The magma, poured out about 1500 years ago, has been eroded by the sea to form these rocky pillars in the ocean. 40 of them stand along from south to east in a 850m-long line.
The name derived from the appearance of bridge piers without the deck. The artistic scenery created by nature can be called Wakayama’s top tour spot and is designated as a national natural monument.
You can enjoy the view from the shore or walk up close to the rocks when the tide is low. Around the center of the row of rocks, there is Benten Island covered by a grove with a small shrine gate cueing where the god of the sea, Hiruko Daimyojin, is honored.
The rock piers are not only an interesting tour spot, but also have a variety of legends. One of the unique stories is that Reverend Kobo competed with a demon in building a bridge. Kobo created the rock piers overnight, but the demon’s trick prevented him from finishing the deck and he walked away unfinished.
After exploring, stop by Michinoeki Kushimoto Hashiguiiwa, a souvenir shop, by a parking lot and look at local products.
