Oboke and Koboke are great valleys that are located upstream of the Yoshino-gawa River in the western area of Tokushima. Ōboke (大歩危) and Koboke (小歩危) mean, big dangerous to walk along and small dangerous to walk along, respectively. The Yoshino River has cut through the Shikoku Mountains over the ages, eroding crystalline schist into winding gorges with myriad shapes and forms, which almost look like marble statues. This place has fantastic reflections of cherry blossoms in spring and full autumn colour in season.
