The 'O-sugi' cedar trees along the path are estimated to be over 800 years old.
The path served as a gateway where pilgrims would change into white traditional 'byakue' robes before approaching the shrine.
The cobblestones are purposefully uneven to signify the struggle and spiritual purification of the pilgrimage journey.
The route was historically part of the Imperial pilgrimage path used by Retired Emperors during the 10th to 12th centuries.
Daimon-zaka translates to 'Great Gate Slope,' referring to a grand entrance gate that once stood at the base but no longer exists.
The Daimon-zaka slope is a 600-meter-long cobblestone approach to the Kumano Nachi Taisha shrine, lined with centuries-old cedar and camphor trees. This path is the most well-preserved section of the Kumano Kodo pilgrimage network. The stones were originally laid in the Heian period to provide a stable route for imperial pilgrims. The trail features a 220-meter vertical ascent through a dense, moss-covered forest. It culminates near the Kumano Nachi Taisha and the three-tiered Nachi Falls, the tallest single-drop waterfall in Japan. The area is part of the UNESCO World Heritage site 'Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.'
The Meoto Sugi (Husband and Wife Cedars) located halfway up the slope, which frame the path perfectly.
Wear footwear with excellent grip, as the centuries-old stones become extremely slippery when damp.
Use the available wooden walking sticks found at the start of the path to assist with the steep incline.
Bring a small towel and water, as the forest humidity remains high even in cooler months.
Attempting the climb in smooth-soled shoes or sandals, which poses a significant slipping hazard on the moss-covered slopes.
Maintain a quiet tone to respect the spiritual nature of the pilgrimage route; do not remove stones or disturb the moss.
