A word of advice. Have a good breakfast/brunch/lunch before leaving Nagano for Yamanouchi town. The town is pretty quiet and we hardly noticed any food joints. If you intend to stay the whole afternoon there (park closes at 4.00pm), bring some food along. If you need to eat at the park, go to the visitor's center. There is also a warning telling visitors not to eat inside the park....not unless you want a 100 monkeys surrounding you.
We left the park around 2.00pm for our bus ride back to Nagano. Spent time there having a quick ramen, some sight seeing before catching the train back to Tokyo.
