Pack a picnic and enjoy a fun family day out at Kiyosato Highland Park. There's plenty of space for the kids to run about and get some fresh air.
You'll have no end of sightseeing choices in Hokuto. Kiyosato Highland Park is a good place to begin here, but there are many other worthwhile attractions to appreciate. Fujimi Kogen Ski Area, Chateraise Ski Resort Yatsugatake, and Nakamura Keith Haring Collection are close to the outdoor recreational space and will fill in your day nicely.
