Yoshinogari Keitai-Guide
Both unhulled rice and rice ears from the Yayoi period have been discovered. It is known that in the Nara period rice was garnered in storehouses for the purpose of taxation in both unhulled form and as ears. Storehouses containing ears of rice were used for rice that would be threshed and consumed in a comparatively short time. Storehouses with unhulled rice were used for long-term emergency stores. From the excavated rice, it is thought possible that there were also storehouses for two kinds of rice in the Yayoi period. The storehouses likely to have been located in the area close to the entrance to the moat-enclosed settlement were those where the people of the Yoshinogari moat-enclosed settlement stored the ears of rice that they would use for food. The walls of the storehouses for ears of rice were made of grass for better air conductivity.
