What hinoki means
Hinoki is the timber of the Japanese cypress (Chamaecyparis obtusa), an evergreen conifer, and it is the wood most often found in Japan's wooden cultural properties. The Agency for Cultural Affairs explains that the tree has long been treated as a first-rank building timber for shrines and temples because it lasts well and is easy to work. Japanese texts write the name three ways, as 檜, 桧 or ヒノキ, and all three appear in designation records and their commentaries.
In the context of cultural properties the word covers three distinct uses. The first is structural and finish timber: posts, beams, rafters and the joinery of interiors. Sugi (Japanese cedar) is also common for posts and for carved transoms, but the principal members of a shrine or temple building are more often hinoki. The second is sculpture. Hinoki is the standard wood for Buddhist statues carved as a single block or assembled from many blocks, the methods known as ichiboku-zukuri and yosegi-zukuri. The third is bark. Strips of bark peeled from standing trees are laid as roofing, and that roof type has its own entry as Hiwadabuki. This page deals with the wood; the bark belongs to the roofing entry.
How the word appears in records depends on the field. For buildings, the structure-and-form line of the national database records the roof shape and the roofing material, and it rarely names the species used for posts or beams. For sculpture the commentary almost always opens with the material and the construction. A seated Amida statue at Engyoji, for example, is introduced as hinoki assembled from joined blocks, and the text then describes how the blocks were split and fitted. Spelling varies between entries: another commentary, for a set of guardian kings at Kaijusenji, writes the same wood in katakana.
How to confirm hinoki in records and on site
For statues, the material given in the official commentary is the most reliable guide. Most carved images are covered with lacquer and gold leaf or with paint, so the grain cannot be read from outside. When a commentary names hinoki, the identification usually comes from conservation work or a survey that examined the interior. The statement applies to the body of the image; the pedestal and the halo may be of a different wood.
For buildings, a visitor looking at unpainted posts and boards cannot safely identify the species by eye. The dependable source is the report of a dismantling repair, which records the species of each member and whether it is original or a later replacement. Any statement that a hall stands on hinoki posts should rest on such a report or on material published by the owner.
Hinoki meets heritage policy most directly in the supply of repair materials. Since fiscal 2006 the Agency for Cultural Affairs has designated Furusato Bunkazai no Mori, forests and grasslands that serve as model sources and training grounds for the timber, bark, thatch and lacquer that repairs of historic buildings require. The published list of sites gives hinoki timber and hinoki bark as separate material types, a reminder that the same tree supplies both the posts of a building and its roof covering.
