In 734, Abe tried to return to Japan, but the ship that was to take him back sank not long into the journey, forcing him to remain in China for several more years. In 752, he tried again to return, with the mission to China led by Fujiwara no Kiyokawa, but the ship he was traveling in was wrecked and ran aground off the coast of Annan (modern day northern Vietnam). He managed to return to Chang'an in 755.
After the An Lushan Rebellion started later in 755, it became unsafe to return to Japan and Nakamaro abandoned his hopes of returning to his homeland. He took several government posts and rose to serve as Duhu (Governor-protector) of Annam between 761 and 767, residing in Hanoi. He then returned to Chang'an and was once again planning his return to Japan when he died in 770, at the age of 72.
Abe was a close friend of the Chinese poets Li Bai and Wang Wei, Zhao Hua, Bao Xin, and Chu Guangxi.
