Oyu Stone Circle (Oyu Kanjorekkeki) is a massive stone arrangement located in Towada Oyu, Kazuno City, Akita Prefecture. Designated as a Special Historic Site of Japan, it was inscribed as a component of the 'Jomon Prehistoric Sites in Northern Japan' UNESCO World Heritage site in 2021. Known as a 'Kanjosekirki' (circular stone monument), this archaeological site is an incredibly precious relic that tells the story of the rituals and ceremonies performed by ancient people.
This site symbolizes the spiritual culture of the late Jomon period. While it is believed to have originally functioned as part of a settlement structure with a central plaza, it evolved over time into a massive ritual monument with significant visual impact. The existence of such a large-scale structure suggests that the society of that era possessed the organized labor and social hierarchy required to manage large-scale civil engineering and complex religious ceremonies. It served as a sacred gathering place that transcended the simple functions of a residential settlement.

The primary attraction is the arrangement of stones spread across the vast site. Visitors can witness the physical traces of history, from the settlement structures of the mid-Jomon period to the ritual monument of the late Jomon period. Additionally, the Oyu Stone Circle Museum is located on-site, offering exhibits that deepen your understanding of Jomon culture. The museum displays artifacts, including items designated as Tangible Cultural Properties of Akita Prefecture, allowing you to learn about the intricate details of ancient life and beliefs.
Located within a lush natural environment, Oyu Stone Circle shows different faces depending on the season. We recommend visiting during seasons with clear skies or when the natural colors are most vibrant. During daylight hours, the arrangement and shapes of the stones are easiest to observe, making it an ideal time to understand the historical structure. You can also enjoy the scenery where the ancient monument blends seamlessly with the surrounding nature.

Beyond simple sightseeing, this is a place for a deep 'historical experience' where you can connect with the spiritual world of people from thousands of years ago. Through the exhibits at the Oyu Stone Circle Museum, you can explore the mysteries behind why such a massive stone arrangement was created. Learning about the Jomon people's respect for nature and the importance of their rituals provides a profound connection to the roots of Japanese culture.
Oyu Stone Circle is nestled in an area of abundant natural beauty in Akita Prefecture.
