Japanese planners of the Pearl Harbor attack had determined that some means were required for rescuing fliers whose aircraft were damaged too badly to return to the carriers. The island of [[Niihau]], only thirty minutes by air from Pearl Harbor, was designated as the rescue point.{{citation needed|date=May 2019}}

During the second wave, a Zero fighter flown by Petty Officer Shigenori Nishikaichi of ''Hiryu'' was damaged in the attack on Wheeler, so he flew to the rescue point. The aircraft was further damaged on his crash landing. Nishikaichi was helped from the wreckage by one of the Native Hawaiians, who, aware of the tension between the United States and Japan, took the pilot's pistol, maps, codes and other documents. The island's residents had no telephones or radios and were completely unaware of the attack on Pearl Harbor. Nishikaichi enlisted the support of three Japanese-American residents in an attempt to recover the documents. During the ensuing struggles, Nishikaichi was killed, and a Hawaiian civilian was wounded; one collaborator committed suicide, and his wife and the third collaborator were sent to prison.{{citation needed|date=May 2019}}

The ease with which the local ethnic Japanese residents had apparently gone to Nishikaichi's assistance was a source of concern for many and tended to support those who believed that local Japanese could not be trusted.<ref>{{Harvnb|Fuchida|2011|pp=293–294}}</ref>
