Rafting on the Yoshino River
The Yoshino River, known as one of Japan’s top rafting spots and affectionately nicknamed “Shikoku Saburo” (“Saburo” being a traditional name for a third son), features thrilling rapids and once hosted the World Rafting Championships.
While the whitewater offers plenty of excitement, the stunning river valleys provide a calming contrast. Some courses pass directly beneath Sameura Dam, and thanks to gentler currents, they’re perfect for families with children or even dogs.
Courses are available for participants as young as elementary school age. Please check with each operator about age requirements and experience levels when booking.

Sameura Dam
A must-see when visiting Tosa Reihoku, the Sameura Dam is a massive structure that plays a vital role in protecting Shikoku.
As the largest-capacity multipurpose dam in western Japan, it has been the core of water resource management for the Yoshino River system since operations began in April 1975.
The dam helps prevent flooding, regulates river flow, supplies water, and generates electricity—earning it the nickname “Shikoku’s water barrel” for its essential support of daily life and industry.
The lake’s surface reflects stunning seasonal scenery, and the area is popular for bass fishing, water sports, and more.
Local events such as the Yamabiko Carnival (December) and the Sameura no Sato Lakeside Trail Race (November) also take place nearby.

Tanada
In the Tosa Reihoku area, there are many terraced fields called tanada. They are rare in Japan, and people come from around the world to see the tanada.
From the tanada observation deck in Oishi, Motoyama, the home of a specially cultivated type of rice twice selected as the best rice in Japan called Tosa Tenku no Sato, you can take in a panoramic view of terraced fields that have remained nearly unchanged since the Yayoi period 2,300 years ago.

Climbing
Located along the Shikoku Mountains, the Tosa Reihoku area is home to many captivating mountains.
You can choose a climbing trail suitable for your own level.
Please make sure you wear hiking shoes and bring along the necessary equipment.
Elevation: 1,469.4m above sea level
The trail for this mountain is laid with wooden walkways, and it takes around 90 minutes to climb the mountain. You can enjoy akebono-tsutsuji (Rhododendron pentaphyllum) and shakunage (Rhododendron subg. Hymenanthes) flowers in full bloom here in spring. There is also a grove of dessicated white tree trunks known as "hakkotsurin" (literally, "white-bone forest") near the summit of the mountain.
Elevation: 1,399.6m above sea level
The climbing trail for this mountain features many highlights, including Ryuo-no-taki, one of Japan's top 100 waterfalls and one of Tosa's 40 famous water bodies; Miei-do, a wooden hall with a close connection to Kobo Daishi; and the Okunoin (inner shrine) of Jofuku Temple. You can explore this area conveniently if you stay at Star Lodge Kajigamori.
Elevation: 1,506.2m above sea level
This trail starts from the Inamura Dam and passes through an artificial forest, and it remains relatively gentle as it goes up the mountain. You will reach the summit after passing through a tunnel with shakunage (Rhododendron subg. Hymenanthes) flowers. Stunning views await you at the summit.
Elevation: 1,587m above sea level
Even elementary school students can easily climb this trail, which has few ups and downs. The huge primeval beech forest you will encounter along the way is absolutely breathtaking. Many native alpine plants grow in the area, which you can enjoy through the four seasons.
Elevation: 1,279.3m above sea level
This mountain allows you to experience the history of the Shirataki mining district. You can reach the start of the trail by car, and although the trail has some steep slopes at the start, you can make your way to the summit in no time. This trail is suitable for beginners as well.
