By the end of the Yayoi period, large earthen tombs called kofun were built and these two became sites of worship. Kofun construction came to an abrupt end at around the time Buddhism appeared and family temples and shrines became important centers of ancestor and deity worship.
Here I offer another section from the Introduction to "Shinto Shrines" that highlights some of the most common shrine building styles. This excerpt is in two parts.
Building types (part 1)
While there are a number of building types, they fall into two categories. The first is a generic type not necessarily associated with any single shrine. The second is usually named after the shrine where the style originated. The second category may extend to no more than a handful of shrines in the same geographic location.
Irimoya-zukuri: This is a general description of a building style that uses a hip-and-gable roof. The simple gable roof (called kirizuma-zukuri) forms an inverted V shape seen from the end. The surface may be flat, slightly concave, or convex. The hip-and-gable adds a lower, pent roof to the gable side, forming an A shape seen from the end. The full hip roof style (yosemune-zukuri) has four sloping rooflines, meeting at the top at a very short ridgepole. It creates a more or less symmetrical profile and a roof that looks very large compared with the building. The full hip style is more common in temple construction. The hip-and-gable style is common for shrines.
