The ceramic industry that directly led to today's Shigaraki ware began in earnest in the mid-Kamakura period, during the 13th century. What was being made back then were not works of art or luxury items. The core production consisted of practical "tools" indispensable to the daily, agriculture-centered lives of the people, such as large jars (kame), pots (tsubo), and grinding bowls (suribachi).
What's particularly fascinating is that Shigaraki ware of that time was heavily influenced by the more technologically advanced Tokoname ware. This shows that Shigaraki ware didn't start on a unique path from the beginning, but rather by learning and incorporating superior techniques from other production centers. Its products were designed with functionality as the top priority, and distribution was limited to nearby regions like Omi (present-day Shiga Prefecture), Kyo (Kyoto), and Yamato (present-day Nara Prefecture). During this era, Shigaraki ware was not yet known nationwide; it was a craft that supported the lives of local people.
