− The Udo hut in Sanda City −

Abstract

This paper intends to identify the construction of the thatch roofing using the rice straw. I researched for the “udo hut” built for cultivate the udo in Sanda city. The hut’s roof was made using the “toma” that was braided in the form of cloth. The toma was the roof’s material set the rice straw in line beforehand. The farmers completed the roof in one day by roll out the toma on the roof. The rice straw’s 45mm-thick roof kept the room’s temperature above 10 degrees C in the winter. This rice straw roof seems to be one of the most flat in the thatch roofing in Japan.
