Definition

There is no universally agreed definition of Shinto. However, the authors Joseph Cali and John Dougill stated that if there was "one single, broad definition of Shinto" that could be put forward, it would be that "Shinto is a belief in kami ", the supernatural entities at the centre of the religion. The Japanologist Helen Hardacre stated that "Shinto encompasses doctrines, institutions, ritual, and communal life based on kami worship", while the scholar of religion Inoue Nobutaka observed the term "Shinto" was "often used" in "reference to kami worship and related theologies, rituals and practices". Various scholars have referred to practitioners of Shinto as Shintoists, although this term has no direct translation in the Japanese language.

Scholars have debated at what point in history it is legitimate to start talking about Shinto as a specific phenomenon. The scholar of religion Ninian Smart suggested that one could "speak of the kami religion of Japan, which lived symbiotically with organized Buddhism, and only later was institutionalized as Shinto." While several institutions and practices now associated with Shinto existed in Japan by the 8th century, various scholars have argued that Shinto as a distinct religion was essentially "invented" during the 19th century, in Japan's Meiji era. The scholar of religion Brian Bocking stressed that, especially when dealing with periods before the Meiji era, the term Shinto should "be approached with caution". Inoue Nobutaka stated that "Shinto cannot be considered as a single religious system that existed from the ancient to the modern period", while the historian Kuroda Toshio noted that "before modern times Shinto did not exist as an independent religion".
