Overview (history, characteristics, attractions)
Oyu Stone Circle is a Jomon period site located in Kazuno City, Akita Prefecture, and is one of Japan's most representative stone circles. Thanks to long-standing excavations and preservation work, the entire structure has been well preserved, and it has been designated a national historic site. Multiple stone circles, stone rows, and facilities thought to be for burials have been identified, and it has been suggested that they may have been related to religious rites, astronomy, and community ceremonies.
Its distinctive features include the existence of several relatively large circular structures, the orderly arrangement of standing stones and stones, and the "Oyu Stone Circle Museum (Exhibition Hall)" located on-site, which is packed with discoveries, reconstructed models, and explanations. The ruins themselves are located in a wide grassy area, and have a quiet charm that allows you to think about the lives and beliefs of the Jomon people.
Highlights
- Stone Circle Main Body: Multiple circular stone arrangements and stone rows. By looking at the layout and scale, you can get a real sense of the settlement and ritual activities of the Jomon period.
- Arrangement of standing stones and stones: Circles and rows of stones of different diameters remain, allowing us to imagine the design intentions of the time (connections to astronomical observations and seasonal events).
- Oyu Stone Circle Museum: Learn about the origins of the ruins and the results of the research through excavated artifacts (pottery and stone tools), reconstructed models, video commentary, etc. We recommend experiencing the exhibition and the ruins tour together.
- Walking paths and information boards: With well-maintained sightseeing routes and information boards, even first-time visitors can easily see the main points.
- Natural scenery: The surrounding countryside, seasonal flowers, and expansive sky enhance the tranquility of the ruins. The ruins have different appearances with each season: green in spring and summer, red leaves in autumn, and snow in winter.
