Shirozu Lake

 This is the dam which created the lake. The observatory is behind the trees on the right.

 I stopped to look at some ducks and they seemed to think that I was going to feed them. However, I had nothing with me. The next time I plan to go to the park, I will try to remember to bring some bread for them.

This is the walking path along the north side of the lake. The building seems to be a large private home. Every few hundred meters along the path there were gazebos and benches.
