Honden (Main Sanctuary)

The honden is the most sacred building within a Shinto shrine complex. It is here that the shintai (sacred object embodying the kami) is housed. Unlike the haiden (worship hall), the honden is generally not open to the public — ordinary worshippers pray from outside or from the haiden, and only priests enter the honden during specific rituals.

Architecturally, the honden tends to be smaller than one might expect for such an important structure. Some of the oldest surviving shrine architecture in Japan is found in honden buildings. The style varies greatly: the Shinmei-zukuri of Ise Jingu features a raised-floor structure with thatched roof and minimal ornamentation, while the Taisha-zukuri of Izumo Taisha is distinguished by its massive scale and central pillar. The Nagare-zukuri, with its characteristic asymmetrical gabled roof extending over the entrance, is the most common style nationwide.

Notably, a few important shrines such as Omiwa Jinja in Nara have no honden at all. At Omiwa, the mountain itself (Mt. Miwa) is considered the shintai, so there is no need for a building to house it — the haiden faces the mountain directly.
