Castle admission is an additional 1,000jpy.
Osaka and Himeji Castles are incomparable.
Not really into visiting a castle but as that's the most popular in Osaka, I'm just going there for fun and take pictures with my friend. If queues are too long, we will probably not bother going inside the castle. However, I'm most interested for the Osaka-jo Gozabune Boat ride. The Osaka Castle looks more or less like the Nagoya castle (I have been inside Nagoya castle in 2010).
