Daibutsuyō

The style was introduced by priest Chōgen, who in 1180 directed the reconstruction of Tōdai-ji, which had been destroyed during the Genpei war.[2] Chōgen had just come back from the last of his three travels to China and therefore chose as a basis for the work Song Dynasty architecture. He was supported in his innovative work by first shōgun Minamoto no Yoritomo.

Of his work at the temple only three structures remain, the already mentioned Nandaimon, which remains the best Daibutsuyō example, the Kaizandō and the Hokkedō.[2] The gate's most characteristic features are the six-tier bracket groups (tokyō) projecting directly out of the columns and connected to each other by ties as long as the facade.[2] During the Edo period the temple's Main Hall, the Daibutsuden, was also rebuilt in the style, to which it would give its name.

Chōgen built other buildings in this style near and around Nara, of which the Amida-dō at Jōdo-ji in Ono is a good extant example.[2]

The style declined quickly after its creator's death, probably because it did not agree with Japanese tastes. Structural elements are treated as design elements, and the building's deliberate roughness is supposed to be part of its beauty, but the concept was probably too alien to Chōgen's contemporaries, and was rejected.[5]

Nandaimon (detail). Note the exposed tōrihijiki

The Daibutsuyō style was short-lived but innovative, and many of the ideas it introduced were adopted by other styles as well. In particular, during the Muromachi period the traditional Wayō style was so heavily influenced that the mix of the two is sometimes called Shin-wayō.

• Thick woodwork and imposing general look
• Use of penetrating tie beams

During the Heian period temples were built using only non-penetrating tie beams (nageshi (長押)) made to fit around columns and pillars and nailed. The daibutsuyō style, first, and the zenshūyō style, later, replaced them with penetrating tie-beams (nuki (貫)), which actually pierced the column, and were therefore much more effective against earthquakes.[6][7] The nageshi was however retained as a purely decorative element.[8]

• Thick, visible structural elements with decorative function

As already mentioned, many structural elements are left uncovered and have a decorative function. For example, the roof's supporting members are not covered by a ceiling and are therefore fully visible from within the temple.[7] The Nandaimon's stabilizing bracket ties (tōrihijiki (通り肘木))[9] which run the entire width of the gate are also fully visible (see photo on the right). (Other styles hide them, at least partially.) Structural elements are much thicker than in Zen buildings.[7]

• Sashihijiki

The sashihijiki (挿肘木) is a bracket arm inserted directly into a pillar instead of resting onto a supporting block on top of a pillar, as was normal in the preceding wayō style (see photo on the right). At Tōdai-ji, both the Nandaimon and the Daibutsuden have six sashihijiki one on top of the other (mutesaki tokyō). (On the subject, see also the article Tokyō).

• Ōgidaruki

Another detail unique to this style are the ōgidaruki (扇垂木, lit. fan rafters).[7] The rafters supporting each roof corner spread from a single point, in a fan-like pattern.

• Kibana

The tips of each protruding beam ends in a nose-like structure called kibana (木鼻, lit. wooden nose).[7]
