A Fuji TV newscaster gets a special look at one of the gigantic storm drainage tunnels deep beneath Tokyo. The tunnel shown in the video is about 40 meters (130 feet) underground and about 12.5 meters (41 feet) wide. While looking through the tunnel, the reporter and his guide are able to see marks left over from heavy rains that took place earlier this year, as well as a few marine animals that got washed in with the rainwater.
