Nara Park is the 660-hectare green space that ties together Todai-ji, Kasuga Grand Shrine, Kofuku-ji, and the National Museum in a single walkable area. The park is open and free; you simply arrive and walk. What makes it unusual is the 1,200 or so sika deer that roam it freely, considered sacred messengers of the gods and protected by law since 1637.
The deer are accustomed to tourists and boldly approach anyone who might have food. Vendors at the park entrances sell shika senbei — flat rice crackers — that the deer have learned to associate with humans. They will bow their heads in a begging gesture, nudge pockets, and occasionally become pushy. Small children are sometimes intimidated; most adults find them delightful. The deer have learned that bowing prompts the crackers, which is either an example of animal intelligence or a comment on human behaviour, depending on your perspective.
The park is particularly beautiful in autumn when the maples turn, and in early April during cherry blossom season. Summer evenings bring fireflies near the streams.
