• Wakimachi, Mima City, located in the middle basin of the Yoshino River, a major river in Shikoku, is a river port town that prospered through the cultivation of indigo, known as "Japan blue," and the distribution of indigo dye, "sukumo," throughout Japan. The residences of the indigo merchants, as typified by Wakimachi, have "udatsu" firewalls as a symbol of their wealth. This potter's tour will give visitors a sense of the history of water transportation along such a long river, the history and legacy of the fight against flooding along the raging Yoshino River, the indigo dyeing technique, and the lifestyle and culture of people who have lived together with indigo.
• You can enjoy pottering with a navigator who tells you the story of the region and the spaces where people live that you cannot visit by car.

The townscape allows visitors to experience the atmosphere of the Edo period in Japan, where the culture of the indigo merchants remains strong.
