Sanuki Province, Ancient province in Shikoku, Japan
Sanuki was a province in northeastern Shikoku that extended from inland regions to the Seto Inland Sea, including the Shiwaku Islands. The territory encompassed diverse landscapes with mountains, plains, and coastal areas.
The province was transformed into Kagawa Prefecture during major administrative reforms in 1871, when Japan modernized its governmental system. This restructuring marked the end of the traditional provincial order in the region.
The region holds deep ties to Buddhist monk Kōkai, who spent his formative years here before establishing the Shingon tradition. Visitors can still find temples and sacred sites connected to his spiritual influence throughout the area.
The former provincial territories now make up Kagawa Prefecture, with the ancient capital site located in present-day Sakaide city. Visitors can explore the region using local transportation and access historical sites spread throughout the area.
The region was classified as an upper country in the medieval Engishiki ranking system, reflecting its significant administrative role. This classification shows it ranked among the most important provinces in ancient Japan economically and administratively.
