Worth the trip as this castle is full of good history in many points. The castle is filled with exhibits on every level so there on't be a bored moment. The grounds is well kept and photo ops are at several majestic spots.
Another little treasure in Saitama. Not all of the complex is original and most has been rebuilt. The grounds are well kept with many sitting areas to enjoy the views. To enjoy the castle grounds is free but the on site museum building costs ¥200 to enter.
It was closed when I arrived, so couldn't go inside. Finally can only see from the outside. This castle was built on a very large land. The Castle building is still there, standing strong and strong.

Note: parking available
The castle grounds and the surrounding areas are free to tour and walk around. They are well kept, have some aesthetic areas for photos and some seating areas to enjoy the peaceful nature of this place. Dogs are also welcomed.
Attached to the main castle grounds area is a museum but that does have an entry fee and as I am not wanting to spend much I chose not to go.
Overall the place is well preserved but quick to tour if not going to the museum. You can walk around the property in about 10 minutes I would assume the museum adds some time to it.
