Oasis 21 is a major hub for transport, shopping and also a scenic city park spot in the city of Nagoya in Aichi prefecture. The hub consists of many underground restaurants and shops alongside a major bus terminal for all your inner-city and outer-city transport needs. Coupling this with being located adjacent to the Nagoya TV Tower makes it a great light-up spot at night. The distinctive large oval shaped glass structure at the top of the building has a thin film of water spanning it's entirety making for interesting visual effects while also having a cooling affect during the hot summer months.
