From Sakurajima’s ferry port terminal you want to exit the left side towards the Kagoshima Sogo Shinkin Bank. From there you should turn in left and walk up a steep slope towards the Dinosaur carpark. It was very quiet when I arrived and the weather felt great!! There were a many dinosaur statues and slides for the kids. There were also animal statues like lions and pandas. It was quite a cute playground and there are picnic tables around.
