Nitta Shrine (Satsumasendai City) (新田神社 (薩摩川内市))

Nitta Shrine stands on a low hill in Satsumasendai, surrounded by the graves of twenty-one generations of the Shimazu clan — the feudal lords who ruled Satsuma Province for seven hundred years. The shrine’s position is not incidental: it marks the tomb of Ninigi-no-Mikoto, the grandson of the sun goddess Amaterasu, who descended from heaven to rule the earth. This is the only shrine in Japan where the deity’s actual burial mound serves as the main worship object. You do not enter a building to pray; you stand before a forested hill and address the earth itself.

Nitta Shrine’s origins reach back to the mythological age described in the Kojiki and Nihon Shoki. According to these chronicles, Ninigi-no-Mikoto descended to the peak of Mount Takachiho in Kyushu, bringing with him the three imperial regalia. He ruled the land and eventually died at the age of 580 years old in the palace of Takaya. His tomb was established at this site, later named Kanden-san (可愛山陵). The shrine itself was formally constructed during the early Heian period, around 774 CE, to serve the burial mound. The Shimazu clan, recognizing the political and spiritual significance of housing the progenitor of the imperial line, made Nitta Shrine their family shrine and established their own cemetery on the surrounding hillside, effectively tying their legitimacy to the founding myth of Japan.

Ninigi-no-Mikoto (瓊瓊杵尊) is the central deity, the divine grandson sent by Amaterasu to bring order to the earthly realm. He is the ancestor of the imperial family and the deity of nation-founding, agriculture, and governance. His descent from the heavens — known as the Tenson Kōrin — is the mythological event that legitimizes the imperial line’s divine right to rule. Within the shrine grounds, the burial mound itself is considered his sacred body, a concept called goshintai. The shrine also enshrines Konohanasakuya-hime, Ninigi’s wife, a goddess of volcanoes and delicate life, and Hikohohodemi-no-Mikoto, their son, who later became the grandfather of Emperor Jimmu, Japan’s legendary first emperor.

The shrine’s primary legend concerns the circumstances of Ninigi’s death and burial. After descending to Kyushu, Ninigi married Konohanasakuya-hime, the daughter of the mountain deity Ohoyamatsumi. She became pregnant on their wedding night, and Ninigi, suspicious, doubted the children were his. To prove her fidelity, she entered a doorless hut and set it on fire, vowing that if the children were divine, they would survive. Three sons emerged unharmed from the flames. The eldest, Honosuseri, became a fisherman, while the second, Hikohohodemi, became a hunter. Ninigi spent his final years in a palace at Takaya, where he eventually died. His retainers carried his body to this hill and constructed a burial mound. The Shimazu lords later identified this mound and made it the spiritual center of their power. To disturb the earth of the tomb is still considered a grave taboo — the forest covering the mound has never been cleared, and no excavation has ever been permitted.

The shrine’s main structure is a modest wooden hall built in the Ryōbu Shinto style, integrating Buddhist and Shinto elements. The true sacred object is not inside — it is the forested mound behind the worship hall, a hill approximately fifteen meters high and sixty meters in diameter. The mound is encircled by a stone wall and accessible only to priests on rare ritual occasions. The surrounding grounds contain the Shimazu family cemetery, with stone markers and monuments spanning from the 12th century to the Meiji era, creating a landscape where myth and history occupy the same terrain. A stone torii at the base of the approach path marks the boundary between the town below and the sacred hillside. The shrine grounds also contain several subsidiary shrines, including one dedicated to the Shimazu ancestors.

• Reitaisai (October 20-21) — The annual grand festival honoring Ninigi, featuring ritual offerings of rice, sake, and seafood placed before the burial mound, mikoshi processions through Satsumasendai, and traditional Satsuma hayato dance performances by local children dressed in ancient warrior costumes.
• Hatsumode (January 1-3) — New Year visits draw thousands of worshippers who pray for national prosperity and family continuity, reflecting Ninigi’s role as the divine ancestor of the nation.
• Niiname-sai (November 23) — The harvest thanksgiving festival, during which the first rice of the season is offered to Ninigi in gratitude, echoing his original mission to bring rice cultivation to Japan.

Late autumn, particularly mid-November, when the surrounding cedar and camphor trees take on deeper tones and the air is cool and still. The Shimazu cemetery becomes especially atmospheric during this season, when fallen leaves cover the stone pathways and the sense of deep time is palpable. Early morning visits offer solitude and the chance to experience the forest mound in quiet. Avoid the October festival dates if you prefer contemplation over crowds, though the hayato dances are worth witnessing if you’re interested in Satsuma warrior culture.
