Awa

Awa was one of the four provinces of Shikoku within Nankaidō, the southern circuit of the Japanese state. Nankaidō combined a territorial division with a road system that linked provincial capitals and connected Shikoku to Nara and the Kii Peninsula. Travel required both overland stages and crossings of the Inland Sea and its exposed southern waters.

The route from central Japan reached the coast of Kii, crossed to Awaji and continued toward Shikoku. Awa occupied the eastern part of the island, with mountains separating its valleys from Sanuki and Tosa. Rice fields followed the rivers, while fishing and salt production supported coastal communities. Provincial governors, temples and local warriors drew revenue from these varied lands.

Medieval and later authority repeatedly reorganized the province and its roads. Military conflicts and the integration of Shikoku into Tokugawa domains changed the old provincial boundaries, but Awa remained a recognizable regional name. Its identity came from fertile valleys and maritime links: boats connected the province to the Kii Channel, while mountain passes led toward the rest of Shikoku. Ports linked local produce from coastal villages and fishermen to wider Inland Sea markets.
