During the Edo period, it is estimated that one out of ten Japanese conducted an "Okage Mairi" pilgrimage to the shrine. Accordingly, pilgrimage to the shrine flourished in both commercial and religious frequency. According to historical documents, 3.62 million people visited the shrine in 50 days in 1625, and 1.18 million people visited the shrine in three days in 1829 when the grand festival held every 20 years was held. Because the shrine is considered sanctuary, no security checkpoints were conducted, as it was considered sacrilege by the faithful. The two main shrines of Ise are joined by a pilgrimage road that passes through the old entertainment district of Furuichi.
