Visitors pose for pictures with female giant panda Xiannu, named Shin Shin in Japan, eating bamboo in the background at Ueno Zoological Park in Tokyo April 1, 2011, on the first day its appearance with a fellow male panda, Bili, named Ri Ri in Japan, to the public. Xiannu and Bili, both five years old, who arrived from China's Sichuan province in February, were shown to the public at Ueno on Friday, marking the first viewing of pandas in Japan in three years. The appearance of the two giant pandas coincides with the reopening of the zoo from a temporary closure, following the massive March 11 earthquake and tsunami in northern Japan. [Photo/Agencies]
