Most texts suggest that the Imperial Hotel, built in Tokyo 1916-1922, and which survived the earthquake of 1923 which destroyed many buildings constructed around the same time by Wright's sceptics and detractors, was demolished in 1968. As can be seen from the pictures below, the lobby of this exquisite building was in fact saved, and moved to a "museum", Meiji Mura, just outside Nagoya.
