Many people look for a very special place to hold their wedding, so it's no surprise that Hawaii is a popular destination for nuptials. Most of the folks I know who were married in Hawaii did so on an isolated beach in Maui, or Kauai, or the Big Island.
I was a little surprised to see what a popular destination Honolulu (especially Waikiki) is with couples from Japan. Japanese tourism is very important to Oahu's economy and it seems that the Japanese like having their wedding photos taken on the busy streets of Honolulu or Waikiki Beach. In one hour walk on a Thursday afternoon, we saw 5 different Japanese couples having their wedding photos taken in Waikiki. I snapped a few of them as well.
I wish them all much happiness!
