The Kojiki, translated by Basil Hall Chamberlain, , at sacred-texts.com
His Augustness Oho-hatsuse-no-waka-take dwelt in the palace of Asakura at Hatsuse, 1 and ruled the Empire. The Heavenly Sovereign wedded Queen Wake-kusaka-be, younger sister of King Oho-kusaka (no children). Again he wedded Princess Karu, daughter of the Grandee Tsubura, and begot august children: His Augustness Shiraka; next his younger sister Her Augustness Princess Waka-tarashi (two Deities).
387:1 p. 387 For Hatsuse see Sect. CXLIII, Note 8. Several Asakuras are named in the pages of these "Records." That here named is in Yamato. The name seems to mean "morning store-house."
