In this study the author considered (1) the reason why "Tsuchi-mikado-dono" was used as Imperial Palace in early 14 C.A.D., (2) the scales of its site and buildings, and (3) the plan, the function and the character of "Ko-go-sho" in the same Imperial Palace "Tsuchi-mikado-dono". In conclusion, the antecedent of this palace "Tsuchi-mikado-dono" was the Palace of "Yo-toku-mon-in", a member of Imperial families, and this building continued from 1317 to 1401 A.D. as Imperial Palace. As a result, we could find a type of Imperial Palace in the Northern and Southern dynastic period and a type of noble class' living house in late Kama-kura period. It was also concluded that the origin of "Ko-go-sho" might be "Ko-shin-den", sub-ceremonial buildings in noble class' living houses in Hei-an period.
