About Osaka Bay

Osaka Bay, also known as Settsu Kai, has been a center for international trade and a naval harbor. The bay has seen the development of port facilities and modern attractions that attract millions of tourists each year.

During the Edo period, Osaka grew as a merchant city, with Osaka Bay facilitating the distribution of goods. The Meiji Restoration heralded the modernization of Japan, transforming Osaka Bay into a significant international port with the Port of Osaka’s opening in 1897.

The 20th century saw further expansion and modernization of Osaka Bay. World War II and the ensuing reconstruction shaped the bay, which adapted to handle larger vessels and a broader range of cargo.

Today, Osaka-ko is known for its economic role and recreational and cultural venues. The Osaka Aquarium Kaiyukan is one of the world’s largest public aquariums, displaying marine life from the Pacific Rim. The Tempozan Giant Ferris Wheel provides panoramic views of the bay and the city, especially at night.

The Universal Studios Japan theme park, with rides and entertainment based on popular movies, is also in the bay area. These historic and modern elements make Osaka Bay a unique and dynamic destination.

Visitors to Osaka Bay can enjoy the promenade for scenic walks and discover the Naniwa Food Theme Park for a taste of Osaka’s street food in a nostalgic setting.

Osaka Bay embodies Japan’s maritime heritage while evolving as a center for entertainment and culture, offering a blend of historical and contemporary attractions.
