AT is right, start by emailing the ramp and let them know what you are doing. If you are on an RFO trip they will set up the ride and cover it, at least they used too. If its a full crew, talk to the other guy and set up a time that will work for both of you and they might still set it up and cover it. The main thing in Japan is to email the ramp and see what they can do for you.
