Sannai Maruyama Ruins

The Sannai Maruyama Archaeological Site represents one of Japan's most significant prehistoric settlements, dating from the early to middle Jomon period (approximately 5900-4200 years ago). Located in Aomori City in northern Japan, this expansive site was discovered in 1992 during construction work and has since been designated as a Special Historic Site by the Japanese government in November 2000. In July 2021, it became part of the UNESCO World Heritage inscription as one of the "Jomon Prehistoric Sites in Northern Japan."

The archaeological site demonstrates the sophisticated nature of Jomon civilization through its planned settlement layout featuring pit dwellings, pillar-supported structures, and organized community spaces. The site sits on a coastal terrace at approximately 20 meters elevation along the Okidate River, strategically positioned near abundant aquatic resources and deciduous broadleaved forests. This location provided the ideal conditions for a thriving prehistoric community that existed for over 1,700 years.

Visitors can explore authentic reconstructed Jomon-period buildings including the famous large pillar-supported structures that showcase advanced prehistoric architectural techniques. The Sannai Maruyama Jomon Culture Center houses approximately 1,700 archaeological artifacts, including about 500 Important Cultural Properties excavated from the site. Notable exhibits include large flat clay figurines and a distinctive Jomon pochette (pouch), offering insight into the daily lives, crafts, and spiritual practices of Japan's prehistoric inhabitants.

Free guided tours in English are available upon request and highly recommended for understanding the site's historical significance. These hour-long tours are conducted by knowledgeable volunteer guides who provide detailed explanations of the excavation discoveries and Jomon lifestyle. Visitors can also borrow audio players at the information desk to access English commentary for video presentations.

The site is easily accessible from JR Aomori Station via city bus directly to the Sannai Maruyama Iseki stop, taking approximately 20-30 minutes. From JR Shin-Aomori Station, a convenient 15-minute shuttle bus service operates regularly. Visitors arriving by car can reach the site in 5 minutes from the Aomori Interchange on the Tohoku Expressway, with parking facilities available on-site. Admission to the Sannai Maruyama Jomon Culture Center is ¥410 for adults (¥330 for groups). The site offers comprehensive facilities including detailed English-language information materials and well-maintained pathways suitable for all visitors exploring this remarkable window into Japan's prehistoric past.
