Emperor Yūryaku
Like the "chigi", the "katsuogi" was initially reserved only for the powerful nobility. It was first described in the "Kojiki", a 7th-century Japanese text, where it seemed to be something accessible only to the emperor. In the excerpt, Emperor Yūryaku (418–479) sees an official's house laden with "katsuogi" on the roof. Angered by this, he pronounces the official a knave and a scoundrel for building a house in imitation of the imperial palace.
