Back in the 1950s Gardena was a pretty bucolic place, and the largest minority was Japanese.
Yup, I grew up there. I went to grammar school and junior high with many Japanese. The nicest, most polite, un-assuming people I've ever known. They had a lot of moral integrity and a appreciation of what America stands for second to none. A very close friend was Japanese or nissey or whatever the word was for second generation Japanese-Americans.
The only thing I know about Gardena is that they used to have dirt track races there at Ascot Speedway.
