Tokyo's Ueno Zoo is contemplating a complete smoking ban before female giant panda cub Xiang Xiang goes on public view in December — the first Tokyo zoo to do so, its operator said.

"With the announcement of the panda cub, we're expecting a surge in the number of visitors," Tokyo Zoological Park Society official Takahiro Kogo said Monday.

Kogo explained, however, that the move has been under consideration for some time to deal with secondhand cigarette smoke in parks across Tokyo.
