Upon reaching Taiwan and unloading her cargo, "Ryūhō" was among the targets of a major series of American carrier-based air raids all over the island. Twelve TBF Avengers attacked her, but none scored a hit, and "Ryūhō"s gunners shot down one of them. "Ryūhō" departed for Japan on 2 January 1945 escorted by "Isokaze"; when she arrived at Kure on 18 January, "Ryūhō" also gained the distinction of being the last Japanese aircraft carrier to venture outside the home waters of Japan.
