The purpose of this research is to demonstrate the original of modern Noh Theater that we named it no Gakudo through giving up establishment process of Aoyama Imperial Palace Noh stage and Nhogakusha. The basic plan composition of the Nhogakusha that became the first no gakudo appears to have continued that of Edo-period Noh venues, but spatially, the outside audience seats moved indoors, and a complex composition with the seats and appending gakuya buildings surrounding the Noh stage was created. In the back, a temporary lean-to roof was erected, which resulted in an architecturally immature form. However, it was here that the history of the no gakudo began.
