Little Place of Kamaruddin

Japanese Shinto priests first wed these two hulking rocks off the coast of Futami more than 1,300 years ago to symbolize the sanctity of marriage. Today, husband rock (the strong, silent type at 30 feet high) and wife rock are still yoked together in the Pacific Ocean by 100 feet of braided rice straw, which is replaced three times a year. (The priests do that at low tide, when the rocks aren’t separated by water, and worshippers join in the ceremony by handing the rope from person to person onshore.) In the summer, the scene is perhaps most divine: The sun appears to rise between the two points, with Mount Fuji visible in the distance.

The two wedded rocks are called Meoto Iwa (Husband-and-wife rocks)
