Higashimyo Wet Site, Japan, Update and News

Update reports provided by Professor Akira Matsui on the spectacular Higashimyo wet site:

 Higashimyo News 3-5-10  and 


I went to Higashimyo yesterday (3-1-10) and discussed how we could preserved the rest of the site by monitoring the PH, Ev and other chemical conditions.

Importance of this site:  Higashimyo is dated to the late initial Jomon period.  The AMS radiocarbon date of a basket made of Aphananthe aspera is 6976 + 36 BP (5891-5790 yrcalBC).

Finding so many Initial Jomon shell middens is an exceptional incident in this country.  The scale of the site is one of the largest in western Japan.  It is also rare and academically valuable that settlements, a grave yard, shell middens, and storage pits were found at the same time.  Some of the unearthed artifacts such as ornaments made of shell and animal bones are especially uncommon.  The baskets and wooden containers are the oldest found in the country.  Discovery of these artifacts has a dramatic impact on our image of initial Jomon culture.  While shell middens in Japan have rarely been excavated as thoroughly as we have done at this site, it is expected that various articles from this site will provide us with important clues to understanding ancient lifestyles and cultures.

In the belief that the Higashimyo Site is one of the rare and very important archaeological sites in the country, studies toward the preservation of Middens No. 3 and 6 has commenced.
