Let us widen the lens to the region around Hie Shrine, because Hida's climate shaped everything built here. This is the story of the area, not of one building, and it explains a lot about what you see. Hida receives a great deal of snow, and it was a production center for timber. In Takayama's surviving Edo period government compound, the Takayama Jin'ya, the roofs are covered in several different styles, with names such as noshi-buki, kokera-buki and ishiokinagakure-buki. Every one of them uses wooden shingles. Compared with clay roof tiles, which were easily worn down by ice and snow, wood was more readily available and held up better to the weather. So if you notice timber, shingles and steep, practical roof shapes as you walk around Takayama, you are looking at centuries of local adaptation to mountains, snow and forest.
