Red Gate

The red gate links the real world with the magic land. Through the gate, the Ogino family arrives at Yubaba's island of Yūya. When the night breaks, the red gate becomes the lighthouse of a harbor

Architecture
At the entrance of the human world is a two-faced Dousojin statue. A little further away are small houses for the kami. The outer walls of the gate are painted red. The building is maintained in the Kawagoe style [2]. A tunnel leads through to the Spirit Realm.

Closure
After the family Ogino has safely gone through the gate and so has left the magic land again, she finds her car overgrown by plants. Even the face of the Dousojin statue is not recognizable and covered by moss.

This shows that many years have passed, even though Chihiro apparently worked only three days in the bathhouse. Since the face of the statue is unrecognizable, probably 100 years have passed. The rapid aging can also be caused by the magic that was cast when the gate was closed.
