五斗長垣内遺跡
Awaji’s premier archeological site was only discovered about 15 years ago. It’s located high up a hill amongst the farms which dot the inland area of Hokudan, in the north of Awaji. Research has discovered that the site was a settlement during the Yayoi period of Japanese history, roughly 2000 years ago.
The site is notable for the remains of iron forgeries: ancient Awajians are believed to have used iron ore imported from Korea to manufacture tools for local use, and the site is thus an important example of the way even Awaji was linked to international trade within Asia in ancient times.
Today, there isn’t a great deal to see at the site. Some of the thatch dwellings of 2000 years ago have been reconstructed, and a small museum presents information and houses a few artifacts. The site’s isolated location offers fine views over Hokudan though, and anyone interested in Awaji’s ancient history will enjoy a visit here.
Access to the Gossa Iron Age Site is free. There is no public transport. You can read more about it on the site’s webpage or on Wikipedia, but only in Japanese. The on site museum has English translations of some of their information.
