Introduction

Standing majestically in the Ushirodateyama Range of the Northern Alps, Mt. Shiroumadake continues to captivate countless mountaineers with its silvery ridgeline at 2,932 meters and its reputation as one of Japan’s premier alpine plant treasuries. For the 2026 season, even more comfortable climbing conditions have been prepared, including maintenance of the Daisekkei (Great Snow Valley) route and improvements to mountain hut facilities. This article provides an easy-to-understand introduction for first-time visitors, covering everything from the mountain’s overview to its history and recommended spots.

To convey the full charm of Mt. Shiroumadake, this article thoroughly examines the mountain from three perspectives: an “Overview” covering the mountain’s basic profile, the “History” of people’s relationship with the mountain, and “Recommended Spots” that you absolutely must not miss when visiting.

Overview of Mt. Shiroumadake

Mt. Shiroumadake (Shiroumadake) is a mountain standing at 2,932 meters, straddling Hakuba Village in Kitaazumi District, Nagano Prefecture, and Kurobe City, Toyama Prefecture. It is the highest peak of the Ushirodateyama Range in the northern part of the Hida Mountains (Northern Alps), and its majestic mountain form and rich natural environment have made it beloved by many mountaineers. It has been designated as one of Japan’s 100 Famous Mountains, the New 100 Famous Flower Mountains, and the 100 Famous Flower Mountains.

– Origin of the Name

The original Japanese name is “Shiroumadake.” This derives from the horse-shaped snow pattern (“Shirouma”) that appears on the mountain slope as snow melts in early spring. The villagers at the foot of the mountain used this snow pattern as a signal to begin their agricultural work. Over time, the kanji for “Shirouma” (pack horse) came to be written as “Hakuba” (white horse), and the pronunciation “Hakuba” gradually became widespread.

In particular, when a railway opened at the foot of Mt. Shiroumadake in 1906, the station was named “Hakuba,” and as the ski resort became internationally known as “HAKUBA,” the pronunciation “Hakubadake” became established. Currently, the Geospatial Information Authority of Japan officially registers the name as “Shiroumadake,” but it is also commonly called “Hakubadake.” The name of Hakuba Village also derives from this mountain.

– Geography and Geology

As the main peak of the Ushirodateyama Range, Mt. Shiroumadake forms a magnificent ridgeline extending to Mt. Korenge to the north and Mt. Shakushidake and Mt. Shiroumayaridake to the south. The summit area is relatively gentle and broad, offering excellent panoramic views.

Geologically, the eastern side of the mountain is composed of easily weathered serpentinite, which causes large-scale collapses and contributes to the formation of the “Shirouma Daisekkei” (Great Snow Valley), one of Japan’s three great snow valleys. The western side, on the other hand, is made of hard granite, giving the mountain its characteristic asymmetrical profile. Multiple cirques (glacially carved depressions) can be found around Mt. Shiroumadake.

– Rich Natural Environment

Mt. Shiroumadake is renowned as a treasure trove of alpine plants, having been selected as one of Japan’s “100 Famous Flower Mountains.” It is particularly notable for the many endemic and rare species that have adapted to the unique serpentinite soil.

• Representative Alpine Plants:
  • Lagotis glauca (Uruppuso): A rare species found only on Mt. Shiroumadake, Mt. Yatsugatake, and Rebun Island in Hokkaido.
  • Pulsatilla nipponica (Tsukumogusa): The “Queen of Alpine Plants,” found only in a few mountain areas in Japan.
  • Additionally, large colonies of Anemone narcissiflora (Hakusan-ichige), Ranunculus acris (Miyama-kinpouge), Dicentra peregrina (Komakusa), and Trollius japonicus (Shinano-kinbai) delight climbers along the way.
• Wildlife:
  • The area is also famous as a habitat for the Japanese ptarmigan (raicho), designated as a Special Natural Monument of Japan. With luck, you may spot them in the dwarf pine zones.
  • Other wildlife including Japanese stoats (okojo) and Japanese serows (kamoshika) also inhabit the area.
    

– Mountaineering

Due to its popularity and fame, Mt. Shiroumadake has well-maintained trails and mountain huts, making it known as a gateway mountain for exploring the Northern Alps. However, its high altitude and rapidly changing weather conditions require proper equipment and planning.

