The History of Okinoshima
We do not have extensive records of Japan’s early history. The oldest written chronicles, the Kojiki and the Nihon shoki, were compiled in the early eighth century. These records mention that the Munakata family performed rituals for the Three Female Deities of Munakata at sites on Okinoshima, at Mt. Mitake on Oshima, and at Takamiya Saijo on the grounds of Hetsu-miya. These rituals took place from the fourth century when rituals started on Okinoshima, to the ninth century, when most rituals were transferred to the mainland.
When these rituals were first being performed, Buddhism had arrived in China from India, but had not yet been introduced in Japan. Toward the end of the period of these rituals, Ise Jingu in Mie Prefecture and Izumo Taisha in Shimane Prefecture, Japan’s oldest and most revered Shinto shrines were built, and worship had mostly moved from outdoor spaces to more permanent structures built for ritual purposes.
