I believe this is a postcard I obtained when I stayed at the now-defunct Akasaka Prince Hotel in the late Showa era. The postal code is 5 digits, and the telephone number has 7 digits after the Tokyo 03 area code, a nostalgic reminder of the Showa era. I have kept it for a long time, and there are no noticeable scratches or stains. Please check the images carefully before purchasing.
