It's a beautiful place! I really liked it! It's picturesque. I found the trash cans at the vending machines. It was a great show. Even on weekdays, there are a lot of people (even Russians were met), they are not allowed inside. Class
You can go and admire it if the guide is good. They are not allowed inside. Glass elevators and air conditioners have already been slapped on the inside of the courtyard - well, so… If you are lucky, you will come across a performance by street performers on the territory of the complex. Beautiful photos are taken from the side of the pond.
There is a cafe.
Remember that there are no trash cans.
The castle is in classic Japanese style, a picturesque view of the moat with water, a large park area, a panoramic view of the city from the observation deck of the castle.
It's beautiful, but nothing unusual (there are many more interesting places in Japan). If you find yourself in Osaka, it is definitely worth visiting, but you do not need to go to Osaka from another city specifically for this castle.
Visiting the park and the surrounding area is free; entrance to the museums and the observation deck of the castle is about 700 yen (by the way, the panoramic view from the Umeda Sky Building is much better, it is better to visit the observation deck there)
