an airbase you have to visit when in Japan is Akeno. There is no fence in the approach area. When here, you can shoot all over the platforms. There is a grass runway which is used by every helo which is parked in front of you. Only the Apaches and some further away parked helos did use the intersection.
here some highlights (and the earlier requested / promised helos).
