The
Kojiki version of the Japanese creation myth honorifically refers to Watatsumi 海神 with the name Ōwatatsumi kami 大綿津見神 "Great Watatsumi god". Compare this sea god with mountain god named
Ohoyamatsumi 大山積. The world-creating siblings
Izanagi and
Izanami first give birth to the Japanese islands (
kuniumi) and then to the gods (
kamiumi). When they had finished giving birth to countries, they began afresh giving birth to Deities. So the name of the Deity they gave birth to was the Deity Great-Male-of-the-Great-Thing; next they gave birth to the Deity Rock-Earth-Prince; next they gave birth to the Deity Rock-Nest-Princess; next they gave birth to the Deity Great-Door-Sun-Youth; next they gave birth to the Deity Heavenly-Blowing-Male; next they gave birth to the Deity Great-House-Prince; next they gave birth to the Deity Youth-of-the-Wind-Breath-the-Great-Male; next they gave birth to the Sea-Deity, whose name is the Deity Great-Ocean-Possessor; next they gave birth to the Deity of the Water-Gates, whose name is the Deity Prince-of-Swift-Autumn; next they gave birth to his younger sister the Deity Princess-of-Swift-Autumn. (tr. Chamberlain 1919:28) Chamberlain (1919:30) explains
mochi 持ち "having; taking; holding; grasping; owning" behind translating Ōwatsumi kami as "Deity Great-Ocean-Possessor", "The interpretation of
mochi, "possessor," though not absolutely sure, has for it the weight both of authority and of likelihood." A subsequent
Kojiki passage describes Watatsumi's daughter Otohime and her husband
Hoori living with the sea god. After Hoori lost his brother
Hoderi's fishhook, he went searching to the bottom of the sea, where he met and married the dragon goddess Otohime. They lived in the sea god's underwater palace
Ryūgū-jō for three years before Hoori became homesick. So he dwelt in that land for three years. Hereupon His Augustness Fire-Subside thought of what had gone before, and heaved one deep sigh. So Her Augustness Luxuriant-Jewel-Princess, hearing the sigh, informed her father, saying: "Though he has dwelt three years [with us], he had never sighed; but this night he heaved one deep sigh. What may be the cause of it?" The Great Deity her father asked his son-in-law saying: "This morning I heard my daughter speak, saying: 'Though he has dwelt three years [with us], he had never sighed; but this night he heaved one deep sigh.' What may the cause be? Moreover what was the cause of thy coming here?" Then [His Augustness Fire-Subside] told the Great Deity exactly how his elder brother had pressed him for the lost fish-hook. Thereupon the Sea-Deity summoned together all the fishes of the sea, great and small, and asked them, saying: "Is there perchance any fish that has taken this fish-hook?" So all the fishes replied: "Lately the
tahi has complained of something sticking in its throat preventing it from eating; so it doubtless has taken [the hook]." On the throat of the
tahi being thereupon examined, there was the fish-hook [in it]. Being forthwith taken, it was washed and respectfully presented to His Augustness Fire-Subside, whom the Deity Great-Ocean-Possessor then instructed. (tr. Chamberlain 1919:149) Watatsumi instructs Hoori how to deal with Hoderi, and chooses another mythic Japanese dragon, a
wani "crocodile" or "shark", to transport his daughter and son in law back to land. Two
Nihongi contexts refer to Watatsumi in legends about
Emperor Keikō and
Emperor Jimmu. First, the army of Emperor Keikō encounters Hashirimizu 馳水 "running waters" crossing from
Sagami Province to
Kazusa Province. The calamity is attributed to the Watatsumi 海神 "sea god" and placated through
human sacrifice. Next he marched on to Sagami, whence he desired to proceed to Kadzusa. Looking over the sea, he spake with a loud voice, and said: "This is but a little sea: one might even jump over it." But, when he came to the middle of the sea a storm suddenly arose, and the Prince's ship was tossed about, so that he could not cross over. At this time there was a concubine in the Prince's suite, named Oto-tachibana-hime. She was the daughter of Oshiyama no Sukune of the Hodzumi House. She addressed the Prince, saying: "This present uprising of the winds and rushing of the waves, so that the Prince's ship is like to sink, must be due to the wishes of the God of the Sea. I
pray thee let me go into the sea, and so let the person of thy mean handmaiden be given to redeem the life of the Prince's Augustness." Having finished speaking, she plunged into the billows. The storm forthwith ceased, and the ship was enabled to reach the shore. Therefore the people of that time called that sea Hashiri-midzu. (tr. Aston 1896:206) Second, the genealogy of Emperor Jimmu claims descent from the goddess
Toyotama-hime, the daughter of Hori and Otohime, who is identified as the daughter of Watatsumi 海童. The Emperor Kami Yamato Ihare-biko's personal name was Hiko-hoho-demi. He was the fourth child of Hiko-nagisa-takeu-gaya-fuki-ahezu no Mikoto. His mother's name was Tamayori-hime, daughter of the Sea-God. From his birth, this Emperor was of clear intelligence and resolute will. (tr. Aston 1896:109-110) There is uncertainty whether
Nihongi scribes wrote
tsumi with
dō 童 "child; boy" simply for pronunciation or for some semantic significance. ==Watatsumi Sanjin==
