If you ever dreamed of a place full of deer, Nara Park (in Nara, Japan) would be it for you--over 1,000 deer are known to roam around the park.
Japan is known for having its ethnic religion "Shinto" that has been prevalent from the 8th century. And in Shinto, deer is believed to be a god's messenger.
According to the officials of the park, these furry messengers could get aggressive if you tease them with feed. So, don't.
