Todai-ji Great South Gate(東大寺南大門), built in the early Kamakura period, has been studied as a representative example of Daibutsu-yo(大仏様) architecture. There are many studies about it from the aspects of the style and technique of Daibutsu-yo, the relationship with Chinese Song Dynasty architecture, the construction organization of Todai-ji Temple, the achievements of Chogen(重源) and Todai-ji Great South Gate itself. Studies from the viewpoint of Daibutsu-yo technic are mostly focusing on the detail. On the other hand, Daibutsu-yo should have introduced mainly for the reconstruction of the Great Buddha Hall of Todai Ji Temple(東大寺大仏殿) as a huge building, the whole structure and its assembly process should be considered in an important meaning. Among many precedent studies, 「東大寺南大門の構成部材—軸部の肘木と貫」by Ike Kozo(池浩三) focused on the assembly process of Todai-ji Great South Gate, it based on the Report book of repair construction (『東大寺南大門史及 昭和修理要録』). In this paper, they paid attention to the joint of shaft horizontal inserted to the column of Todai-ji Great South Gate, examined constituent components of it, made a model of it and estimated its assembly process. The result showed that the construction of Todai-ji Great South Gate was very reasonable and dynamic. In their study, Todai-ji Great South Gate was considered as perfect mirror symmetry, but an observation of crosspiece holes and wedges in this research proved that there are many irregular positions. Therefore, it was necessary to examine the type and arrangement of main components of Todai-ji Great South Gate, and to reconsider the construct sequence of column, crosspiece and inserted bracket arms (Sashihijiki) This paper was based on an observation of crosspiece holes and wedges in field survey, re-inspected the joints and shape of main components of Todai-ji Great South Gate’s main framework recorded by the Report book of repair construction, revised their position and then aimed to restore the assembly process. The examination is carried out by the following method. 1. Examined the peculiar description method in Report book of repair construction. 2. Based on the observation in field survey, made the actual condition of crosspiece holes and wedges clear, analyzed the shape of joint, the shape of crosspiece inserted to the crosspiece holes vertically and horizontally and their assembly order. 3. Re-inspected the types and dimensions of components recorded by the Report book of repair construction, revised their position. 4. Based on the above restored the assembly process of its main framework. The result showed that even Daibutsu-yo has some common characters with Chinese Chuandou (穿斗式), it was obvious that it has its unique assembly process, which brought up a new perspective for discussing the origin of Daibutsu-yo.
