Kasuga-zukuri

あ Kasuga-zukuri (春日造) is a traditional Shinto shrine architectural style which takes its name from Kasuga Taisha's honden.

[1][2] In Kasuga Taisha's case, the honden is just 1.9 m x 2.6 m.[3] Supporting structures are painted vermilion, while the plank walls are white.

[4] If a diagonal rafter (a sumigi (隅木)) is added to support the portico, the style is called sumigi-iri kasugazukuri (隅木入春日造).

This shows that, for example, both the nagare-zukuri Kamo Shrine and Kasuga Taisha used to be dedicated to a mountain cult, and that they had to be moved to follow the movements of the kami.

[1] The styles also both have a veranda in front of the main entrance, a detail which makes it likely they both evolved from a simple gabled roof.
