Are you PCSing or deploying to Japan? When I PCSd to Japan my family had to get a "no cost passport" which was funded by my orders and looked like a normal blue passport but had a stamp in the back to differentiate it from our normal civilian passport. As the military member I don't think I had a "no cost passport" and I executed official travel on orders and ID. My family and I all had normal civilian passports that we had to use to execute personal travel on. So, when I PCSd to Japan on official travel I used passport+ID and my dependents used the "no fee passport." When we went on leave to Thailand, Hong Kong, etc we travelled on our civilian passports. Confusing as all hell but such was life. At no point was I given nor did I need a red passport. I used to have a red passport back in my fleet squadron but never used it as all official travel to foreign countries was done via ID and orders. If you are PCSing to Japan the Js at Narita are well acquainted with US PCSs. There was even a sign up that directed all incoming US MIL to a special line at customs. They wanted orders and ID.
