What shinbutsu-shūgō is
Shinbutsu-shūgō names the fusion of kami worship with Buddhism that took hold from the Nara period and shaped religious practice for over a thousand years, until a government order separated the two in the early Meiji period.
Precincts still carry the traces. The bell tower at Kasuga Shrine in Oita Prefecture, built in 1830, is described as standing south of the worship hall across the approach from the sacred dance hall, a single-bay tower on a flared base with a cut-stone footing, Irimoya-zukuri with Hongawarabuki, and the entry says it conveys the syncretic character of a precinct in the early modern period. That a bell tower stands inside a shrine is itself the evidence.
The reverse arrangement also survives. Ishiyamadera in Shiga Prefecture is described as having a shrine hall of 1602, richly carved and coloured, which with its worship hall built at the same time preserves the arrangement of a guardian shrine within a temple precinct.
Sumiyoshi Taisha in Osaka, a National Treasure, is described with the note that the ground between its main halls and a subsidiary shrine was the precinct of an attached temple until the early Meiji period.
What separation moved
The Meiji order divided precincts that had been single. The main hall of Mio Shrine in Shiga Prefecture, built in 1426, is described as having been the guardian shrine of a temple, standing in the south-west of its precinct, and as having moved outside that precinct at the separation to become an independent shrine.
Buildings were moved, halls were removed, names were changed. The present appearance of a precinct rarely shows what stood there before.
When writing, note the context in which a record uses the term. Praising a precinct as evidence of the older arrangement and explaining a relocation are different statements.
The term names neither an architectural manner nor a style. It belongs to a separate question from Wayō or Zenshūyō: who was enshrined in a building and how it was used.
