Geology and the Formation of Mount Myogi
Mount Myogi is composed mainly of dacite lava, tuff, and conglomerate. The mountain is believed to have formed through volcanic activity associated with the Motegi Caldera approximately several million years ago.
The volcanic activity produced large masses of lava and volcanic rock. Over time, the softer surrounding sedimentary layers were gradually eroded, leaving the harder rock formations exposed.
This long process of erosion created the steep cliffs and unusual rock towers that characterize Mount Myogi today. The resulting landscape is considered one of Japan’s most distinctive examples of unusual mountain scenery.
Mount Myogi is also included in the traditional Gunma karuta card game, Joshu Karuta. The card for the syllable “Mo” features the phrase “Mount Myogi shining against the autumn leaves.”
Omote-Myogi and Ura-Myogi – Two Distinct Sides of the Mountain
Mount Myogi is broadly divided into Omote-Myogi, or Front Myogi, on the southeastern side, and Ura-Myogi, or Back Myogi, to the northwest.
Separated by the Nakaki River, the two areas feature different arrangements of dramatic cliffs and rock peaks stretching from southwest to northeast.
The Rock Towers of Omote-Myogi
Omote-Myogi includes Mount Hakuun, Mount Kinkei, and Mount Kondo. Mount Soma, adjacent to Mount Hakuun, reaches 1,104 meters and is the highest point of the area.
Vertical rock walls rise like enormous screens, while narrow pinnacles project dramatically into the sky. These formations are often described as rock towers because of their distinctive shapes.
Notable formations include Odaiko Rock and Hitto Rock. Their appearance changes dramatically depending on the viewing angle, allowing visitors to appreciate the remarkable forms created by natural erosion.
The Rugged Peaks of Ura-Myogi
Ura-Myogi is centered around Mount Yakyu, which reaches 1,162.1 meters. Sharp peaks such as Chosunosakazura and Eboshiiwa rise from the rugged mountain landscape.
The terrain here is generally more severe than in Omote-Myogi, and many routes are intended for experienced mountaineers. Visitors should carefully assess trail conditions and their own experience before attempting the more difficult routes.
The Popular Stone Gate Trail
One of the most accessible and popular ways to experience Mount Myogi is the Ishimon Meguri, or Stone Gate Trail, in Omote-Myogi.
The route passes through four natural stone gates, known as the First, Second, Third, and Fourth Stone Gates. The trail is relatively short, and some sections can be enjoyed with ordinary walking shoes.
However, the area around the Second Stone Gate includes sections equipped with chains. Hikers need to proceed carefully, particularly when the rocks are wet or weather conditions are poor. An alternative route is available for visitors who wish to avoid the chain sections.
The View from the Fourth Stone Gate
One of the highlights is the spectacular view known as Higurashi-no-kei, seen from beside the Fourth Stone Gate.
The name suggests a view so beautiful that visitors could spend an entire day watching it without becoming tired of the scenery. The combination of enormous rock formations, forested slopes, and distant mountain views captures the distinctive beauty of Mount Myogi.
A Landscape of Striking Rock Formations
The area around Nakano-dake is particularly famous for its unusual rock formations. Along the Stone Gate Trail, visitors encounter the First through Fourth Stone Gates as well as formations with memorable names such as Rousoku-iwa (“Candle Rock”), Odaiko-iwa (“Great Drum Rock”), Hitto-iwa, Yurugi-iwa, and Komuso-iwa.
The trail begins and ends near Nakanodake Shrine and attracts many visitors who want to experience Mount Myogi’s unusual mountain scenery without undertaking a full mountain traverse.
A Sacred Mountain with a Long History of Worship
Mount Myogi has been regarded as a sacred mountain since ancient times and has played an important role in Japanese mountain worship.
On the eastern slopes stands the solemn Myogi Shrine, which enshrines Mount Hakuun as its sacred mountain. On the Mount Kondo side stands Nakanodake Shrine.
Myogi Shrine is traditionally said to have been founded in 537, during the reign of Emperor Senka. During the Edo period, the shrine attracted many worshippers who believed in its spiritual protection against fires and lightning.
Today, the shrines and surrounding mountain landscape continue to provide an opportunity to experience the close relationship between Japanese religious traditions and the natural environment.
