For the 1940 and 1941 seasons, the team changed its name to Kurowashi (Black Eagles in Japanese; in October 1940, responding to rising hostility toward the West due to World War II, the league outlawed the use of English words in Japanese baseball).
[citation needed] Tadashi Kameda pitched two no-hitters for Kurowashi, on March 18, 1940, against the Lion Baseball Club, and on April 14, 1941, against the Osaka Tigers.
[2] Kenkichi Saeki, president of Yamato Ironworks, purchased the team in 1942.
As a result, the team changed its name to the Yamato Baseball Club.
[citation needed] During its nine seasons of existence (including split fall and spring campaigns in 1937–1938), the franchise only had two winning campaigns and never finished higher than third in the JBL standings.
