Oasis 21 is a park in the downtown area of Nagoya. Having bus stops, shops, restaurants, and other facilities, it is a popular open area for the public. Around the park there are buildings such as the Nagoya Castle, the TV Tower, art galleries, and large department stores. In the distance, Oasis 21 looks like a spaceship floating in air. With water flowing down from a dozen meters above from the glass roof, it is a dazzling sight in the middle of bright night lights.
