In Tokushima Prefecture on the island of Shikoku, the grandeur of nature unfolds in dramatic contrast between sea and mountains. Witness the awe-inspiring Naruto Whirlpools—among the largest in the world—and venture into the remote beauty of Iya Valley, counted among Japan’s “Three Great Hidden Regions.”
This three-day journey takes you far from the rhythms of everyday life and deep into a world shaped by time, water, and wilderness. It’s a rare chance to reconnect with nature—and with yourself—amid landscapes both powerful and serene.
Day 1: From Osaka or Kobe to Tokushima – Experiencing the Power of the Naruto Whirlpools
Begin your journey by heading to Naruto City in Tokushima Prefecture, crossing via Awaji Island. Easily accessible by car or express bus, it takes about 2 to 3 hours from Osaka.
Your first destination is the legendary Naruto Whirlpools, a spectacular natural phenomenon caused by tidal shifts and the unique topography of the Naruto Strait beneath the Ōnaruto Bridge. Hop aboard a sightseeing boat to feel the thrill of these massive whirlpools up close—an exhilarating experience that feels as though you’re being swept into the raw power of nature. For the best views, aim to visit during high or low tide, and be sure to check the tidal schedule in advance.
Afterward, head to Uzu no Michi, a glass-floored walkway built into the structure of the Ōnaruto Bridge. From here, you can look down at the churning waters from above—a spine-tingling perspective that adds another layer of awe. End the day with a stay in the Naruto Onsen area. Unwind with local seafood cuisine and soak in the quiet beauty of the Seto Inland Sea as night falls.
Day 2: From Tokushima City to Iya Valley – Into the Heart of the Hidden Mountains
After breakfast, set out for the remote Iya Valley in western Tokushima—a place often called one of Japan’s last hidden regions. The drive takes about 2.5 hours from Tokushima City, following the Yoshino River deep into a landscape of dramatic mountains and winding gorges. As you ascend into this secluded terrain, the scenery gradually shifts into something wild and otherworldly.
The highlight of the region is the Iya no Kazurabashi, a 45-meter-long suspension bridge woven from mountain vines. Suspended 14 meters above the gorge, every step across this swaying bridge stirs a primal reverence for nature—and a real sense of adventure. The view and sense of accomplishment at the other end are unforgettable.
In the afternoon, visit the Iya Valley Viewpoint and the whimsical Statue of the Peeing Boy, daringly perched on a cliff’s edge. From here, take in the staggering V-shaped valley and steep ravines stretching far below—a scene that leaves even the most seasoned traveler speechless. Stay overnight in a local ryokan or hot spring inn in Iya Onsen or Oku-Iya. Soak in natural, free-flowing thermal waters under the stars, embraced by the silence of the valley. It’s a night of rare stillness and awe, deep in the mountains of Shikoku.
Day 3: Oboke and Koboke – Concluding with the Beauty of the Gorge
On your final day, take time to visit Oboke and Koboke, dramatic river gorges near the Iya region. Carved by centuries of erosion, these striking rock formations symbolize the raw power of the Shikoku Mountains. A ride on a sightseeing boat offers a peaceful, up-close encounter with the gorge’s jagged cliffs and the crystal-clear flow of the Yoshino River—a tranquil farewell to nature’s grandeur.
Along the way, enjoy the tastes of Tokushima’s rural cuisine. Try Soba-gome Zosui, a warming buckwheat and rice porridge, or Dekomawashi, skewers of tofu, konnyaku, and vegetables grilled in miso sauce—a comforting end to your mountain adventure.
Return to Tokushima City for your departure via airport or expressway. If time allows, stop by a renowned Tokushima ramen shop and enjoy one last local delicacy before bidding farewell to this unforgettable journey through Shikoku’s wild and hidden heart.
