Okawa Village

Kochi Prefecture · Village

Okawa Village, surrounded by the Shikoku Mountains and bordering Ehime Prefecture, has the smallest population of any municipality in Shikoku. It once prospered from the Shirataki Mine and forestry, but its former center sank under the lake when Sameura Dam was completed. Okawa black cattle and Hachikin local chickens are raised.
