Yoshimura also helped create the Amerasia bookstore. The bookstore was one of the only places that sold books by Japanese-American authors. In the early 1970s, Evelyn joined the newspaper Gidra. Gidra wrote about the Asian-American movement. It’s often viewed as “the voice of the Asian-American movement”. She’s also an original staff member for the Little Tokyo Service Center (LTSC), which supports Japanese-Americans, especially in Los Angeles’ “Little Tokyo” district. After the LA riots in 1992, they helped Asian-Americans and other riot victims as well. The LTSC was an existing community service group that was already organized. This made it easier for them to help.
