Japanese castle? No way.

This picture was taken in Tennoji, Osaka when I got off the train at the Tennoji Station. If you want to see that like a castle, you will disappoint shortly. Actually, that is a mere hotel for couples. If you want to see a real castle, you need to go out to the Osaka castle or Himeji castle. That will be a precious experience for you. There is a large difference between real and fake.
