Sumiyoshi-zukuri style architecture has no veranda (a narrow wooden passageway along the edge of a house facing the garden) or the sacred core pillar installed at the center of the main sanctuary of a shrine, and the inside is divided into a naijin (inner sanctuary of a shrine or temple) and a gejin (part of the main sanctuary outside the innermost sanctum of a shrine).
回縁と御心柱はなく、内部は内陣・外陣に区切られる。
