I was in line waiting to enter the Nippon Budokan to view a title boxing match. While I was in the line I decided to take out my 6.0 mega pixel digital sony camera that was locked on to my belt and take a picture of the front of the building to keep as a souvener. I took the picture. I then took a quick look at the picture in my camera. A few seconds later I took a second look because I had seen something else on the top right coner of the picture. Suddenly a strange feeling just jolted up my body. Like when the hairs of your back just shoot right up. The feeling was very unpleasent . My body told me to look up so then I did. That was when I saw the silver disk like shape. The hovering disk was emitting some sort of eerie black shade underneath it I don't know what it was. My eyes just went wide open, I began to sweat . The flying object was just hovering in mid air at a great distance from the floor for a couple of seconds. I quickly turned to tap the gentleman that was next to me to look. When I looked back, the flying disk was gone. No sign whatsoever of it. I later started thinking that maybe it was a result of the years in boxing that made me see things. But now I now that it was no Imagination because I have a picture of it.
