With regards to the dimensions of the shrines, I studied the relation between the dimensions of the frontage of the shinto shrine, including the main shrine and that of the attached buildings. The dimensions of the buildings were basically determined as the length between the pillar centers. However, other measurement methods, such as the “outside measurement” (oze) and “inside measurement” (daki) were also used. Focusing on this aspect, I clarified that the relation between the frontage dimensions of the main and attached buildings can be expressed in simple ratios based on whole numbers.
