The group comprises 17 ancient sites across Hokkaido, Aomori, Iwate and Akita prefectures that reflect a hunter-gatherer society that prevailed in Japan for more than 10,000 years. If registered during an online World Heritage Committee session between July 16 and 31, the locations will be Japan's 20th World Cultural Heritage listing. Among the ruins, the Sannai Maruyama village in Aomori, which dates back around 5,900 years, features a large settlement with the remains of large buildings and roads arranged systematically. The Oyu Kanjo Resseki site in Akita, meanwhile, consists of a pair of large stone circles. The Japanese government recommended the archaeological sites to the U.N. Educational, Scientific and Cultural Organization in 2020, saying they represent an era that is believed to have begun 16,000 years ago with settlements based on hunting, fishing and plant gathering on the back of abundant food resources.
