Iga Province

Iga Province (伊賀国, Iga no kuni) was a province of Japan located in what is today part of western Mie Prefecture.^[1] Its abbreviated name was Ishū (伊州). Iga is classified as one of the provinces of the Tōkaidō. Under the Engishiki classification system, Iga was ranked as an "inferior country" (下国 gekoku) and a "near country" (近国 kingoku).

Iga was bordered by Ise to the east and south, Ōmi to the north, Yamato to the west and south, and Yamashiro Province to the northwest. It roughly coincides with the modern municipalities of Iga and Nabari in Mie Prefecture as well as Yagyu in Nara Prefecture. Surrounded by mountains, historically, Iga Province was rather inaccessible due to extremely poor road conditions. However, the area is now relatively easy to access from nearby Nara and Kyoto, as well as the larger cities of Osaka and Nagoya.
