I always felt that a castle is a place where we are able to learn the history of the place and be able to see the intelligence of the past. It is a great place to spend your afternoon, there will be some events in the weekends like performance or magic show around which is quite interesting. For the ticket price is worth the cost because you are able to see a lot of things and not only the top view from the Nagoya castle but also the construction of the castle, some photoshoot area and a place where they show the street of Edo period.
