Nagoya Castle... I mean, Nagoya Museum in the shape of a castle, is a 6 floor sweltering hot place for tourists. Even cooler than entering the castle is the entire castle grounds, which are comprised of a; Noh theater museum, doll museum, gift shop / cafeteria, flower garden, woodland moss garden, cultural garden, and teahouse. The castle complex costs about Y500 per person to enter.
The top floor of the castle is an observatory with a gift shop in the middle. You do not need to remove your shoes to enter the main castle. But, you will be asked to remove your shoes and put them in a locker if you enter the Royal Palace home separately. It was a little confusing at first, because the castle entrance is around the back of the building. Next to the ice cream and tofu donut vendor.
When visiting, make sure to walk the entire complex and not miss a thing. I really regret not stopping at the teahouse on the way out, because the menu looked really awesome. Since this is Nagoya, even the most touristy of area are not that busy in the morning.
I really like how most of the cultural spaces in Nagoya are condensed into this one complex, so it makes it much easier to visit than, let's say, Osaka Castle. It is also very easy to access from the subway system. But, seriously, we just walked here all the way from Nagoya Station (main station) with no issue.
Nagoya is not a large city, so it is easy to walk across most of downtown in about 30 minutes.
