Sai On's attempt to resolve contradictions between the traditional Okinawan narrative and Chinese sources was a source of another inconsistency. The "Chūzan Seikan" (1650) suggested that the Aji of Shimasoe-Ōzato had been the King of Sannan. Because Sashiki, Shō Hashi's stronghold, neighbored Shimasoe-Ōzato, his conquest must have started with the overthrow of the Aji of Shimasoe-Ōzato. Even though Sai On put Shō Hashi's conquest of the King of Sannan at the final phase of his conquest, he somehow kept the episode of Shō Hashi's takeover of the Aji of Ōzato in his early years. To resolve the new contradiction, Sai On had to re-identify the Aji of Ōzato in question as the Aji of Shimasoe-Ōzato while the King of Sannan, annihilated supposedly much later, was identified as the Aji of Shimajiri-Ōzato.
