Mount Rokko is a mountain range in southeastern Hyogo Prefecture, extending from the western outskirts of Kobe toward the north and east. Part of Setonaikai National Park, it is renowned for its natural beauty, hiking trails, panoramic viewpoints, and cultural attractions. The mountain range is also recognized as one of Japan’s New 100 Famous Mountains, the 300 Famous Japanese Mountains, and the 50 Famous Mountains of Hyogo Prefecture.
The name “Mount Rokko” generally refers to the entire Rokko mountain range, which consists of numerous peaks of varying heights. Its highest point is known as the Rokko-san Summit. The range stretches across Kobe, Ashiya, Nishinomiya, and Takarazuka, providing a striking natural backdrop to the surrounding cities and Osaka Bay.
The Rokko mountain range runs for more than 30 kilometers from southwest to northeast, beginning near the Akashi Strait and extending toward the area west of Takarazuka Station. Near the center of the range, the mountains change direction toward the east around Mount Maya. The range is relatively narrow from north to south, generally less than five kilometers wide, although the area around the highest summit reaches approximately 10 kilometers across.
The mountains are visible from much of Kobe and Osaka, making them a familiar landmark throughout the region. From various viewpoints on the northern side, visitors can also enjoy distant views of cities and surrounding landscapes when weather conditions are favorable.
The Rokko range forms a natural barrier between parts of Kobe and Nishinomiya. Numerous roads and railway lines cross the mountains, connecting the coastal urban areas with communities on the northern side. Along the southwestern edge of the range, the Sanyo Electric Railway Main Line, National Route 2, and the JR Kobe Line run parallel to the coastline.
Much of Kobe’s urban area developed on alluvial fans formed by rivers flowing down from Mount Rokko. The combination of the mountains, rivers, and sheltered coastline contributed to the development of Kobe Port as an important harbor.
The higher elevations of Mount Rokko are home to cultural facilities, hotels, and recreational attractions. Around the Rokko Sancho Station of the Rokko-Arima Ropeway and the Hoshi no Eki Station near the summit of Mount Maya, visitors will find a collection of facilities that give the area the atmosphere of a small mountain community.
Rokko Mountain School, operated by Kobe City, is located at one of the city’s highest elevations. In winter, its early use of heating has sometimes attracted attention in local news reports, reflecting the colder conditions found on the mountain compared with the city below.
The former main building of the old Rokko Mountain Hotel is known for its classic hotel architecture, while several historic Western-style villas remain in the area. Many of these buildings are privately owned and are not generally open to the public.
The stations of the Rokko Cable Railway are also notable for their early modern architecture, preserving a sense of the mountain’s history as a popular leisure destination.
Accommodation options in the wider mountain area have included facilities such as Hotel de Maya, formerly known as Maya Lodge, Rokko Sky Villa, Rokko YMCA, Kobe City Nature House, and Ocean Terrace Ajisai. The area has also been associated with historic establishments such as the Rokko Mountain Hotel and Maya Kanko Hotel. Today, private holiday homes, corporate retreats, and members-only villas are also characteristic of the mountain landscape.
The western part of the wider mountain system includes Mount Takatori, Mount Yokoo and the rugged trails known as the Suma Alps, as well as the Sumaura Sanjo Amusement Park. These mountains are sometimes distinguished from Mount Rokko itself, but they are geographically connected to the broader range and form part of the long-distance Rokko traverse route.
The bedrock of Mount Rokko consists mainly of granite formed deep underground approximately 100 million years ago, during the Cretaceous Period of the Mesozoic Era. Geological movements over a long period gradually raised this rock to its present elevation.
The southern slopes are particularly steep and rugged. Areas such as the Ashiya Rock Garden and Mount Kabuto illustrate the dramatic terrain created by the region’s geological history. The combination of exposed rock, forested slopes, and elevated ridges makes Mount Rokko a popular destination for hikers and nature enthusiasts.
Several faults run through the Rokko region in a northeast-to-southwest direction, playing an important role in the formation of the mountain range. The Nojima Fault, associated with the 1995 Great Hanshin-Awaji Earthquake, belongs to the broader fault system of this region.
In contrast to the steep southern slopes, parts of the summit area are relatively flat. These elevated surfaces, known as uplifted peneplains, provide suitable locations for golf courses, hotels, and other recreational facilities.
More than 20 river systems originate on Mount Rokko and flow south toward Osaka Bay. Other streams drain the northern slopes, supplying water to nearby urban areas and agricultural communities.
The mountain region also contains scenic bodies of water, including Hotaka Lake and Oike. These locations offer tranquil natural settings and are popular with visitors exploring the mountain’s hiking trails.
Hotaka Lake is a scenic mountain lake surrounded by greenery and hiking routes. It provides a peaceful setting for enjoying the natural landscape of Mount Rokko.
Oike is associated with the rugged landscape of Jigokudani, or Hell Valley, where dramatic terrain creates a striking contrast with the surrounding forest. The area appeals to visitors who enjoy exploring the mountain’s distinctive natural features.
Mount Rokko is an important source of natural water. Rainwater gradually seeps through the granite bedrock and surrounding geological layers, undergoing natural filtration before entering underground water systems. This process produces spring water containing a variety of minerals, and some sources can be accessed in areas near the city.
