Sorry, I Don't Speak Japanese

Took my family to the Grand Canyon one summer a couple of years back.  There were lots of tourists, speaking lots of different languages.   The Germans speaking German next to stopped and spotted some prey nearby to flex their language skills.   One of the Germans goes over to a Japanese-looking guy and starts speaking Japanese.   As far as I could tell the German was pretty fluent and clearly pleased with himself.   The Japanese guy looked bewildered.   There was a pause, then the Japanese guy said, "I'm sorry.  I don't understand a word you said.  I don't speak Japanese.   I'm from Hawai'i."
