Chuta Ito the historian of architecture surveyed the historical buildings in Okinawa. Ito gave them the name of “Ryukyu architecture”, and positioned it as one of the type of Chinese architecture. On Okinawan side his valuation of “Ryukyu architecture” was broadly embraced around the intellectuals. And in 1930's the movement to try to designate “Ryukyu architecture” as National treasure toned up, because regional society needed to insist on the value of Okinawan culture against the government through it. Behind it there was the will of regional society to assimilate into the nation state rapidly and to remove the cultural discrimination between “Japan” and Okinawa.
