Watatsumi

The existing description already gives Watatsumi's two credited acts as sea king in the Hoori story, summoning every fish to recover the lost fishhook and seating his guest with ceremony before a word is spoken. That figure, the sea king who rules an undersea palace and gives his daughter Toyotama-hime in marriage, is not the only Watatsumi the tradition records. The Nihon Shoki also names three separate Watatsumi deities, Sokotsu-Watatsumi, Nakatsu-Watatsumi and Uwatsu-Watatsumi, born not from a courtship story at all but from Izanagi's own purification in the sea after his return from the land of the dead, in the same rite that produced the three Sumiyoshi gods worshipped as patrons of sailing and of poetry at Sumiyoshi Taisha in Osaka. Some later shrine traditions read this triad and the single palace-dwelling sea king as the same figure described two ways; others keep them distinct, an unsettled point this record does not resolve either way. What is not in dispute is that the Watatsumi name in the corpus covers both a cosmological triad born at creation's edge and a single personal sea king who hosts a mortal's son, and a reader who has only met the palace and the fishhook has not yet met the whole of what the texts call by that name.

The existing description already names Kaijin Jinja on Tsushima Island as a shrine where Watatsumi is worshipped today, and his living veneration goes further than that single site. Shikaumi Jinja, on Shika Island in Fukuoka Prefecture, stands as the head shrine of the whole Watatsumi shrine network, a currently functioning religious institution rather than a museum piece, and it is the ancestral shrine of the Azumi, a historical seafaring clan whose own genealogy traces its descent directly from Watatsumi through his son Utsushihikanasaku. The Azumi were a real maritime people of ancient Japan, not a mythic invention, and the clan's documented history of navigation and fishing across the Genkai Sea is inseparable in the shrine's own telling from its founding god. Shikaumi Jinja's annual festivals continue to draw the shrine's parishioners and visiting worshippers today, maintaining an unbroken line of institutional worship whose founding the shrine itself dates deep into Japan's early history, well before written record. Between Kaijin Jinja's local devotion on Tsushima and Shikaumi Jinja's standing as head shrine of an entire network with a named historical clan behind it, Watatsumi's living veneration is not confined to one shrine or one story but spans a real institutional structure still operating in Japan today.
