JR TOWER is the station building which has the entrance of Sapporo Station. This building consists of the tower part, the central part and the department store part. This building contains a hotel, a department store, a cinema complex, several clinics and offices and four shopping malls containing many shops and restaurants.
It is quite convenient to go shopping or have meals in this building since it is connected to the station. Especially, it is a big advantage to be able to hang out in shopping malls without going outside on a rainy or cold day.
However, this building is too big and complex to understand perfectly. There are hundreds of entrances and exits in this building. It is easy to go into the building, but it is quite difficult to escape from exit which I want.