Water from Mount Rokko feeds the Nunobiki Stream, part of the upper reaches of the Ikuta River. The area is recognized for its high-quality water, and the Nunobiki Falls region has been selected as one of Japan’s 100 Remarkable Waters.
In 1900, the Nunobiki Gohonmatsu Dam was constructed to provide water for ships calling at Kobe Port. The water became known internationally as “Kobe Water” and earned a reputation among seafarers as water that would remain fresh even after crossing the equator.
In 1983, House Foods commercialized a bottled water product called “Rokko no Oishii Mizu,” meaning “Delicious Water from Rokko.” The product helped introduce the quality and reputation of Mount Rokko’s natural water to consumers throughout Japan.
Among the springs associated with Mount Rokko, Miyamizu, which emerges in Nishinomiya, is especially famous for its suitability for Japanese sake production. Its relatively high hardness and phosphorus content, combined with low iron levels, make it particularly valuable for brewing.
Miyamizu helped support the development of Nada Gogo, one of Japan’s most celebrated sake-producing areas. The region’s brewing tradition remains closely linked to the quality of its water and the natural environment of Mount Rokko.
Mount Rokko has long been associated with the name “Muko” or “Muko-san.” An early reference to “Muko no Minato” appears in the Nihon Shoki, one of Japan’s oldest historical chronicles, in its account of the first year of Empress Jingu’s regency. Several theories exist about the origin of the name, including the idea that the mountains were regarded as lying on the far side of the region when viewed from the old capital area.
The steep terrain of Mount Rokko made it suitable for mountain worship and religious ascetic practices from an early period. In 768, during the Jingo-keiun era, the Buddhist monk Waki no Kiyomaro is traditionally associated with the founding of Dairyuji Temple on the southern slopes of Mount Futatabi.
In the late Heian Period, Taira no Kiyomori established the temporary capital of Fukuhara-kyo, and timber and other construction materials were obtained from the Rokko mountains. The surrounding region later witnessed major conflicts, including the Battle of Ichi-no-Tani during the Genpei War, the Battle of Mount Maya in the Nanboku-cho Period, and the Battle of Hanakuma Castle during the Sengoku Period.
Repeated warfare and the heavy use of mountain resources contributed to the deterioration of the forests.
During the Edo Period, people living at the foot of the mountains relied on Mount Rokko for daily necessities. They built reservoirs, collected firewood, and cut trees for building materials. Over time, these activities greatly reduced the forest cover. By the early Meiji Period, many slopes had become so bare that Mount Rokko was described as a “bald mountain.”
During the Meiji Period, Western residents of Kobe’s foreign settlement began developing Mount Rokko as a place for recreation and relaxation. British resident Arthur Hesketh Groom played a central role in establishing the Kobe Golf Club, widely recognized as Japan’s first golf club and golf course. This development helped introduce Western-style leisure activities to the mountain.
A major flood in 1895 prompted the start of hillside planting and other erosion-control measures. Government-led reforestation projects continued over subsequent decades, gradually restoring the mountain’s forests.
Today, Mount Rokko is known for its green slopes, wooded trails, and rich natural environment. Its history demonstrates how conservation and disaster prevention helped transform a heavily degraded landscape into one of the region’s most important natural attractions.
Rokko Garden Terrace is one of the mountain’s best-known sightseeing destinations. Its observation areas offer sweeping views of Kobe, Osaka Bay, and the surrounding landscape. At night, the city lights create a spectacular panorama that attracts visitors throughout the year.
Rokko Mountain Ranch is a popular destination for families and animal lovers. Visitors can encounter sheep, cattle, and other animals in a spacious natural setting. Dairy products made using milk from the ranch are also popular, allowing visitors to enjoy some of the mountain’s local agricultural produce.

On clear days, the higher viewpoints of Mount Rokko offer far-reaching views in every direction. To the west, visitors may see the Akashi Kaikyo Bridge, Awaji Island, and the Harima Plain. Views to the south can include Mount Kongo, the Osaka Bay coastline, Kansai International Airport, Kobe Airport, and Tomogashima in the Kii Channel.
Looking east, the landscape extends toward Mount Ikoma, the Osaka Plain, Osaka International Airport, the Yodo River, and the skyscrapers of central Osaka. Under exceptionally clear conditions, distant mountain ranges in Shikoku, the Chugoku region, Tamba, and the Kii Peninsula may also be visible.
Mount Rokko is celebrated for its spectacular night scenery and is often associated with Japan’s three major night views. The expression “million-dollar night view” is also linked to Kobe and Mount Rokko. One popular explanation traces the phrase to the estimated monthly electricity cost of the city’s lights in the 1950s, which was said to amount to one million dollars.
Today, the panorama is often promoted as Kobe’s “ten-million-dollar night view.” From the mountain, the illuminated city, harbor, and coastline form an impressive scene, making Mount Rokko one of the region’s most popular destinations after sunset.
Kikuseidai is a famous viewpoint near the summit of Mount Maya. Its spacious observation area offers sweeping views across Kobe and Osaka Bay, particularly after dark. The name evokes the image of scooping stars from the sky, an apt description of the glittering city lights below.
Ryoundai is located west of the Rokko-san Summit and provides open views toward the southeast. Nearby attractions include Rokko Garden Terrace, Rokko Country House, and the summit station of the Rokko-Arima Ropeway.
