Chigi (Forked Roof Finials)
X-shaped wooden beams projecting from the roof ridge of a shrine building
Chigi are the distinctive V-shaped or X-shaped wooden projections that extend upward from the ridge of a shrine's roof. They are one of the most recognizable architectural features of traditional Shinto shrine buildings and distinguish them visually from Buddhist temple roofs.
A popular tradition holds that the way the chigi are cut indicates the gender of the enshrined kami: if the tips are cut vertically (sogi-chigi), the kami is male; if cut horizontally (uchi-sogi), the kami is female. While this rule generally holds for Ise Jingu — where the inner shrine (Naiku) for the female Amaterasu has horizontal chigi and the outer shrine (Geku) for the male Toyouke has vertical chigi — it is not consistently applied across all shrines.
Chigi likely originated as a purely structural element: the crossed ends of the roof beams that projected beyond the ridgepole in ancient raised-floor buildings. Over time, they became a decorative and symbolic feature. Today they evoke the deep antiquity of shrine architecture and are strongly associated with the Japanese aesthetic of rustic simplicity.
