The panda "Shang Shan" left the Ueno Zoo on the morning of the 21st and left Narita Airport for China, the destination of the return, before 1 pm.
Shanshan was born six years ago in June 2017.
Weight was 147 grams at 2 days old.
At Ueno Zoo, there had never been a panda born through natural mating and successfully grown up, so Xiang Xiang attracted a lot of attention.
