We checked out the Osaka castle to see what we hoped would give us a feel for what an old Japanese castle looks like. We were hugely disappointed to find that the entire inside of whatever it used to look like hundreds of years ago has been ransacked and remade into a museum. There are PLENTY of museums in Japan and it's a real shame that this is all the castle has become. I would have loved to see what an old Japanese castle looks like. The exhibits were not very interesting except for two Japanese soldier costumes. You cannot take any photos while inside. Nice views from the top but besides that I would save your 600 yen and enjoy it from where it looks most like an old Japanese castle - from OUTSIDE!
