Moro Shrine is a historic Shinto shrine located in Miwano-yama, Nagareyama City, Chiba Prefecture. The shrine was formerly known as Miwa Shrine and is regarded as one of the candidate shrines associated with the ancient Engishiki Jinmyocho, a record of officially recognized shrines compiled during the Heian period.
Moro Shrine has long been an important place of worship for the local community. Its history is closely connected with Omiwa Shrine and the ancient worship of Mount Miwa in Nara Prefecture, giving the shrine a distinctive historical and religious character.
Moro Shrine was originally called Miwa Shrine, a name derived from Omiwa Shrine in Nara Prefecture. The name “Moro” is thought to be connected with Mimoro-yama, the former name of Mount Miwa.
The elevated land where the shrine stands is also known as Miwa-yama or Miwano-yama. This connection between the place name and the shrine’s history suggests the area’s longstanding relationship with the worship of the deity of Mount Miwa.
The shrine is located in Miwanoyama, Nagareyama City, an area surrounded by greenery and historic sites. It is believed that the shrine once occupied a much larger sacred precinct during the Edo period, and traces of its former extent can still be found in the surrounding area.
The first torii gate stands at the entrance to Moro Shrine and marks the transition from the everyday world into the sacred grounds. Passing through the torii is traditionally regarded as entering the shrine’s sacred space.
Continuing along the approach, visitors reach the second torii gate. It leads farther into the grounds toward the central part of the shrine and adds to the sense of entering a more sacred environment.
The principal deity of Moro Shrine is Omononushi-no-Mikoto. The shrine’s tradition identifies its deity as a divided spirit, or bunrei, of the deity worshipped at Omiwa Shrine on Mount Miwa in Nara Prefecture.
Omononushi-no-Mikoto has traditionally been worshipped as a deity associated with the protection of the land and agriculture. The deity is therefore closely connected with prayers for fertility, abundant harvests, and prosperity, reflecting the agricultural traditions of the local community.
Moro Shrine is considered one of the candidate shrines for the “Moro Shrine” of Katsushika District in Shimousa Province, listed as a small shrine in the Engishiki Jinmyocho, a shrine register compiled in the Heian period.
There are also other shrines in Matsudo and Funabashi with the same name that have been proposed as candidates for the ancient Moro Shrine. Because of these competing theories, the exact identification of the shrine listed in the ancient record remains a subject of discussion.
The history of the deity associated with Moro Shrine can be traced back to ancient historical records. The “Nihon Sandai Jitsuroku” records that on November 12, 817, Moro-no-Kami was granted the Shinto rank of Junior Fifth Rank, Upper Grade.
Another record states that on September 25, 879, the deity was granted the higher rank of Senior Fifth Rank, Upper Grade. These records demonstrate that the worship of Moro-no-Kami was recognized within the religious and political system of ancient Japan.
The exact date when Moro Shrine was founded is unknown because no definitive record of its establishment has survived. However, the connection between its principal deity and Omiwa Shrine suggests that the shrine has an ancient religious background.
The elevated area where the shrine stands was historically known as Miwa-yama. The former sacred precinct is believed to have extended across a much wider area, including the site of a former jingūji temple, an old approach to the shrine, the former location of a torii in Nishi-Hirai, and place names associated with the Yagigō area.
In 1598, during the early Edo period, the Edo River was excavated and its course divided the former sacred area of Moro Shrine.
As a result, a branch shrine was established on the western bank of the Edo River during the Genna era. This branch became known as Miwa Shrine.
Moro Shrine also received an annual contribution of 25 koku of rice from the Tokugawa shogunate for religious ceremonies. This support reflects the importance attached to the shrine’s worship at the time.
The main sanctuary is the most sacred part of Moro Shrine and is dedicated to Omononushi-no-Mikoto. Its historic presence forms the spiritual center of the shrine grounds.
The worship hall is where visitors offer prayers. The roof tiles were replaced in 1995, helping preserve the building and maintain its appearance for worshippers today.
Within the shrine grounds are traces of a former jingūji, a Buddhist temple that once existed alongside the shrine during the period of Shinbutsu-shugo, or the historical blending of Shinto and Buddhism.
The remaining traces provide an opportunity to consider an important period in Japanese religious history, when Buddhist and Shinto traditions were closely interconnected.
One of the most distinctive traditions at Moro Shrine is the Jingara Mochi ceremony. It takes place on January 8 as part of Obisha, a traditional New Year ceremony associated with prayers for the year’s agricultural prosperity.
During the ceremony, a large kagami mochi rice cake is first offered before the deity. Parishioners then pull and tear the rice cake apart with their hands.
The way the rice cake breaks is traditionally interpreted as an indication of the year’s agricultural conditions. The ritual therefore serves as a prayer for a good harvest and agricultural prosperity.
The Jingara Mochi ceremony is designated as an Intangible Folk Cultural Property of Nagareyama City. The tradition continues to be carefully passed down by the local community.
