Go for a walk or have a picnic on the grass at Iwamotoyama Park. You can make your own fun at this sprawling recreational area.
You're spoiled for sightseeing choice when in Fuji. Iwamotoyama Park is a good place to kick off here, but there are lots of other fine sights to explore. Mt. Fuji World Heritage Center, Fujisan Hongu Sengen Taisha Shrine, and Fuji Sky View Ferris Wheel are near the outdoor recreational space and will top off your day nicely.
