Environmental destructions caused by military activities ("military environmental problems"), though these cause serious damages, don't have taken up as academic research subject. Because getting information on military environmental problems is difficult. To solve this difficulty we use U.S. Freedom of Information Act. In this paper I adopt "political economy on pollution" developed by Professor Shigeto Tsuru and so on as analysis method. Through analysis on released documents and examination on U.S. Department of Defense's policy on cleanup, we find three problems on influence to environment, two problems on getting information on military base pollution, one problem on cleanup. First we have to know pollution condition comprehensively through the military base investigation. Second we have to demonstrate case and responsibility on military base contamination. Third we have to require U.S. forces to cleanup at appropriate level. Through above we have to resolve military base pollution problem. When we consider as scholarship, we have to deepen theory on damage, cause, and responsibility to discuss theory on measure and cost on military base pollution.
