Rob of Rob's Japanese Cards has this to say about Kawakami:
Known as the "God of Batting", Kawakami was one of Japan's greatest stars in the 1940s and 1950s and became its greatest all-time manager. As a player, he played first base for the Yomiuri Giants both before and after World War II. He led the league in batting 5 times, in hits 6 times, in RBI 3 times, and HRs twice. He was also a three time MVP and selected for the Best Nine team 10 times. His .313 lifetime batting average ranks 5th on the all-time list. As a manager, Kawakami led the Giants from 1961 to 1974. During this 13 year period, the Giants won 11 Japan Series titles.
These cards seem to be fairly rare.

Here's a picture of Kawakami on a movie poster made by Nikkatsu Corporation in 1957.
