Tomioka Hachimangu in Kanazawa Ward, Yokohama, said to have been founded by Minamoto no Yoritomo

Tomioka Hachimangu Shrine in Kanazawa Ward, Yokohama, is the guardian shrine of the Tomioka area, said to have been founded by Minamoto no Yoritomo, and is recognized as the original shrine from which the famous Tomioka Hachimangu in Fukagawa, Tokyo was established. Its alternate name, “Namiyoke Hachiman” (wave-repelling Hachiman), evokes the shrine’s legendary power to protect the community from a great tsunami, making it an ideal starting point for a historical walk through Yokohama.

What Kind of Shrine Is Tomioka Hachimangu? — Origins and Deities

Ebisu, Invited by Yoritomo, Is the Foundation

The founding of Tomioka Hachimangu dates to the Kenkyu era (1190–1199). According to tradition, Minamoto no Yoritomo enshrined the Hiruko deity (Ebisu, of the Nishinomiya Shrine lineage) from Naniwa in Settsu Province. After establishing the Kamakura shogunate, Yoritomo is believed to have recognized the strategic importance of placing a shrine on the heights of Tomioka, overlooking the waters of Tokyo Bay.

Subsequently, during the Antei era (1227–1229), Hachiman (Hachiman Daijin / Emperor Ojin) was enshrined alongside Ebisu. Since then, the two deities — distinct in character — have been venerated together. The three deities currently enshrined are Hachiman Daijin, Hiruko no Mikoto (Ebisu), and Amaterasu Omikami.

The Origin of “Namiyoke Hachiman” — The Tsunami Legend

The Great Tsunami of the Ocho Era and the Shrine’s Hill

Tomioka Hachimangu bears the alternate name “Namiyoke Hachiman” (wave-repelling Hachiman). This name originates from a great tsunami said to have struck around the Ocho era (c. 1311). The legend holds that the hill on which the shrine sits acted as a natural barrier, shielding the Tomioka settlement from devastating waves. This story took root in the local community, and the shrine became revered for protection from tsunamis, disasters, and sea dangers by fishermen and sailors.

Edo-Era Reverence and the Shrine Precinct

The reputation of Namiyoke Hachiman spread as far as Edo during the Edo period, attracting worshippers by both sea and land. The precinct retains the main hall, worship hall, and kagura hall, said to have been built in the mid-Edo period, conveying the shrine’s historical dignity through understated wooden architecture. A great camphor tree (kusunoki) estimated to be several hundred years old stands in the precinct, allowing visitors to feel the ancient character of the sacred space. During the grand spring festival (April), a mikoshi procession (shinko) passes through the community, offering a vivid glimpse of living local faith.

The Relationship with Fukagawa’s Tomioka Hachimangu — Why Yokohama Is the “Original”

The Division of the Spirit in Kan’ei 4 (1627)

Many visitors to Tomioka Hachimangu in Koto Ward, Tokyo may not realize that Yokohama’s Tomioka Hachimangu is the original shrine (honsha). In the early Edo period, when land reclamation work in Fukagawa under Tokugawa Iemitsu met with repeated difficulties, the Tomioka Hachimangu in Sagami Province — this very shrine — was invoked as the local tutelary deity and its spirit was transferred to Fukagawa. Fukagawa’s Tomioka Hachimangu was thus founded in Kan’ei 4 (1627) from that act of enshrinement.
