Tokushima is located on Shikoku which is the smallest of the four main islands of Japan. It is two-and-a-half-hour bus ride away from Osaka. Tokushima might not be at first a place people would think to visit while in Japan, but it has some fascinating sights, one is the Naruto whirlpools that you can observe few times a day, there are only few places in the earth that are known for the natural occurring whirlpools like this. Other things that you can find from Tokushima is the Awa Odori dance hall where you can watch the dances and even join in after the show. Or you could spend your day at the mountains hiking to the Okuiya Double Kazura vine bridges and crossing them if you dare.
