Inyoseki Shrine
One of the oddest sights in all of Miyazaki , this shrine boasts a rock naturally shaped like a phallus. There’s also a small museum (enter at your own risk). Back in its day it was a great attraction for newly-weds and those trying to have kids. Free entry.

Suki Murando Horse and Dolphin Farm (すきむらんど)
Contrary to the name, there are no horses or dolphins here. Instead, you’ll find a quaint little art gallery with 3 annexes: craft, photography, and art. In addition to the gallery, you’ll find an unagi restaurant, a hiking trail, an onsen, and even summer canoe rentals!

Mamako Waterfall (須木の滝) (map)
Legend has it that a mother jumped over the fall with her child, hence the name “Mother and Child.” Despite the sad story, this fall is a very beautiful sight.
