Lovely place to spend half a day. Bonsai garden. Japanese garden, with optional Japanese sweet and matcha tea for 700 yen at the teahouse. Small Komorebi folk village with a traditional farm house and agriculture displays. Worth spending 400 yen for the park train for at least half the excursion (e.g. to return to your entry point). Nice places for picnics (e.g. children's forest). Went mid-week, was nice and quiet.
