 Conder taught history of oriental architecture using James Fergusson's works which insisted that there was no substantial architecture in the Orient except Mughal architecture, a kind of Saracenic architecture.Conder believed Saracenic based style might be suitable for modern Japan, and utilized it as Pseudo-Saracenic style for his early works including the Tokyo Imperial Museum, the retail shop of the Hokkaido Development Authority and the Rokumeikan..This style was limitedly accepted by Tatsuno Kingo for his design of the Kokugi-Kan (National Sumo Wrestling Hall), and Conder was very disappointed that most of his students did not understand his intention.
