Tanzan Shrine (談山神社)

Tanzan Shrine stands on the wooded slopes of Mount Tonomine in Nara Prefecture, surrounded by maple trees that turn the hillside crimson each November. It is the only shrine in Japan with a 13-story wooden pagoda, and the site where the political conspiracy that created modern Japan was planned in 645 CE. The shrine’s name means “談山” — “Talking Mountain” — because it was here, beneath these same trees, that Nakatomi no Kamatari and Prince Naka no Ōe met in secret to overthrow the Soga clan and establish the imperial system that would last fourteen centuries.

The shrine was founded in 678 CE by Kamatari’s son, Jōe, who brought his father’s remains from their original burial site to this mountain. Kamatari had died thirteen years after the successful Taika Reforms, the sweeping political restructuring that followed the Soga overthrow. Initially established as Myōraku-ji, a Buddhist temple, the complex maintained dual Shinto-Buddhist identity until the Meiji separation of 1868, when it became purely Shinto and took its current name. The 13-story pagoda was first built in 678 and rebuilt in 1532 after fire — it remains the only surviving wooden 13-story pagoda in Japan, and the oldest structure of its kind. The shrine was designated an Important Cultural Property, with the pagoda itself holding National Treasure status.

Fujiwara no Kamatari (614-669 CE) is the primary deity enshrined here — not a mythological kami but a deified historical figure. Born as Nakatomi no Kamatari, he orchestrated the Isshi Incident that ended Soga dominance over the imperial court, then served as the chief architect of the Taika Reforms that centralized imperial power and established the ritsuryō legal system modeled on Tang China. The emperor granted him the new surname Fujiwara just before his death, and his descendants became the most powerful aristocratic family in Japanese history, dominating the court for four centuries. He is venerated as a kami of political wisdom, loyalty to the throne, and the founding spirit of the Japanese state structure. His divine domain encompasses governance, strategic thinking, and the proper relationship between sovereign and subject.

The central legend that gives the shrine its name occurred in the spring of 645 CE, when nineteen-year-old Prince Naka no Ōe — later Emperor Tenji — climbed this mountain to play kemari (courtly football) with the young courtier Nakatomi no Kamatari. During the game, Kamatari deliberately kicked the ball to make the prince’s shoe fly off, then knelt to return it — a gesture of respect that opened their conversation. The two withdrew to a secluded spot on the mountain, where they spoke for hours about the Soga clan’s stranglehold on imperial authority. Over subsequent secret meetings on this mountain, they planned the assassination of Soga no Iruka and the overthrow of his father Soga no Emishi. On the twelfth day of the sixth month, 645 CE, they executed their plan during a court ceremony: the prince himself killed Iruka with a sword, blood spattering the throne room, while Emishi committed suicide as his mansion burned. The mountain where they conspired became sacred ground, and the maple trees that witnessed their plotting became the shrine’s enduring symbol.

The 13-story pagoda rises 17 meters through the forest canopy, its vermilion-lacquered structure creating a striking contrast against the surrounding greenery and autumn maples. The main worship hall (honden) sits on a stone foundation overlooking the valley, connected to the pagoda by a covered corridor. The shrine complex includes the Kondō (main hall), which houses a seated wooden statue of Kamatari from the Kamakura period, and the Kenbutsuden museum displaying historical artifacts including scrolls depicting the Isshi Incident. Stone lanterns line the approach path, and a small kemari court commemorates the legendary football game. The architecture reflects Momoyama period aesthetics, with elaborate carvings and bright vermilion paint that intensifies during the autumn color season. The entire complex is integrated into the forested mountainside, with buildings positioned to frame views of the surrounding 3,000 maple trees.

• Kemari Matsuri (April 29 & November 3) — Courtly football is performed in historical costume on the shrine grounds, reenacting the legendary game between Kamatari and Prince Naka no Ōe. Eight players in Heian-period aristocratic dress kick a deerskin ball, attempting to keep it aloft using only their feet.
• Momiji Matsuri (mid-November) — The autumn maple festival celebrates the peak color season with traditional music, dance performances, and illuminations of the pagoda and surrounding forest. The shrine becomes one of Nara’s premier autumn viewing destinations.
• Tanzan-sai (November 17) — The annual festival honoring Kamatari’s legacy, featuring Shinto rituals, court music (gagaku), and processions.

Mid-November during peak autumn color, when the 3,000 maple trees create layers of crimson, orange, and gold surrounding the vermilion pagoda. The shrine offers extended evening hours during this period with illumination. Visit on a weekday morning before 10 AM to experience the forest atmosphere with fewer crowds, or attend the November 3 Kemari Matsuri to see both the autumn colors and the historical reenactment. Late April during fresh green season offers a quieter alternative with the spring Kemari performance, and cherry blossoms frame the pagoda’s lower levels.
