Nachi Primeval Forest

Nachi Primeval Forest is an old-growth woodland containing more than 40 waterfalls, with the tallest dropping approximately 130 meters among towering trees and dense undergrowth. The terrain follows the natural water systems that shape the entire landscape.

The area received official status as a National Natural Monument of Japan in 1928 and was later included on the UNESCO World Heritage list. Recognition of its value led to broader protection of the landscape.

The forest holds spiritual meaning for visitors who come to experience the relationship between nature and sacred practice. You can see how people move through the space with reverence, particularly around the waterfalls where rituals have long taken place.

The terrain is wet and slippery year-round due to high humidity and frequent moisture, so sturdy footwear is essential for safe walking. Check conditions before visiting, especially during rainy seasons when trails become more challenging.

The forest supports specialized plant species adapted to its wet environment, including laurel forests and subtropical ferns found nowhere else in the region. This rare combination of moisture-loving vegetation makes the ecosystem distinct from surrounding forests.
