A giant panda at Tokyo's Ueno Zoo, named Shin Shin, gave birth to a cub on Monday. The birth of a panda cub at Ueno Zoo is the first in 5 years.
The zoo observed copulations between Shin Shin and a male panda Ri Ri in late February.
Zoo officials had been preparing for Shin Shin's potential delivery since last month, when she started showing signs of pregnancy.
