Japan turns to AI to save cherry blossoms
The service aims to preserve these iconic trees and support the cultural tradition of cherry blossom viewing by informing users about the trees’ current conditions.
Cherry blossom enthusiasts in Japan can now play a direct role in preserving the nation’s beloved trees through a new AI-powered service launched by Kirin Brewery. The ‘Sakura AI Camera’ allows users to snap photos of cherry trees with their smartphones, which AI then analyses to determine the trees’ age and overall health.
Available for free through a web browser, the tool guides users on how to take proper photos. The AI assesses each tree’s condition based on trunk thickness and shape, assigning a vitality rating on a five-level scale. The data is then shared with local governments to help identify which trees need maintenance, such as pruning or pest control.
Kirin introduced the service ahead of Japan’s 2025 cherry blossom season when people traditionally gather under the blooming trees. Many of the cherry trees planted during Japan’s postwar reconstruction are ageing, and the company hopes this technology will support long-term preservation efforts.
With local governments in Japan often facing staff and budget constraints, Kirin says the service empowers the public to contribute to conservation simply and meaningfully. ‘We want people to use this to learn about the current situation around cherry blossoms,’ a company official said.
