But after the king's death, Kunigami and Gusukuma broke their promises and wanted to install other the prince, Shō Kanshin (Japanese: 尚 鑑心), as the new king instead of Shō Gen. They said that Shō Gen was too sickly to succeed the throne, and many ministers supported them. It made Aragusuku very angry. He stood in the audience hall, with a naginata in his hand, and said that Shō Gen was the eldest son of the Queen Umimajingani Aji-ganashi, so he should be the new king because of the primogeniture. Kunigami and Gusukuma were afraid of him and never said a word. All ministers agreed with him. Finally, Shō Gen ascended to the throne successfully. In the year 1559, Aragusuku exiled Kunigami to Kume Island and Gusukuma to Iheya Island.
