Giant pandas Rauhin (left) and Saihin are exhibited outdoors for the last time at the Adventure World theme park in Shirahama, a resort town in Japan's Wakayama Prefecture, on Sunday, before being returned to China. Adventure World announced on April 24 that it will return all four giant pandas in captivity at the park to China around the end of June. The four pandas are 24-year-old Rauhin, the first panda born at Adventure World, and 8-year-old Yuihin, 6-year-old Saihin and 4-year-old Fuhin, all females born to Rauhin, who has given birth to a total of 10 pandas and is well-known as a "veteran mom".
