yokosuka is a fun place, but i def. dont envy the traffic you will be driving in. i used drive for the DODEA schools here, and we would drive the 51pax busses from misawa to all of the kanto plains schools. RT16 can burn in a lake of boiling feces...haha
that trip from tokorozawa to camp zama could take up to 6 hours with that garbages assed traffic...
