Japan's largest ancient Ruins made public

Japan begins an extended spring holiday-week, from Thursday until next Wednesday.
In the western prefecture of Saga, excavation work on the nation's largest Yayoi-period ruins, dating back to 300 B.C., is being opened to the public for the week.

The Kamekan cemetery in the Yoshinogari ruins was built nearly 2100 years ago.
The site contains 4 ceramic coffins, 60 centimeters in diameter.
1500 such coffins are known to still stretch in a 600-meter line underneath the site.

On Friday, elementary school children visited the site as part of their social studies and listened to an explanation from prefectural officials. The children also observed delicate work to restore earthenware in a park museum.

Normally, excavation work is suspended on weekends and national holidays.
But park officials are making an exception during the spring holidays to accommodate visitors.

Excavation research will be open till Sunday and the restoration work, till Wednesday - the final day of the holidays.
