History of Tokyo Bay

Tokyo Bay, once known as Edo Port, served as an important distribution hub supplying daily goods to the people of Edo (old Tokyo).

In the mid-19th century, when Japan opened to the world, five ports were designated as international trade ports: Hakodate, Yokohama, Kobe, Nagasaki, and Niigata.

However, Edo was not opened for national defense reasons, missing the opportunity to develop as a modern foreign trade port.

After the Great Kanto Earthquake, modern port construction began. Wharves such as Hinode, Shibaura, and Takeshiba were built, and Tokyo Port gradually developed into a major harbor. In 1941, it was finally opened to foreign trade.

During the global container shipping revolution of the 1960s, Tokyo Port quickly adopted container transport. In 1967, Japan’s first full container ship entered Shinagawa Pier, marking a major step in Tokyo Port’s development as an international trading port.

The Third Battery is the best-preserved of the original Odaiba fortifications and is now open to the public as Daiba Park.


Here, visitors can walk inside the former fortress and see the original stone walls that once supported cannons facing Tokyo Bay. Although the batteries were never used in battle, they symbolize Japan’s urgent efforts to strengthen its coastal defenses during the final years of the samurai government.


Today, Daiba Park offers a fascinating contrast between Edo-period military history and the modern skyline of Tokyo Bay.

After crossing the Rainbow Bridge, we explore Odaiba’s lively waterfront shopping and entertainment area, including Decks Tokyo Beach and Aqua City Odaiba. These popular complexes offer a wide variety of shops, restaurants, cafés, and entertainment facilities overlooking Tokyo Bay.

Inside Decks Tokyo Beach, we can visit the nostalgic Daiba 1-chome Shotengai, an indoor shopping street that recreates the atmosphere of Japan in the 1950s and 1960s. The retro-style streets are lined with vintage signs, small shops, and traditional candy stores, offering a fun glimpse into Japan’s Showa-era culture.

Decks Tokyo Beach is also home to the Odaiba Takoyaki Museum, where several famous takoyaki shops from Osaka gather in one place. Here visitors can try different styles of takoyaki, the popular Japanese street food made of batter balls filled with octopus and topped with savory sauce.

From the rooftop Seaside Terrace and nearby waterfront areas, visitors can enjoy beautiful views of Tokyo Bay and the Rainbow Bridge, making this a perfect place to relax, explore, and take photos during our Odaiba visit.

Open weekdays 11:00–19:00, weekends and holidays 10:00–19:00.

Enjoy coffee in partnership with Nespresso, along with light meals such as toast and sandwiches. Visitors interested in BMW showrooms in Japan will enjoy a stop here. If preferred, we can skip the café and continue through DiverCity Tokyo Plaza’s shopping area.

Explore cutting-edge robotics, space technology, and interactive exhibits that make science fun for all ages. It’s a fascinating experience for anyone curious about the future of science and innovation.
