One of Japan's most unique attractions is facing a very modern-day threat.
Since March, six deer at the ancient capital of Nara have died with plastic in their stomachs, reports Quartz. One reportedly had 4.3kg of plastic bags in its guts.
Nara Park is a Unesco World Heritage Site and is home to over 1300 wild deer roaming freely.
They are famously friendly, some bow before receiving treats from visitors. They are only supposed to be fed deer-friendly senbei crackers, made from wheat flour and rice bran and bought from vendors.
Officials have been posting signs asking tourists not to throw away their trash, as the deer cannot differentiate plastic from food.
Nara Park, which is 45km from Kyoto, is home to the largest wooden building in the world.
The animals were considered sacred after a Shinto deity was said to have ridden to Nara upon a deer from Kashima Shrine.
