The panda fans gathered at Tokyo's Ueno Zoo for one last look at Xiang Xiang, the park's idol since her birth in June 2017.

Sunday's viewing was limited to 2,600 lucky ones who won their tickets in an extremely competitive lottery. But many others who didn't win came anyway to say their goodbyes from outside of the panda house.

"Xiang Xiang is not only cute but charming and funny. She's so attractive that if you see her once, you want to see her more. I don't think there is any panda like her in the universe," said a visitor who only gave her first name, Yukie. "I've made friends here by sharing it, and that is also her attraction."

Though she was born and grew up at the Tokyo zoo, Xiang Xiang, whose parents Ri Ri and Shin Shin are on loan from China, must return to that country.

China sends pandas abroad as a sign of goodwill but maintains ownership over the animals and any cubs they produce. The animals are native to southwestern China and are an unofficial national mascot.

Divided into groups of about 10, the visitors were given only a few minutes to quietly say goodbye to Xiang Xiang as she nonchalantly nibbled on bamboo sticks. Viewers held up their mobile phones and cameras to capture her every move.
