A form of elementary, perhaps prototypical, shrine or shintai comprising an unpolluted space marked out by stakes and shimenawa or surrounded by evergreens, with a sacred sakaki tree at the centre as the 'seat' of the kami. Nowadays the sakaki branches may be arranged on an eight-legged table (hassokuan) hung with shide to represent the shintai. There are numerous suggested etymologies for himorogi; the term may refer equally to the 'tree' or to the marked space.
