Some may charge, some may be free but you'll find plenty to see and enjoy as you take a rest from the hectic pace outside of the garden. Go hiking. Provided you can get to the good hiking locations, this can be a very affordable way to see more of Japan. The huts on hiking trails tend to be priced reasonably and there are amazing things to see, from volcanoes on Japan's southern island of Kyushu to the peaks of the Japan Alps in Central Honshu.
