 Also, as long Okinawa is part of Japan, the United States military bases will not leave, because it is Japan's intention to use Okinawa as an island military base, seen from the Emperor Hirohito's "Imperial Message" (1947) and US-Japan Security Treaty valid from 1952.Even further, it is claimed that Okinawa Prefecture's status violates of Japanese constitution - a law applicable to one single entity can not be enacted by National Diet without the consent of the majority of the population in the entity (ignored during the implementation of financial plan from 1972, as well in 1996 legal change of law about the stationing of military bases).The constitution's Article 9 (respect for the sovereignty of the people) is violated by the stationing of American military troops, as well as the lack of protection for civilians' human rights.
