Tokyo Bay is one of the most congested areas in the world ,where about 500 vessels come and go every day. In the past, the traffic control room of each port was located around the bay, but Tokyo Bay vessel traffic control was unified to improve chronic traffic congestion and emergency vulnerability, and it was integrated into the TOKYO WAN Vessel Traffic Service Center in Yokohama. While the number of vessels in the bay is gradually decreasing, the total tonnage of the vessels is increasing year by year, and the importance of traffic control for large vessels is further increasing.
