It is impressive, but not during the summer especially not in rainy season. There's not much to see but at least it is free. There are even black cats that walk around the ruins. The paved floor is very very slippery so be careful.

Amazing to glimpse into over 400 years of history! It was lovely to admire not just the beautiful architecture and construction, but the beautiful views from the high ground. There are quite a few parts of the ruins scattered across the site and I kind of regret not seeing more.

It was nice and peaceful and quite beautiful seeing the sakura in the dim lighting. However, there were too many people and the line to enter the area of the castle when it's lighted is incredibly long, at least an hour of wait. But you can still see the lit castle while walking through the sakura trees below.

If you’re in the area and enjoy walking and history, you’ll love this. I very much enjoyed this detour in our day. Added another few thousand steps to our day. It was very interesting and beautiful. Also- cherry blossoms if in season.

Interesting little castle on a hill, can't get all the way to it due to renovation but nice quick views of the city and just interesting to pull up Wiki and read about the history. So many people came before us and will come after us, fascinating to contemplate.
In spring, arrive early for cherry blossoms framing the stone walls. In autumn, enjoy colorful leaves around the moats. Check the park website for occasional evening illumination events.
