Curtain call as 'adorable' panda makes zoo debut

Visitors will be limited to 2,000 a day to minimize stress on cub

A "panda boom" is in the air in Japan, as Tokyo's Ueno Zoo begins a limited public exhibition - two and a half hours a day - of its six-month-old giant panda cub, Xiang Xiang, on Tuesday.

The toddler, small enough at birth to fit in the palm of a hand, now has typical panda markings and weighs around 12 kilograms.
