Tateiwa and the Four Sacred Rocks, a Hidden Power Spot on Suo-Oshima

In the Ageno-sho area of Suo-Oshima island stand four strange rocks long worshipped by islanders. Beginning with Tateiwa, an andesite pillar about 40 meters high rising from the coast, the journey around Ganmon, Iwaya Gongen, and Obiishi is called the pilgrimage of the four rocks for happiness, and it is said that praying at all four places brings good fortune. The majestic Tateiwa is also called the male rock and enshrines Bato Kannon.
