The indigenous people of Hawaii called Pearl Harbor "Wai Momi", which means the water that is rich in pearls. It used to have a lot of pearl clams, so it was named "Pearl Harbor" because it was attacked by Japanese troops in the Second World War. The bombing has been famous since then and is currently the second largest tourist attraction in Hawaii. In May 1962, US President Kennedy appointed the Arizona Shipwreck to be the National Cemetery, and established a white memorial on the water and underwater Arizona.
