Eiji Sawamura
After getting his degree at Rikkyo University, Kageura joined the Tigers of the nascent Japanese Baseball League (JBL) and he was a good rival for Eiji Sawamura of the Giants. Kageura won the 1936 JBL ERA title with a 0.79 mark. He did not play in the JBL from 1939 to 1942, returning to the Tigers for the 1943 season (although he did not pitch that season).
