Geography and Panoramic Views
Mount Unpenji stands on the prefectural boundary between Tokushima and Kagawa, at the western end of the Sanuki Mountains. Near its summit, Unpenji Temple occupies a remarkable mountain setting surrounded by forests and open views. From elevated viewpoints, visitors can look across the landscapes of Shikoku and appreciate the mountain’s strategic position within the island.
The mountain is also associated with a dramatic episode in Japanese history. According to tradition, the Sengoku-period warlord Chosokabe Motochika climbed Mount Unpenji and surveyed the lands below, inspiring ambitions to bring all four provinces of Shikoku under his control. The story adds a historical dimension to the mountain’s impressive outlook.
Mountain Survey Markers
Mount Unpenji has several surveying triangulation points that may interest hikers and map enthusiasts. The second-order triangulation point named Unpenjisan, with an elevation of 910.7 meters, is located behind the western side of the NTT Docomo Unpenji communications facility near the summit. A fourth-order triangulation point called Janotani, at 916.2 meters, stands on the mountain’s western peak.
These markers were established to measure the surrounding terrain accurately. Although they are less prominent than the temple and observation facilities, they offer an additional point of interest for visitors curious about the mountain’s geography.
Historical Significance
Mount Unpenji has long been valued for its commanding position and spiritual associations. During the Sengoku period, when regional warlords competed for power, the mountain is said to have attracted Chosokabe Motochika because of its expansive views across Shikoku.
The historical account appears in the regional chronicle Zensanshi, which describes Motochika climbing the mountain, surveying the four provinces of Shikoku, and developing the ambition to bring them under his rule. Whether approached as history or legend, the story reflects the strategic importance that people have attributed to this high point for centuries.
How to Reach Mount Unpenji
Unpenji Ropeway
One of the most convenient ways to reach the mountain is the Unpenji Ropeway, which departs from Uchino-no in Onohara, Kannonji City, Kagawa Prefecture. Operated by Shikoku Cable, the ropeway opened on March 28, 1987, providing easy access to the mountain’s upper slopes and the temple area.
Road access is also available via Prefectural Route 8, which leads close to Unpenji Temple. However, reaching the upper area by car may require using a toll road, for which the stated fee for a standard passenger car is ¥500. Visitors planning to drive should check current road access and toll arrangements before setting out.
Unpenji Summit Park
Near the summit, Unpenji Summit Park offers visitors a place to enjoy the mountain scenery. One of its best-known attractions is the Sky Swing, installed in July 2020. Positioned to make the most of the elevated landscape, the swing creates the sensation of floating above Shikoku’s mountains and valleys.
On clear days, the views extend far across the surrounding countryside, making the park a popular destination for photographs and outdoor relaxation. The combination of open scenery and a distinctive swing makes it an appealing stop for travelers as well as families and casual visitors.
Bishamonten Observation Pavilion
The Bishamonten Observation Pavilion, associated with Unpenji Temple, is another highlight near the mountain’s highest point. From an elevation of approximately 927 meters, visitors can enjoy expansive views over Shikoku’s varied landscape. The pavilion also serves as a quiet place for reflection, bringing together the mountain’s religious significance and its natural beauty.
Snow Park Unpenji: A Former Ski Resort
In 2001, Shikoku Cable opened Snow Park Unpenji, which became known as Kagawa Prefecture’s only ski resort. The facility initially attracted approximately 26,000 visitors, offering a winter sports destination in a region better known for its milder climate.
In later years, warmer winters shortened the operating season, and visitor numbers fell to around 14,000 by the 2019–2020 season. The additional challenges created by the COVID-19 pandemic made continued operation difficult, and the resort closed in March 2020. Although it is no longer operating, its history remains part of the mountain’s more recent tourism development.
Hiking and Seasonal Nature
Mount Unpenji is a rewarding destination for hikers and nature enthusiasts. Its forested slopes and mountain trails offer opportunities to enjoy the landscape at a slower pace, with views opening up at points along the ascent. The mountain changes character with the seasons: spring brings mountain cherry blossoms and fresh green foliage, while autumn colors the surrounding forests in shades of red and gold.
A variety of plants grow around the upper slopes, making the area appealing to visitors interested in local flora as well as those seeking scenic walks. Conditions can vary with the weather and season, so hikers should prepare suitable clothing and footwear before setting out.
A Mountain of Faith, History, and Scenic Beauty
Mount Unpenji offers much more than a high viewpoint. Its association with the Shikoku 88-Temple Pilgrimage, its place in regional history, and its rich natural environment make it an important destination in western Shikoku. Visitors can explore the sacred surroundings of Unpenji Temple, take in the sweeping views from the summit area, or enjoy the mountain’s forests and seasonal colors on foot.
With access by ropeway and road, Mount Unpenji is suitable for both pilgrims and sightseeing travelers. The Sky Swing at Unpenji Summit Park and the views from the Bishamonten Observation Pavilion are particular highlights, offering memorable ways to experience the remarkable scenery from this mountain on the Tokushima–Kagawa border.
