An Ancient Tradition of Nature Worship
At Hiro Shrine, a sacred area known as a himorogi is established approximately 200 meters in front of the waterfall. This serves as the principal place of worship. From here, visitors can stand quietly before the magnificent waterfall and offer their prayers.
Rather than relying on an elaborate religious building, the shrine allows the natural landscape to serve as the focus of worship. This distinctive tradition provides a glimpse into the ancient Japanese belief that mountains, waterfalls, forests, and other elements of nature can possess a sacred presence.
For international visitors, Hiro Shrine offers a particularly meaningful opportunity to experience an aspect of Japanese spirituality that predates many of the architectural traditions commonly associated with Shinto shrines.
Nachi Falls and the Blessing of Longevity
Nachi Falls has traditionally been associated with health and longevity. According to local belief, the fine spray rising from the waterfall carries sacred power, and coming into contact with it is said to bring blessings for a long and healthy life.
Standing near the waterfall, visitors can feel the cool mist on their skin while listening to the powerful sound of falling water. The experience can create a strong impression of purification and renewal, both physically and spiritually.
A UNESCO World Heritage Sacred Site
The grounds of Hiro Shrine and Nachi Falls form part of the UNESCO World Heritage property known as the “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.”
The wider Kumano region has been an important center of religious practice for centuries. Pilgrims, Buddhist monks, and mountain ascetics traveled through its forests and mountains in search of spiritual purification and enlightenment.
The close relationship between the natural environment and religious traditions is one of the most important characteristics of the area. The sacred mountains, forests, waterfalls, and pilgrimage routes together represent an important part of Japan’s spiritual and cultural heritage.
Nachi Falls: One of Japan’s Most Famous Waterfalls
A Spectacular 133-Meter Waterfall
Nachi Falls is located along the Nachi River in Nachikatsuura Town. The waterfall plunges dramatically over a vertical cliff of quartz porphyry, creating one of the most impressive natural landscapes in Wakayama Prefecture.
The waterfall is approximately 13 meters wide, while the vertical drop from the top to the basin below reaches approximately 133 meters. As a single uninterrupted waterfall, it is one of the tallest and most spectacular in Japan.
Its immense scale and beauty have attracted visitors for centuries. The waterfall is also so prominent that its presence can be appreciated from distant areas around the Kumano region.
One of Japan’s Three Great Waterfalls
Nachi Falls is traditionally counted among the Three Great Waterfalls of Japan, together with Kegon Falls in Tochigi Prefecture and Fukuroda Falls in Ibaraki Prefecture.
Although its total vertical drop is not the greatest among all Japanese waterfalls, its uninterrupted 133-meter descent gives it an especially powerful and impressive appearance.
The Mysterious “Three-Stream Waterfall”
One of the most distinctive features of Nachi Falls is the way the water appears to divide into three streams as it passes over natural cracks in the rock at the top of the waterfall.
For this reason, the waterfall is sometimes known as the “Three-Stream Waterfall.” The division of the water creates a graceful and mysterious appearance that distinguishes Nachi Falls from many other waterfalls.
It is also commonly called “Nachi no Otaki,” or the Great Nachi Waterfall, reflecting its importance as the most famous waterfall of Nachisan.
Shinto Traditions and Annual Festivals
The Sacred Rope Renewal Ceremony
A large shimenawa, a sacred rope used in Shinto to mark a sacred space, hangs near the top of the waterfall. It clearly indicates that Nachi Falls is regarded as a divine and sacred place.
The shimenawa is replaced during important annual ceremonies, including around New Year and before the major festival known as the Nachi Fire Festival, or Nachi Ogi Matsuri. The renewal ceremony symbolizes the continued protection and purification of the sacred waterfall.
The Nachi Fire Festival
Held annually on July 14, the Nachi Fire Festival is one of the most spectacular traditional events associated with Hiro Shrine.
During the ceremony, enormous flaming torches are carried through the sacred area. The combination of fire, traditional rituals, mountains, and the powerful waterfall creates a dramatic scene that attracts both worshippers and visitors.
Other ceremonies related to the sacred rope are also held throughout the year, including ceremonies in July and December. These traditions demonstrate how the spiritual connection between the shrine and waterfall continues to be carefully preserved.
Highlights Around the Shrine
Nachi Falls: A National Place of Scenic Beauty
Nachi Falls is designated as a National Place of Scenic Beauty in Japan, recognizing both its exceptional natural scenery and its cultural importance.
The waterfall viewing area provides visitors with an impressive perspective of the falling water. The sound, mist, surrounding forests, and enormous scale of the waterfall combine to create a memorable experience.
The Waterfall Worship Stage and Goma Hall
The Waterfall Worship Stage provides a special place from which visitors can worship while experiencing the waterfall at close range. It is an ideal location for appreciating the connection between nature and religious practice.
The nearby Goma Hall is used for Buddhist-style fire rituals and prayers. Its presence also reflects the historical relationship between Shinto and Buddhism in the Kumano region.
The Shrine Office
The shrine office provides information for visitors and offers goshuin, traditional temple and shrine stamps collected by many travelers as a record of their visit.
Receiving a goshuin can be a meaningful way to commemorate a visit while learning more about Japan’s traditional pilgrimage culture.
A Sacred Place Where Nature and Faith Become One
Hiro Shrine and Nachi Falls represent one of the most remarkable examples of the relationship between nature and spirituality in Japan. Instead of worshipping a statue or a building, visitors stand before an immense waterfall that has itself been revered as a divine presence for centuries.
This ancient form of nature worship gives the site a unique atmosphere that is difficult to experience elsewhere. The sound of the falling water, the mist in the air, the surrounding forests, and the sacred traditions all contribute to a profound sense of peace.
As part of the UNESCO World Heritage property “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range,” the area is also an important destination for understanding Japan’s religious and cultural heritage.
For international travelers interested in Japanese spirituality, Shinto traditions, World Heritage sites, dramatic natural scenery, and ancient pilgrimage culture, Hiro Shrine and Nachi Falls are highly recommended destinations.
A visit here is more than a sightseeing experience. It is an opportunity to encounter a living tradition in which the power and beauty of nature have been respected as sacred for more than a thousand years.
