Namikiri Shrine 波切神社
In the Namikiri cave, legend has it that Kōbō Daishi, returning from Tang China, parted the stormy waves to protect the ships, an episode still remembered in the name 波切 (‘wave-cutter’) and in a statue of Fudō Myōō kept in the cave.
波切神社 (Namikiri Jinja) is a secondary shrine (境内社) of Udo Shrine (鵜戸神宮), in Nichinan, Miyazaki Prefecture. It stands in a sea-carved cave on the north side of the Udo promontory – ‘海が間近に迫る洞窟の中’ (kanko-miyazaki.jp) – reached by a mountain path of about 15–20 minutes that branches off beyond the Inari Shrine, inside the grounds of Udo Jingu (鵜戸神門をくぐり、鵜戸稲荷神社へ続く階段を登るとある波切神社へ続く約20分の参道; 鵜戸神宮から波切神社までは歩いて15分程, pmiyazaki.com). The Japanese Wikipedia records that the original name was Buddhist, 波切不動尊, changed to 波切神社 during the Meiji-period policy of separating Shinto and Buddhism (廃仏毀釈). The coordinates given here come from a KML file of a Google My Maps map created by a user (not an official body), titled exactly ‘鵜戸神宮波切神社’, with a placemark about 700 m from the generic address of the whole Udo Jingu complex (〒887-0101 宮崎県日南市大字宮浦3232): a distance consistent with the 15–20 minutes of path reported by the official sources, but the accuracy of the coordinate does not carry the same weight as an institutional source.
