geography Maturity 7-9 Next article →

Tokyo Bay is a huge body of water in Japan. It sits on the southern coast of the island of Honshu. The bay is in the Kantō region. It touches the coasts of Tokyo, Kanagawa, and Chiba. Two large pieces of land reach into the water. These are the Bōsō Peninsula and the Miura Peninsula.

Many rivers flow into the bay to provide water. The Tama and Sumida rivers flow into the city of Tokyo. The Edo River flows between Tokyo and Chiba. In Chiba, the Obitsu and Yōrō rivers also empty into the water. The bay floor is mostly flat in many places. One area called Nakanose is quite shallow. North of that area, the water is deeper.

The bay has changed names many times over the years. In ancient times, people called it Edo Bay. Later, it was known as Edo Bay after the city of Edo. In 1868, the Imperial court moved to Edo. They renamed the city Tokyo. Because of this, the bay took its modern name. This change happened during the modern era of Japan.

People have built many new islands in the bay. This is called land reclamation. They use sand from the bay floor to make new land. There is only one natural island called Sarushima. It was once a fort but is now a marine park. Other islands like Odaiba were built for protection. Now, Odaiba is a place for fun and business.

Some islands, like Yumenoshima, were even used to hold garbage from the city.

Tokyo Bay has played a big part in world history. In 1853, Commodore Matthew Perry sailed his "Black Ships" into the bay. This led to a peace treaty with the United States. Later, the bay saw the end of World War II. On September 2, 1945, a famous treaty was signed. It was signed on a ship called the USS Missouri. This ship was anchored right in the bay. Today, the bay remains a very busy place for ships and industry.
