Until recently, three other prefectures (Okinawa, Hokkaido, and Kumamoto) also did not have any national treasures, but each got one in the last few years; regarding Okinawa, in 2006 the materials related to the Daini shoshi (the second royal family) of the Ryukyu Kingdom were named a national treasure, while Hokkaido's clay figurines were named a national treasure in 2007, and the main hall and so forth of Aoi Aso-jinja Shrine in Kumamoto were designated national treasures in 2008.
