Tokyo Bay, Bay in Kantō region, Japan
Tokyo Bay is an inlet of the Pacific Ocean covering roughly 1,500 square kilometers (579 square miles) along the coasts of Tokyo, Kanagawa Prefecture, and Chiba Prefecture. The water extends from the open sea into protected harbors and receives flow from several river mouths.
The bay has served for centuries as a gateway to the city and witnessed pivotal events, including Admiral Perry's arrival in 1853. On September 2, 1945, the Japanese surrender was signed aboard USS Missouri while the ship lay anchored in its waters.
The waterfront promenade along the bay offers pedestrian zones with viewing points, parks, and public plazas that residents use for walking and relaxation. The name derives from the capital city, whose modern skyline reflects across the water.
The Trans-Tokyo Bay Highway links Kawasaki with Kisarazu through an undersea tunnel roughly 9.5 kilometers (5.9 miles) long and a bridge spanning about 4.4 kilometers (2.7 miles). Ferry services operate regularly between multiple piers along the shoreline.
Sarushima remains the only natural island within the bay and now functions as a marine park with remnants of fortifications from the Meiji period. Visitors reach the island by a short ferry crossing from the mainland.
