Four newborn white tigers are the latest stars of the Tobu Zoo, north of Tokyo.
The unnamed cubs are the first white tigers born in captivity in Japan, and at six weeks they weigh in at a healthy five kilograms or about 11 pounds.
With fewer than 200 of the species left in the wild, eager visitors were happy to stand in line for over an hour to get the first peek at the rare felines.
In Japan there are about 30 white tigers held in captivity.
Although beautiful, the creatures' appearance is actually caused by a recessive gene that also causes deformities in the spine and kidney problems.
Zoo staff of course hopes that their white cubs will live to become healthy, full grown adult tigers.
