San'nai-Maruama site is the remains of village about 5,500 to 4,000 years ago.
The period is called as Jomon Period in Japan.

It is located about 4 km southwest of Aomori station.

The remains have been known since the 17th century, but it had been considered that they are not so important.

In the 20th century, they were sometimes excavated only partly.

But, in the early 1990s, Aomori Prefecture planned to build a new baseball stadium here, then they started a full-scale investigetion of this site.

Then, in 1994, they found that they are the remains of large-sized village and the size was the largest in Japan.
Therefore, they halted the construction of the studium and started preserving and maintaining this site.