One of the Birthplaces of Modern Mountaineering in Japan
Mount Myogi also has an important place in the history of modern mountaineering in Japan.
In 1912, British mountaineer Walter Weston is said to have introduced Japanese climbers to rope techniques at Mount Myogi. The mountain’s steep cliffs and exposed rock faces provided valuable opportunities for developing climbing skills.
Because of this history, Mount Myogi is often associated with the development of modern mountaineering culture in Japan.
A Challenging Mountain Traverse for Experienced Hikers
The summit traverse from Mount Hakuun to Mount Kondo is a demanding route that takes approximately 7 hours and 20 minutes.
The trail includes numerous chain sections, exposed rock ridges, and steep terrain. It is intended for experienced hikers and climbers with appropriate equipment and route-finding skills.
Along the way are landmarks such as Dai-no-ji, Oku-no-in, Mount Soma, and Taka Modoshi. On clear days, hikers can enjoy sweeping views toward Mount Asama and across the Kanto Plain.
Because falls and other accidents have occurred on the more difficult routes, careful preparation is essential. Hikers should check current conditions, submit an entry form where required, and plan the route according to weather, daylight hours, and their own experience.
A More Relaxed Alternative – The Chukan-michi Trail
For visitors who prefer a less demanding mountain experience, the Chukan-michi trail connecting Myogi Shrine and Nakanodake Shrine offers a way to enjoy the natural scenery along the mountainside.
The route forms part of the Kanto Fureai Trail network and provides opportunities to experience the forests, rock formations, and mountain views without attempting the most difficult summit routes.
Mount Myogi as a Tourist Destination
Mount Myogi can be visited throughout much of the year, and improved roads make the mountain convenient to explore by car.
Prefectural Route 196 is also known as the Myogi Autumn Leaves Line. During autumn, the road becomes a popular scenic drive surrounded by brilliantly colored foliage.
The Matsuida-Myogi Interchange on the Joshin-Etsu Expressway provides convenient access, making Mount Myogi an excellent stop on a wider sightseeing trip through western Gunma.
Roadside Station Myogi
Near the First Torii Gate is Roadside Station Myogi, which includes a tourist information center and a local products center.
Visitors can purchase locally grown agricultural products and regional specialties while also gathering information about hiking routes, sightseeing spots, and seasonal conditions around Mount Myogi.
Mount Myogi in Japanese Art, Literature, and Popular Culture
The distinctive silhouette of Mount Myogi has inspired Japanese artists and writers for generations.
Painter Hogai Kano sketched Mount Myogi while preparing his celebrated work Mother and Child Kannon. Writer Tatsuo Hori also described the mountain in his essay Etranger.
Mount Myogi has appeared in popular culture as well, including the film series Otoko wa Tsurai yo and the manga and anime series Initial D.
Its distinctive rocky peaks are also celebrated in the Hokuriku section of the Railway Song, which compares the mountain’s jagged silhouette to a spear, sword, or saw.
The Origin of the Name “Myogi”
One traditional explanation says that the name Myogi originated with Nagachika-kyo, a court noble who served Emperor Go-Daigo.
He is said to have described the magnificent mountain as “Meimei Gigi,” expressing its brilliant and imposing appearance. The characters and pronunciation later changed, eventually giving rise to the name “Myogi.”
The name is fitting for a mountain whose rugged peaks can appear to glow dramatically in sunlight.
A Spectacular Mountain in Every Season
Mount Myogi offers a different landscape throughout the year. Mountain cherry blossoms appear in spring, followed by fresh green foliage in early summer.
Autumn is particularly spectacular, when vivid red, orange, and golden leaves contrast with the dark rock formations. In winter, the clear, crisp air makes the sharply defined peaks especially striking.
Although Mount Myogi is famous among hikers and climbers, visitors do not need to tackle its most difficult trails to appreciate its beauty. Scenic drives, short walks, viewpoints, shrines, and the Stone Gate Trail all provide ways to experience the mountain.
With its extraordinary rock formations, deep religious history, and dramatic seasonal scenery, Mount Myogi is one of Gunma’s most distinctive natural landmarks. Whether explored on foot, by car, or from the grounds of its historic shrines, the mountain offers an unforgettable glimpse of the unusual landscapes that have made Japan famous for its varied natural beauty.