• Major Climbing Routes:
  • Shirouma Daisekkei Route: The most popular and shortest route to the summit. Since you climb through snow valleys even in summer, snow equipment such as crampons is essential. Extra caution against rockfall is also necessary.
  • Tsugaike Panorama Way Route: Starting from Tsugaike Nature Garden, you take a gondola and ropeway to reach approximately 1,900 meters elevation. The ridgeline walk via Hakuba-Oike and Mt. Korenge offers abundant alpine plants and excellent views.
  • Shirouma Yari Onsen Route: A challenging traverse route entering from Sarukura, with an overnight stay at Shirouma Yari Onsen Hut, a natural hot spring at one of Japan’s highest elevations.
• Mountain Huts:
  • Hakuba Sanso: A historic mountain hut opened in 1906. With a capacity of approximately 800 guests, it boasts one of the largest scales in Japan. It has well-equipped restaurant and shop facilities.
  • Shiroumadake Summit Lodge: A mountain hut approximately 15 minutes from Hakuba Sanso, with an adjacent campsite.
  • Other huts including Hakuba Oike Sanso and Shirouma Yari Onsen Hut are scattered along the various routes.

History of Mt. Shiroumadake

The history of Mt. Shiroumadake has undergone a great transformation — from a mountain deeply tied to the daily lives of the people at its foot, to a stage that pioneered modern mountaineering, and finally to a world-class mountain resort. Here we introduce this grand journey through five major milestones.

　1. [A Mountain of Faith and Livelihood] Snow Patterns and Agricultural History

Long before the advent of modern mountaineering, Mt. Shiroumadake served as an indispensable “calendar” and object of worship for the people living at its base. Particularly important was the “snow pattern” (yukigata) that appeared on the mountain slope during spring snowmelt. The locals called the horse-shaped pattern on the eastern slope the “Shirouma” (pack horse) and used it as a signal to begin rice paddy preparation.

This name “Shirouma,” deeply connected to daily life, eventually came to be written with the characters for “white horse” (Hakuba), becoming the origin of the mountain’s current name. Mt. Shiroumadake was not merely beautiful — it was a mountain deeply intertwined with people’s livelihoods.

　2. [Dawn of Modern Mountaineering] Opening Doors to the World and Laying the Foundation

In the Meiji era, Mt. Shiroumadake became the central stage for pioneering Japan’s mountaineering history. The greatest catalyst was the 1894 ascent by Walter Weston, a British missionary known as the “Father of Modern Japanese Mountaineering.” Through his writings, Weston introduced the magnificent scenery and beautiful alpine plants of Mt. Shiroumadake to the world, bringing the name “Japanese Alps” to international recognition. Inspired by this, travel writer Kojima Usui and others summited in 1902, igniting a passion for mountaineering among Japan’s intellectuals and youth.

In response to the growing number of climbers, Hakuba Sanso — one of Japan’s earliest commercial mountain huts — was built just below the summit in 1906 through the efforts of local guide Matsuzawa Teiitsu. These three major developments of the Meiji era — international exposure, domestic popularity, and infrastructure development — combined to establish Mt. Shiroumadake’s enduring status as a sacred site of modern mountaineering.

　3. [Symbol of the Region] The Birth of “Hakuba Village” Named After the Mountain

As mountaineering developed, Mt. Shiroumadake became a source of regional pride and the very identity of its people. The symbolic event was the birth of “Hakuba Village” in 1958. When the two villages of Kamishiro and Hokushiro merged at the time, the name of the great mountain shared by both was chosen as the new village’s name.

It is rare for a mountain’s name to become the official administrative name, which speaks to how Mt. Shiroumadake has been a spiritual pillar and a beloved presence for the people of this region.

　4. [Protecting Nature] National Park Designation and Environmental Conservation

As mountaineering became more accessible, concerns grew about the environmental impact of increasing visitors. In this context, in 1956, the Mt. Shiroumadake area was designated as a Special Protection Zone of the Chubu-Sangaku National Park, recognizing its outstanding natural scenery, rare alpine plant communities such as Lagotis glauca, and precious ecosystems including ptarmigan habitats.

This was an important turning point that officially positioned the value of Mt. Shiroumadake not merely as a climbing destination but as “nature that must be protected” — a national treasure. Since this designation, various efforts to pass on this beautiful nature to future generations have continued to this day, including trail maintenance, vegetation protection, and ptarmigan conservation activities.

　5. [Leap to International Resort] The Nagano Olympics and “HAKUBA” Goes Global

Following the Showa-era ski boom, the foot of Mt. Shiroumadake developed into one of Japan’s premier ski resorts, but it was the 1998 Nagano Winter Olympics that brought the name to global fame. Hakuba Village served as the venue for alpine skiing and other events, drawing athletes and spectators from around the world. This established “HAKUBA” as an international brand, transforming the area from a summer mountaineering destination into a year-round mountain resort visited by skiers and snowboarders from around the world seeking premium powder snow.

With its historic mountain culture fused with world-class hospitality, Mt. Shiroumadake continues to attract visitors to this day.

The appeal of Mt. Shiroumadake is not limited to the sense of achievement from standing atop its 2,932-meter summit. Along the trails and throughout the surrounding wilderness, there are numerous breathtaking spots that move every visitor. Here is a carefully curated selection of must-see spots when visiting the Mt. Shiroumadake area.

