What is the Sannai Maruyama Site?
The Sannai Maruyama Site (Sannai Maruyama iseki) is one of Japan’s largest Jomon-period settlement sites, located in Aomori City, Aomori Prefecture. It is famous for revealing a large-scale settlement that flourished from about 5,900 to 4,200 years ago.
This site was inscribed in 2021 as part of the “Jomon Archaeological Sites in Hokkaido and Northern Tohoku” on the UNESCO World Heritage List, and it has become an important spot for learning about Japanese history and culture.
The grounds include reconstructed Jomon-era dwellings and raised-floor buildings, and well-equipped facilities where you can experience life from that time.
It’s recommended not only for those interested in archaeology and history, but also for families and tourists!
