WWII had a dramatic impact: vast areas of the city were flattened and the infrastructure destroyed. Osaka has evolved as a modern city with a lively spirit, although little remains of its past and there are few historical sites to see. Most of the old waterways and traditional wooden buildings have disappeared and the skyline is now dominated by tall and gleaming office blocks. Osaka represents modern Japan and it is the best place to eat, drink and party. The choice and quality of restaurants is as good as anywhere. It remains a merchant city and the different districts each have their own speciality. The clan continued to occupy the castle until 1867 when they were forced to support the Meiji Restoration. The castle was reconstructed using stone in 1931, and bears little resemblance to the original structure. Osaka Aquarium (Kaiyukan): is considered to be the best aquarium in Japan and one of the largest in the world. There are 15 tanks spread over several floors, each representing a different environment and containing a wide variety of marine life. The main attraction is the huge central tank that focuses on the Pacific Ocean and includes a whale shark. The aquarium is located in the Tempozan harbour village of Osaka's port area. Umeda Sky Building: is a 173-metre-tall building and city landmark. It comprises of two main towers that are connected at the top by the Floating Garden Observatory. The rooftop observatory has impressive views across Osaka, particularly at night. The basement features the Takimi-koji restaurant mall and a replica of a Meiji-era street, complete with restaurants and bars. |
