When I wear my Detroit Tigers baseball hat I get treated differently. I'm not an afficianado of Japanese culture as a resident. I'm a tourist when wearing the hat. It sucks. I argued with a waitress at a restaurant I've visited many times about the fact that they have an English menu. It took another server to recognize me me get the conversation past the disconnect. Then I visited a pub oriented to foreigners. When I ordered a traditional drink I was grilled to make sure I knew what I was ordering. So, Westerners coming to Japan: don't wear baseball hats and hide your tattoos.
