Tokyo Bay (東京湾, Tōkyō-wan) is a large bay located in the southern Kantō region of Japan. It touches the coasts of three important areas: Tokyo, Kanagawa Prefecture, and Chiba Prefecture.

The bay is connected to the huge Pacific Ocean through a narrow passage called the Uraga Channel. In the past, this bay was known as Edo Bay (江戸湾, Edo-wan). Today, the area around Tokyo Bay is home to the most people in Japan. It is also the most developed and industrial part of the country. This means many factories and businesses are located here.

What is Tokyo Bay?

Tokyo Bay is a semi-enclosed body of water. It is almost completely surrounded by land. This makes its waters calmer than the open ocean. Many rivers flow into the bay, bringing fresh water. This mix of fresh and salt water creates a special environment.

Where is Tokyo Bay Located?

Tokyo Bay is on the eastern side of Honshū, Japan's largest island. It is a very important waterway for the cities around it. These cities include the capital city of Tokyo. The bay's location makes it a key spot for trade and travel.

How Deep is Tokyo Bay?

The average depth of Tokyo Bay is about 40 meters (130 feet). However, in some parts, it can be as deep as 70 meters (230 feet). This depth allows large ships to enter and exit the bay easily.

History of Tokyo Bay

Tokyo Bay has played a big role in Japan's history. It was once called Edo Bay. This was because the city of Edo (now Tokyo) was located on its shores. The bay was important for fishing and transportation.

A Place of Change

Over time, the bay's shape has changed. Land has been added along its edges. This was done to create more space for cities and industries. These changes have made the bay smaller in some areas.

Life in and Around the Bay

Even with all the development, Tokyo Bay is home to many types of plants and animals. Fish, birds, and other creatures live in its waters and along its shores. Efforts are made to keep the bay clean. This helps protect its natural environment.

Important for People

Tokyo Bay is very important for the people of Japan. It is a major shipping route. Many goods are moved in and out of Japan through this bay. It also provides places for recreation, like parks and beaches.
