Yesterday afternoon we hired a car and went to one of the outlet malls outside Tokyo.  We really liked the Mitsui Outlet Park, but were more excited by the drive.  To get there we drove through the Tokyo Bay Aqua Line. It is a 15 kilometer long bridge-tunnel across Tokyo Bay that connects Kawasaki to Kisarazu. 9.6 km are under the bay, making it the fourth longest underwater tunnel in the world.

It is not cheap to use. As we used it on the weekend we were charged 800 円 (5.43 GBP) each way. During the week that would be closer to 3,000 円 (20 GBP) each way. We found it fascinating, and the part that is a bridge is beautiful as you just don’t expect to come out of tunnel on to a bridge that is out in the sea.
