Saigo Park is a pleasant place to take a breather. Have a picnic, throw a ball around or just lie on the cool grass and close your eyes for a while.
This recreation and green space is in Kirishima, a destination that has so much on offer! Myoken Hot Springs, Kagoshima Airport Observation Tower, and Kagoshima Shrine are other worthwhile sightseeing options nearby when you've finished up at Saigo Park.
