What Are Ōboke and Koboke? (Ōboke Gorge Travel Guide)

Ōboke and Koboke are gorges in Miyoshi City, Tokushima Prefecture, carved over many years by the Yoshino River cutting through the Shikoku Mountains. They are among Shikoku’s most famous scenic spots.

The name “Boke/Hoke” is an old word meaning cliffs or steep slopes, and is said to refer to a “large cliff” and a “small cliff” (it is also popularly explained as “dangerous whether you take big steps or small steps”).

Stretching for about 8 km, the gorge features crystalline schist rock faces and unusual formations sculpted by the clear Yoshino River. Its grand landscape is designated as a National Place of Scenic Beauty and Natural Monument.

Another major draw is the wide range of nature-based activities, including rafting and sightseeing cruises down the river.

Frequently Asked Questions

A. Oboke and Koboke are an approximately 8-kilometer gorge carved by the fast-flowing Yoshino River over about 200 million years. The area includes Oboke Gorge, a nationally designated Natural Monument, and is known for its rock faces that look like marble carvings. It is a scenic destination where you can feel the scale of the landscape from both trains and sightseeing boats.
A. JR Oboke Station is the main gateway, and the boarding point for the Oboke Gorge sightseeing boat is about 25 minutes on foot or around 5 minutes by car. If you are driving, it takes about 35 minutes from Ikawa-Ikeda IC via Route 32. If you are traveling by train, staying around the station is convenient, while drivers can easily combine the area with the sightseeing boat or a trip toward Iya.
A. The Oboke Gorge sightseeing boat costs 1,500 yen for adults and 750 yen for children. Operating hours are 9:00 to 17:00, with the last departure at 16:30. The ride takes about 30 minutes, so it is easy to fit into your schedule, and one of its biggest draws is that you can see the heart of the gorge without the physical effort of rafting.
A. No reservation is needed for individual visitors. Sailings may be canceled in strong winds or high water, so it is reassuring to check operating conditions before you go if the weather looks uncertain. During holiday periods, people tend to gather around the ticket area, so it is easier to plan your time if you secure a departure slot soon after arriving.
A. If you only take the sightseeing boat, around 30 minutes is enough, while allowing 1.5 to 2.5 hours is a good guide if you also want to enjoy viewpoints and the roadside station. Many people also continue on to Iya Kazurabashi Bridge, so it works well to plan half a day for the gorge itself, or a full day if you want to include the Iya area too.
A. Yes. Around Oboke and Koboke, there are rafting courses for beginners through advanced visitors, including half-day and full-day options. Most experiences are guided, so they are easy to join even if it is your first time. Keeping your change of clothes and towel in separate waterproof bags also makes moving around much easier after you get wet.
A. Visits increase during the fresh green season, autumn foliage season, and holiday periods, especially during the day, so weekday mornings or visiting outside normal lunch hours are usually more comfortable. People often gather between sightseeing boat departures, so it is efficient to check the next sailing time first and then walk around the area.
A. Oboke-kyo Mannaka, near the sightseeing boat boarding area, is a convenient base with meals, souvenirs, and lodging in one place. It is also easy to combine with Iya soba or freshwater fish dishes, and adding Roadside Station Oboke helps turn the trip into more than just a quick stop for the scenery.
