Le mobilier inclut de la céramique des types Iha, Ogidō et Katoku I, tous correspondant au Kaizuka Ancien (2000-1000 BC)*. Le site a également livré des pierres à moudre, des coquillages, des os de poissons et de dugong, mais aucune habitation pour le moment. À l'époque, le niveau de la mer étant plus élevé, le site se situait probablement à l'embouchure de la rivière Yona-gawa, fournissant un accès à la fois aux ressources marines et fluviales. L'absence d'habitation laisse penser qu'il était utilisé comme base de pêche par les habitants d'un habitat à proximité, et que les repas étaient préparés sur place dans les fours polynésiens.
Les fouilles se poursuivront jusqu'en février prochain et la publication du rapport de fouilles est prévue pour 2016. Je l'attends.

One earth oven is good. Thirty-five earth ovens is better (probably)
Awayonagawabaru Site (安和与那川原遺跡, Okinawa Prefecture, Nago City, Aza Awa) was discovered in 2007 by a reconnaissance survey before the implementation of works to limit alluvial deposits in Yona-gawa River. It is right in front of Awa Shellmound (安和貝塚) on the other bank, but the two sites belong to different periods. The site is 1840 m² large and has been excavated since June 2014. In January this year, an area about 500 m² large had been surveyed, in which the remains of thirty-five (35) earth ovens had been discovered. It is the largest number of earth ovens found in one site for the whole Okinawa Island (since it is précised it is Okinawa "Island", I suppose a larger number of earth ovens have been found in another site in Okinawa "Prefecture", but I have yet to find this site). Those structures are circular, composed of burnt cobbles, ashes and charcoal, and, as stated above, are interpreted as earth ovens (principle of the earth oven: you dig a hole, pave it with stones, put the food inside –generally wrapped in leaves–, cover with tree branches, leaves, combustible, lit fire and wait).
Artefacts include sherds of the ceramic types Iha, Ogidō and Katoku I, all of them belonging to the Early Kaizuka Period* (2000-1000 BC). The site also yielded handstones, shells, fishes and dugong bones, but no dwelling for the time being. At that time, the sea level being higher, the site probably lay by the estuary of Yona-gawa River, with a direct access to both sea and river resources. The absence of dwelling implies it might have been used as a fishing facility by the inhabitants of a nearby settlement: meals taken there were prepared in the earth ovens.
Excavations will be carried until next February and the report will be published sometime in 2016. Will sure be waiting for it.
* Early Kaizuka: Broadly contemporaneous with Late Jōmon
