It's common knowledge that spending a couple of hours surrounded by greenery can increase your energy. If roaming around town has tired you out, Senbonhama Park is a perfect spot to stop and recharge your batteries.
Situated in Numazu, this recreation and green space is worth a visit. But you'll find plenty more to see in the area. Izu-Mito Sea Paradise, Awashima Marine Park, and Numazu Deep Blue Aquarium aren't too far from Senbonhama Park.
