I think this is one of those posts where I’m going to let the pictures do most of the talking, because Nijo Castle is pretty remarkable.
I think most days you can go inside the castle itself, which I guess is like a museum of sorts? I was unlucky enough to show up on a day where the inside was closed, however the just the grounds around the castle are easily worth the 400 Yen admission fee.
I spent over an hour just wandering around and taking it all in.
The gardens are really impressive (and I’m sure they’d be even more impressive in the summer when all the leaves are still on the trees).
