The U. S. -Japan Security Treaty as well as The Treaty of Peace with Japan were concluded in 1951 in San Francisco. It is wrong to think that The U. S. -Japan security system began with. the conclusion of that treaty, because we can not identify the security system with the security treaty.
The security system between the U. S. and Japan came into existence with the unconditional surrender of Japan and the occupation of Japan by the U. S. in 1945. We shall think of the U. S. -Japan security system as one started by the “substantial” coupling on the political and military level between both countries.
In this essay there are three parts. First, we will examine the historical factors, particularly the Emperor system and the cold war, giving rise to the security system. Second, we will consider the nature of the treaty as a smaller part of the security system. Especially we will study the “one-sided burden” of the U. S. to Japan and the mechanism of Japanese compensation in the treaty. Third, we will forcus on American expectations of a “strong Japan” and American fear of Japanese neutralization under the security system.
Following the collapse of the cold war, it is more necessary to examine closely the structure of the security system between the U. S. and Japan in the context of the cold war.
