Tourist Spots

Iya Valley
Iya ValleyIya region is located far deeper western part of Tokushima Prefecture. This region used to be one of the regions far remote and hard to access in the mountain. Some improvement has been made in recent years, but this area is still called the Iya Valley region because of the hard accessibility. Because of this situation, the original natural beauty, including some historic vine bridges and the remote local village life are still maintained and this is why it has become the tourist destination among remote retreat seekers.
