A short distance north in Tsuyama, lies Yokono Falls. Although it's not anything like Niagara Falls, it's still very beautiful and serene. It's a nice place to go just to relax. Their is also an interesting restaurant here. (Go to my "Restaurants" tips to read about it)
Take a walk (or drive, although I enjoyed the walk) up Mount Kannabi to the viewing tower. It's a nice place to relax and you can see most of Tsuyama from the tower. It's not far, and the walk is easy. It's like a slightly steep hill, so there's no mountain climbing involved. It's a small mountain! Mount Kannabi is a nice place to go to get out of the city for a little while.
