	The Unions were owned by Ryutaro Takahashi, the former president of Dai-Nippon Beer and owner of the Eagles Baseball Club/Kurowashi Black Eagles from 1939 to 1941. Takahashi had originally wanted to name the Unions the "Takahashi Eagles" after himself and a beer that had been produced by Dai-Nippon. However, the teams's name ended up being chosen by a public vote.
