Does Japan really belong to "western countries"?  

Few days ago,I have seen a section of article"Eiffel Tower,New York's Empire State Building, Tokyo TV ower are western three famous buildings" it amazes me,here the Tokyo TV Tower isn't in Japan,after laughing at the editor's ignorance,then I search the so-called "western theory" on the net.
People often say the three standards of eastern countries:geography position,culture background and political system.Affecting by the over of cold war and global influence,the confine for eastern countries are gradually blurry currently.
Traditionally in geography and culture Japan belongs to east,but in its political systerm Japan still implement western capitalism democracy,its economy system is similar as western countries' model.Japan has always been trying to "go out Asia and go into Europe",work hard to close to western,now it has been the members of western eight countries.
Does Japan belong to west or east?Let's analysis together........
