Oboke & Koboke: Japan’s Untamed Natural Wonder

#cityplaybook Tucked into the rugged mountains of Tokushima Prefecture, the twin gorges of Oboke and Koboke are among Japan’s most thrilling and scenic escapes. Formed by the powerful flow of the Yoshino River cutting through solid rock over millions of years, these dramatic ravines offer visitors a rare glimpse into Japan’s wilder side. Adventurers can dive into whitewater rafting, tackling Class III–IV rapids in one of the country's top rafting spots. Prefer a calmer pace? Hop on the Oboke Sightseeing Boat to glide through crystal-clear waters flanked by steep cliffs and lush forest. In autumn, the foliage turns fiery red and gold, casting stunning reflections on the river. Nearby, the mysterious Iya Valley tempts explorers with vine bridges, onsen baths, and remote thatched-roof villages that feel untouched by time. Whether you're chasing adrenaline or quiet beauty, Oboke & Koboke delivers a unique blend of natural grandeur and cultural depth. 🚆 Access via JR Oboke Station on the Dosan Line. Best visited from spring to fall. #obokekoboke #tokushima #japannature #cityplaybook #hiddenjapan #adventuretravel #iyavalley #whitewaterrafting #sightseeingjapan #traveljapan
