The submission of the environmental assessment on Henoko in Okinawa sparked polarized reactions from the governments in Tokyo and Washington and the people of Okinawa, underscoring the gap in awareness over the contentious relocation of the Futenma air base.

Despite thunderous public outrage among Okinawa residents, Prime Minister Yoshihiko Noda had repeatedly expressed his intention to submit the report by the end of the year. And in the end, the Defense Ministry was unable to hand the report to the Okinawa Prefectural Government directly as planned and was forced to use the mail.

Pundits say Noda was adamant about submitting the report by Dec. 31 as a show of good faith to the United States. Amid the gridlock facing the Futenma plan, the U.S. Congress lost patience and recently decided to cut $150 million from the 2012 budget to move thousands of marines from Okinawa to Guam, which was a major part of the relocation package.
