This was originally the main entrance to the mountain. At the time Koyasan was founded, just below where Daimon now stands there was a torii (the traditional red Japanese@entrance gate to a Shinto shrine or sacred space). The area was then known as Tsuzure-dani. The present Daimon is a reconstruction dating from 1705. Two enormous wooden statues of the guardian deities Kongo-rikishi flanking the entrance were carved by the sculptors Koi and Uncho during the Edo period. As part of the 1150th memorial celebration of Kobodaishi's passing held in 1981, the entire gate was dismantled and overhauled, a task completed in 1986 after five years' work. The gate measures 21.4 meters wide, 7.7 meters deep, and 25.1 meters tall. [Designated as a nationally recognized Important Cultural Property]
