In the Osaka City is the Osaka Castle with a five-layer donjon as its core, on a lawn park that stretches for about 60,000 square meters. During the cherry blossom season in the spring, this park is especially crowded with hanami (cherry blossom viewing) crowd. Osaka's north gate, Umeda, has a gigantic stretch of underground mall that houses many restaurants, fashion and sundry goods stores.
In contrast to Kita with Umeda as its core, Minami is an area with core cities Namba, a popular business and shopping district, and Dotonbori with many restaurants on both sides of Dotonbori-gawa River. Minami is known as a town of public entertainment and has many theaters and cinemas.
Tenpo-zan Harbor Village, which has a 112.5 meter-high Ferris wheel, shopping mall and Kaiyukan Aquarium, one of the biggest aquarium in the world, and ATC(Asia Pacific Trade Center), Japan's largest outlet mall, are also popular.
