a Nippon Professional Baseball (NPB) team based in Osaka, Japan, which was in the Pacific League. In 2005 the team was merged with the Orix BlueWave to become the team now known as the Orix Buffaloes. The team played in Fujiidera Stadium, and later in Osaka Dome. Although the team won four Pacific League championships, they lost all four Japan Series in which they played. The team's batting lineup was known as Itemae Dasen (いてまえ打線).

The Shochiku Robins were a Japanese baseball team that played in Nippon Professional Baseball (NPB). The franchise originated in the Japanese Baseball League (NPB's predecessor) and existed from 1936–1953, when it merged with the Taiyo Whales. Originally based in Tokyo, the club moved to Osaka in 1941.

The Takahashi Unions (高橋ユニオンズ, Takahashi Yunionzu) were a Japanese team in Nippon Professional Baseball. A Pacific League expansion team in 1954, they were brought into the league to increase the number of teams to eight. The team was stocked with players from the other Pacific League teams, including aging pitcher Victor Starffin. In their three years of existence the team finished in the second division every season. The Unions played their games at Kawasaki Stadium in Kawasaki, Kanagawa.

The Yamato Baseball Club was a Japanese baseball team in the Japanese Baseball League (JBL). Based in Tokyo, the franchise was founded as the Korakuen Eagles before the 1937 season and was dissolved before the 1944 season.

The Daiei Stars (大映スターズ, Daiei Sutāzu) were a Japanese professional baseball team that was founded in 1946, and played in various incarnations until 1957, when it merged with another team. Overall, the franchise only had three winning seasons, never rising higher than third place. The team was in the second division, or B-class, for seven seasons, including its last four years of existence. The Stars played in Korakuen Stadium in Bunkyo, Tokyo.

The Marines franchise began in 1950 as the Mainichi Orions, an inaugural member of the Pacific League. The Orions were named after the constellation of the same name. The Marines won the inaugural Japan Series in 1950. In 1958, the team was merged with the Daiei Unions and renamed the Daimai Orions. In 1964 they became the Tokyo Orions, and the Lotte Orions in 1969. The franchise was slow to replicate its initial success: the Orions made the Japan Series in 1960 and 1970, only to lose both years.

The Nishi Nippon Pirates were a former Nippon Professional Baseball team and a founding member of the Central League in 1950. The team was owned by the Nishinippon Shimbun and played their home games in Heiwadai Stadium in Fukuoka. After only one season in which they fell victim to the first perfect game in professional Japanese baseball history, had financial and managerial problems, and finished in sixth place, the Pirates merged with the other Fukuoka-based Nishitetsu Clippers to form the Nishitetsu Lions in the Pacific League.
