Watatsumi (or Ōwatatsumi-no-kami, lit. "great god of the sea") is a prominent deity in Japanese mythology, primarily revered as a god of the sea and water. He is often identified with Ryūjin, the dragon god, and is depicted as the ruler of the oceans, currents, and all marine life.
Overview Watatsumi is one of the most important kami (deities) associated with the aquatic realm in Shinto belief. His dominion extends over the vastness of the sea, controlling its tides, waves, and creatures. He is frequently portrayed as dwelling in a magnificent undersea palace known as Ryūgū-jō (Dragon Palace), which is said to be built from coral and crystal.
Etymology and Forms The name "Watatsumi" literally translates to "sea god" or "sea spirit." While often used generically for sea deities, the specific kami is frequently referred to as Ōwatatsumi-no-kami (大綿津見神 or 大海津見神), emphasizing his supreme status among sea gods. He is sometimes considered a collective term for a group of three sea gods (Watatsumi Sanjin), though Ōwatatsumi is the principal figure.
Mythology and Role Watatsumi plays a significant role in several foundational Japanese myths, particularly those found in the Kojiki and Nihon Shoki.
- Birth: In some accounts, Watatsumi is born from the purification rituals of Izanagi, the primordial deity, after his return from Yomi (the underworld). As Izanagi washes his body, various kami are born, and Ōwatatsumi-no-kami emerges when he washes his middle body.
- Hoori and Toyotama-hime: One of the most famous myths involving Watatsumi is the story of Hoori (Yamasachihiko) and his quest to retrieve a lost fishhook from his brother Hoderi (Umisachihiko). Hoori journeys to Watatsumi's undersea palace, where he meets and marries Watatsumi's daughter, Toyotama-hime. Watatsumi assists Hoori in recovering the hook and provides him with magical jewels (the Shiomitsu-tama or tide-flowing jewel, and the Shiohiru-tama or tide-ebbing jewel) to control the tides, enabling Hoori to overcome Hoderi. This lineage is crucial as their son, Ugayafukiaezu, is considered the father of Emperor Jimmu, the legendary first Emperor of Japan.
Worship and Shrines Watatsumi is widely worshipped across Japan, especially in coastal regions and by those involved in fishing and maritime industries. Many Shinto shrines are dedicated to him, often referred to as Watatsumi Jinja or Ryūjin Jinja. These shrines pray for safe voyages, abundant catches, protection from natural disasters, and prosperity. Prominent shrines include those on Tsushima Island and various locations in Kyushu.
Cultural Significance As a powerful and benevolent deity controlling the sea, Watatsumi embodies the respect and awe the Japanese people have historically held for the ocean. His myths reflect themes of harmony between humans and nature, the importance of balance, and the origins of the imperial lineage. The undersea palace Ryūgū-jō has become a classic motif in Japanese folklore and art, symbolizing a fantastical, inaccessible realm of wonder and power.
