Very well maintained and cheap to enter (¥500), these gardens were a great way to close off a day. While I didn't get to see the spring cherry blossoms or full array of Autumn colours, there was still plenty to look at and enjoy. There is a section of native plants, foreign plants, japanese gardens, rose gardens, bonzai exhibits, cherry blossoms, acorns, ume and many others, as well as various ponds and streams. Very calm and tranquil - I only had about 70 minutes to spare here, and I'd love to come back and see more someday.
