There are times in Japan, luckily not too often, that I feel like a criminal just for being a foreigner.
I forgot to tell you that when I came back from my trip to Japan, I was asked by police to produce my alien card. It was a first for me. Of course I had to show my "Certificate of Alien Registration" in immigration, that was expected. But later, as Wayne and I were waiting for our train, outside of the the airport, we and other foreigners waiting were asked to produce our cards again, this time to different officials. The police officer then interviewed me for about ten minutes as he took down all my details and also asked to see my passport and visa.
