Why are there so many Japanese tourists in Hawaii?
But if you go to the beaches on the north shore or Kailua or outside of Honolulu in general, you will see surprisingly few Japanese tourists compared to Waikiki. That's because they mostly stay with Japanese tours that take them to specific tourist sites, or else they stay in Waikiki for shopping and dining. (The outer islands also have relatively few Japanese tourists.)
There are also local residents in Hawaii who are of Japanese ancestry. Their parents, grandparents, and great grandparents came to Hawaii to work in agriculture or business. Honolulu has a much higher percentage of locals of Japanese or Chinese ancestry than the rest of the Oahu does.
