The gates and entrances to the buildings are quite beautiful. You can't take photos inside any of the buildings. I'm not sure why as all the paintings inside are replicas. All the actual art was in the building I mentioned earlier that was closed. The building itself is authentic. The wooden floor boards squeak and sound something like bird sounds. You do have to take your shoes off - there is no heat. Trust me - we did not dawdle looking at fake paintings!
There are a couple of gardens in the castle area. Of course there are plum trees and cherry trees. The plum are the ones in blossom. Gardens are the one thing that H and I agree are beautiful and would warrant another trip to Japan. Maybe a tourist train, Japanese garden trip in May or September!
