What shiraki-zukuri is
Shiraki-zukuri finishes the timber without paint or lacquer, leaving the wood bare, so that the grain and the quality of the material make the appearance.
Shrine architecture uses it. The main hall of Tomobayashi Shrine in Osaka Prefecture, built in 1940, is described as a three-bay hall in the Kasuga form with a gabled front canopy, double rows of closely spaced Taruki, billets on the main ridge and finials outside the ridge boards, its steps enclosed where it joins the offering hall, and is called a large and formal modern hall built in bare Taiwanese cypress.
Naming the timber matters. With nothing covering it, the grade of the wood determines the standing of the building. The subsidiary hall in the same precinct is described as built this way with heavy members and Munamochi-bashira standing upright without lean.
Showing the material is the design. The shrine at the Asahiya pharmacy in Saitama Prefecture, built in 1912, is described as of bare timber showing its grain well, with finely shaped mouldings on the beam above the openings.
Set against painted work
Precincts sometimes contrast the two. The gate at Jikoji in Niigata Prefecture, built in 1785, is described as having a frame based on Zenshūyō with three-block brackets, Kaerumata between them and a gable of paired curved beams and struts, its timber painted red, which the entry notes sets it apart in a precinct otherwise finished in bare wood.
A red gate in a precinct of bare timber stands out, and whether a building is painted states its place among the others.
Buddhist architecture leans the other way. The Konjikido at Chusonji, lacquered black and covered in Kinpaku inside and out, is the opposite pole. Shrines take bare timber as the norm while halls build up coatings for splendour.
On site, look at the surface of the timber. Visible grain with knots and variations of colour showing indicates bare wood; an even colour covering everything indicates a finish.
