Edward Papazian, an American, visits the U.S. Navy bases at Yokosuka and Atsugi, both in Kanagawa Prefecture, once every two or three months, escorted by a former navy friend.

His friend has a U.S. military pass that gains him entry to U.S. bases anywhere in the world. Such passes are given to those who work or have worked for the U.S. military. Papazian, 49, like many people, needs someone like his friend with a pass to get him onto a base.

As well as being accompanied by someone with a pass, those who want to enter also need to show their passport and additional identification at the gate.
