Tracing the sun-drenched coastal highway of the **Nichinan Coast** in southern Miyazaki Prefecture leads to one of Japan's most visually dramatic and spiritually enchanting Shinto sanctuaries: **Udo Jingu Shrine**. Defying ordinary Shinto tradition where worshipers ascend toward mountain summits, reaching Udo Jingu requires descending a steep flight of vermilion-lacquered cliffside stone staircases that cling precariously to basalt sea walls directly above the thundering breakers of the Pacific Ocean. At the foot of the cliff, the path disappears into a colossal natural sea cavern spanning roughly 1,000 square meters, hollowed out of the headland by millennia of relentless ocean swells. Deep within this cavern's cool, shadowy expanse stands the vibrant vermilion **Honden** (Main Sanctuary), painted in brilliant lacquer that glows warmly under strings of paper lanterns. According to ancient *Kojiki* mythology, this sacred cave was the birthplace of Ugayafukiaezu-no-Mikoto, the father of Japan's legendary first emperor, Jimmu. Inside the cavern, two breast-shaped stalactites known as *Ochichi-iwa* (Breast Rocks) continuously drip pure water, revered as a blessing for safe childbirth, fertility, and marital harmony. The quintessential pilgrimage ritual at Udo Jingu is the exhilarating **Undama Lucky Ball Toss**. Visitors purchase five small clay discs stamped with the character for luck (*un*). Standing upon the outdoor cliff railing, worshippers attempt to pitch the clay balls down into a circular depression marked by a sacred straw rope (*shimenawa*) atop the **Kameishi** (Turtle Rock)—a giant turtle-shaped sea crag surrounded by crashing waves. Legend dictates that men must throw with their left hand and women with their right; successfully landing a clay sphere into the hollow ensures that your deepest personal wish will be granted by the maritime deities.
