Seeing some big military helicopters (like this Chinook) flying low over Tokyo is not rare at all. Most of the times they head towards the Ministry of Defense in Ichigaya, land, and take off shortly after.

Lucky enough to have spent the last 6 years of my life in Tokyo, I spend a lot of time wandering through this always amazing city, a camera and a couple of lenses in my bag, mostly Nikon... for the time being.
