Diamonds in the Rough: Japanese Americans in Baseball presents the hidden history of Japanese American baseball, from the turn-of-the-century Issei teams to the present-day legacies. This exhibition adds an important voice to the annals of baseball history.

With artifacts, photographs, video, and a diorama of Zenimura Field at Gila River concentration camp, it demonstrates how the history of Japanese American baseball reflects the cycles of discrimination and acceptance that have defined the entire Japanese American experience.

Diamonds in the Rough is organized by the National Japanese American Historical Society in collaboration with the Nisei Baseball Research Project. The exhibition premiered a the California State Capitol Museum and has traveled to The Presidio of San Francisco; the National Baseball Hall of Fame in Cooperstown, New York; and the Baseball Hall of Fame and Museum in Tokyo, Japan. The Japanese American National Museum is the only Los Angeles venue of this historic exhibition.
