Very crowded, a bit akward how every meter people are waiting in line to pose for photos. A lady was upset at us for sitting on a bench next to the water and a cherry blossom tree "because that is the photo bench. You need to use it to quickly pose and then let others have a turn". There are no signs stating anything like that and there are a ton of benches spread throughout the park. Most bizarre experience.
