Sika deer from Nara Park entered a residential neighborhood on Tuesday, walking along roads and eating garden crops [1, 2].

The incident highlights a growing conflict between urban expansion and wildlife management as the deer population reaches record levels. These animals are identified as a national natural monument, complicating efforts to manage their movement outside designated areas [1, 2].

Footage from the event showed five deer crossing a pedestrian crossing [3]. After merging with another group, the total number of deer in the area reached eight [3]. The sighting occurred on a residential street approximately two km northeast of Nara Park, directly in front of JR Nara Station [1, 2, 3].

Local officials attribute the spillover to a surge in the deer population following the COVID-19 pandemic. According to the Nara Prefecture Forestry Department, the deer population increased by 360 individuals in fiscal 2025, marking a record high [2].

Wildlife experts suggest the overpopulation is driven by human behavior. Dr. Yamada, a wildlife scholar, said that excessive feeding by tourists is a primary factor in the population spike [2].

This trend of deer establishing presence outside the park boundaries is becoming more common. Nakanishi, vice chairman of the Nara Deer Preservation Society, said the current situation where deer settle outside the park is being referred to as "mini-Nara Park-ification" [1].

The deer continue to roam residential zones, where they frequently target private gardens for food [1, 2].

“The deer population increased by 360 individuals in fiscal 2025, marking a record high.”

The movement of Sika deer into residential areas reflects a breakdown in the traditional boundaries of Nara Park. As the population grows due to both post-pandemic trends and tourist feeding, the deer are forced to seek new food sources, turning urban gardens into foraging grounds. This creates a systemic challenge for city officials who must balance the protection of a national monument with the property rights and safety of local residents.
