Modern Japan isn't merely a country where East meets West. The Land of the Rising Sun's story is more a case where East thought West was chou kawaii but after running through a couple different Western suitors (Portugal and Holland), East gave up on all foreigners and went totally asexual for a couple hundred years before that Chandler guy made them start airing Friends episodes in English...
