Hachiman-zukuri


The hachiman-zukuri is a traditional Japanese architectural style used at Hachiman shrines in which two parallel structures with gabled roofs are interconnected on the non-gabled side, forming one building which, when seen from the side, gives the impression of two. The front structure is called gaiden, the rear one naiden, and together they form the honden. The honden itself is completely surrounded by a cloister-like covered corridor called kairō'. Access is made possible by a gate called rōmon.
It has a hirairi or hirairi-zukuri structure, that is, the building has its main entrance on the side which runs parallel to the roof's ridge. There are entrances also at the center of the gabled sides. In general, the rear structure is 3x2 ken, while the front one is 3x1.
The space between the two structures is one ken wide and forms a room called ai-no-ma. The actual width and height of this room vary with the shrine.
Extant examples are Usa Shrine and Iwashimizu Hachiman-gū. This style, of which only five Edo period examples survive, may be of Buddhist origin, since some Buddhist buildings show the same division. For example, Tōdai-ji's hokke-dō is divided in two sections laid out front and back. Structural details also show a strong relationship with the Heian period style called shinden-zukuri used in aristocratic residences. Another possible origin of this style may have been early palaces, known to have had parallel ridges on the roof.