The summit of Mt. Shiroumadake is an absolute must. Standing on the spacious and open summit, all your fatigue melts away with the overwhelming sense of achievement and the breathtaking panorama. To the north, you can see Mt. Korenge and the Sea of Japan; to the east, Mt. Myoko and the Togakushi Range; to the south, the Shirouma Three Peaks (Mt. Shakushidake, Mt. Shiroumayaridake) stretching to Mt. Kashimayarigatake; and to the west, Mt. Tsurugi and the Tateyama Range — a sweeping view of the Northern Alps’ greatest peaks.

On clear days, you may even glimpse Mt. Fuji in the distance. The first-class triangulation point at the summit has become a commemorative photo spot for many climbers. The sunrise and sunset vistas are particularly spectacular — a supreme luxury that can only be experienced by staying at a mountain hut.

　2. Shirouma Daisekkei — An Extraordinary Experience Walking One of Japan’s Three Great Snow Valleys

The “Shirouma Daisekkei” is synonymous with Mt. Shiroumadake. One of Japan’s three great snow valleys alongside the Fuji Oosawa on Mt. Fuji and the Harinoki Snow Valley of Mt. Harinokidake, it boasts a magnificent scale of approximately 3.5 km in length with an elevation gain of about 600 meters. Even in midsummer, cool breezes blow through, and the experience of walking through this silver world surrounded by towering rock walls is truly extraordinary.

Crampons with at least six prongs are essential for walking on the snow, and special caution is needed in autumn when crevasses deepen. Yet the dramatic scenery continues to captivate climbers. In summer, alpine plants bloom profusely around “Nebukappira” at the upper end of the snow valley, adding delicate colors to the harsh natural environment.

*Note: There is a constant danger of rockfall on the snow valley, so wearing a helmet is strongly recommended. On days with poor weather, visibility drops significantly, so reckless behavior should be avoided.

　3. Hakuba Oike and Hakuba Oike Sanso — A Mystical Lake Floating in the Sky

Located along the route from Tsugaike Nature Garden to Mt. Shiroumadake, “Hakuba Oike” sits at an elevation of 2,379 meters. One of the Northern Alps’ largest volcanic dammed lakes, its mesmerizingly clear blue surface creates a stunning contrast with the surrounding green dwarf pines and rugged mountain slopes.

The red-roofed “Hakuba Oike Sanso” by the lakeside adds color to the landscape, creating a picture-perfect scene. From late July to August, flower fields of Geum pentapetalum (Chinguruma) and Primula cuneifolia (Hakusan-kozakura) spread around the lake, creating a scene truly worthy of being called a paradise in the sky.

　4. Tsugaike Nature Garden — An Alpine Plant Paradise Accessible to All

While serving as one of the gateways to Mt. Shiroumadake, this location is itself a premier sightseeing spot in the Hakuba area. Easily accessible by gondola and ropeway to approximately 1,900 meters elevation, it features one of Japan’s finest highland marshlands. With boardwalks totaling about 5.5 km in length, even those with limited physical stamina or families with children can casually enjoy the magnificent alpine nature and breathtaking views of the Shirouma Three Peaks.

Starting with vast colonies of Asian skunk cabbage (Mizubasho) in late June, followed by cotton grass (Watasuge) and day lilies (Nikko Kisuge) in summer, and spectacular grass autumn colors in fall, the garden reveals completely different expressions with each season — its greatest charm.

　5. Hakuba Sanso — Japan’s Largest Mountain Hut Worth Staying At

“Hakuba Sanso,” standing just below the summit at 2,832 meters, is not merely an accommodation facility — it is a destination worth visiting in its own right. Boasting one of Japan’s largest capacities at approximately 800 guests and a long history dating back to its 1906 founding, it features accommodation, a panoramic restaurant called “Sky Plaza Hakuba,” a shop with original goods, and even a cafe — remarkably well-equipped for a mountaintop location.

The greatest allure is the sunrise from the summit and the star-filled sky that seems within arm’s reach — experiences reserved exclusively for overnight guests. A night at this hut, where history and comfort coexist, will become an unforgettable memory of your Mt. Shiroumadake climb.

[Bonus] Happo-ike Pond — The Stunning Mirror Reflection of the Shirouma Three Peaks

While not on the climbing route of Mt. Shiroumadake itself, Happo-ike is a must-visit when in the Hakuba area. Located at 2,060 meters on the Happo-one Ridge, it is relatively easily accessible by gondola and lifts. The true highlight of this spot comes on clear, windless days when the pond surface becomes as still as a mirror, perfectly reflecting the majestic forms of the Shirouma Three Peaks (Mt. Shiroumadake, Mt. Shakushidake, Mt. Shiroumayaridake).

This mystical beauty has graced the covers of many tourism posters and photo collections, making it truly the quintessential landscape of Hakuba.
