Syoso classified the four important structures, Maruki-kura Ko-kura Ita-kura Do-kura in the Kodai Period. Maruki-kura meant log-type storehouse, Ko-kura shaved log-type to the heaxgonal section (Ko-Azekura, Azekura), Ita-kura plank-type used Otoshihame-system, Do-kura clay-type. Oku, Kurashita, Kurashiro, they were applied correspondingly to Syoso. In the Yayoi period, there were the storehouses for rice-ear looked like barn-style, made by the thin timber. Next the Kofun period, the storehouses appeared that made by the big timber and the plank between the posts. The beginning of the Kodai period, Azekura-system came over the sea from the continent. In seven century, the Japanese government requested to make the big granary for rough rice, so Ko-kura (Ko-Azekura) were borned for the granary like the silo. Because Ko-Azegi were firm and made easy like log-style. But by the shortage the big timbers and the limitation of the planning, so Ko-Azekuura were reduced to change the Ita-kura soon, and Ko-Azekura became used to the Treasure. Ita-kura, plank-system, were spreabed, and became the tradion of Wahu (Japanese style). In nine-ten century, the government not intended to much storage the rice. But the fire-proof structure were very important, and there were spread the Tawara (straw bag). So Do-kura made much popular in place of Ita-kura.
