A Winding Gorge Along the Naka River
Located at the northern foot of Mount Kodoyama, Hoki Gorge extends for approximately 2 kilometers. The Naka River meanders through the valley, creating a picturesque landscape that can be admired from National Route 195, which runs alongside the gorge.
The scenery changes with the seasons. In spring, white azaleas brighten the surrounding slopes. Summer brings deep green foliage and a refreshing riverside atmosphere, while autumn transforms the valley with colorful leaves. Each season offers a different perspective on this quiet mountain landscape.
Natural Spring Water Beside the Road
Several spring-water spots can be found beside the road through Hoki Gorge. Known collectively as the Hoki Gorge spring water, these sources attract travelers who stop during their drive to collect the clear water.
The springs are particularly appealing during the warmer months, when the cool mountain surroundings offer a welcome break from the summer heat. If you plan to collect water, follow any local guidance and check whether the source is currently suitable for drinking.
The Meaning Behind the Name Hoki Gorge
The name “Hoki” is thought to derive from the word “hoki,” referring to a steep, unstable cliff or slope. The name reflects the rugged terrain characteristic of the gorge and the surrounding mountain valleys.
The Naka River: A Lifeline of Tokushima
The Naka River is a major river in Tokushima Prefecture, flowing for approximately 125 kilometers and forming the longest river located entirely within the prefecture. Its headwaters lie in the Tsurugi mountain range near Jirogyu. From there, the river flows south through mountainous terrain, passing scenic areas such as Konose Gorge before eventually reaching the Kii Channel.
The river was historically associated with the name Nagakawa, linked to the ancient regional name Naga-no-Kuni. References to “Naga” and “Naga-no-Kuni” appear in the Nihon Shoki, one of Japan’s oldest historical chronicles. The name Naka River became established around the Heian period and continues to be used today.
The Naka River plays an important role in the region’s natural environment and water resources. Its clear waters, winding valleys, and mountain scenery support a variety of outdoor activities and contribute to the appeal of the surrounding countryside.
Dams and Scenic Attractions Along the River
Several dams have been constructed along the Naka River to support regional water management. Major examples include Nagayasuguchi Dam, one of Tokushima Prefecture’s largest dams, and Kawaguchi Dam. A proposed Hosokawauchi Dam was ultimately canceled following local opposition, leaving the upper river area without that planned development.
The river basin is also home to a variety of natural and cultural attractions. Highlights include Uo-o Falls in Anan, Tairyūji Temple—associated with the Buddhist practice of Kūkai—and the Tairyūji Ropeway, as well as Hyochu Kannon, Konose Gorge, and the forest roads and mountain scenery around Mount Tsurugi.
How to Get to Hoki Gorge
By car: Hoki Gorge is approximately two hours by car from JR Tokushima Station. National Route 195 runs alongside the gorge, making it possible to enjoy views of the river and surrounding mountains during the drive.
By public transportation: From JR Tokushima Station, take the Tokushima Bus Nyūya Line toward Kawaguchi and get off at Kawaguchi Bus Office, the terminus. Transfer to a Tokushima Bus Nanbu service and get off at Kुमonmyō, then walk for approximately five minutes to reach the gorge. Bus schedules and connections should be checked before departure, as services in this mountainous area may be limited.
Enjoy the Quiet Beauty of Rural Shikoku
Hoki Gorge offers a relaxing way to experience Tokushima’s mountain scenery. Whether you stop to admire the winding river, enjoy the seasonal colors, or take a break beside the spring-water spots, the gorge rewards visitors with a quieter side of Japan beyond its major cities and well-known tourist centers.
Combine a visit with a drive through the Naka River valley to discover more of the region’s waterfalls, mountain landscapes, and riverside attractions. With careful travel planning, Hoki Gorge makes a memorable stop on a nature-focused journey through Tokushima Prefecture.
