Kirin Brewery Launches World’s First Sakura AI Camera to Preserve Japan’s Aging Cherry Trees

Collaborating with local governments nationwide, Kirin Brewery launched the 'Harekaze ACTION' initiative to protect cherry trees. From the photos of cherry trees you regularly take, you can learn about their health status and estimated age. The collected cherry tree data will be sent to local governments and will become a valuable database to protect cherry trees.

As cherry blossoms bloom next week, millions will gather for hanami, unaware of a growing crisis—Japan’s aging sakura (Cherry Blossom). Many Somei Yoshino trees, planted during post-war reconstruction, are now surpassing their 70-year lifespan, increasing the risk of collapse. However, local governments often lack the resources and data needed for proper maintenance. To address this pressing issue, Kirin Brewery has introduced the ‘SAKURA AI CAMERA,’ a groundbreaking initiative that allows citizens to contribute to preservation efforts by photographing trees. This innovative technology enables AI to assess the health of the cherry trees, and the collected data supports local authorities in proactive tree care.

The public can witness the AI camera in action during hanami, where experts—including tree doctors—will be available for interviews on the aging sakura crisis and the role of technology in conservation. This initiative not only aims to protect Japan's cherished cherry trees but also to enhance the hanami experience for all.

In Japan, hanami (sakura viewing picnics) is often enjoyed with beer and food. To keep this cherished tradition alive—and to give back to the sakura trees that have long supported brewery companies during the season—Kirin Brewery is stepping up to protect them.

The new service measures the health status and estimated age of cherry trees using AI judgment through smartphone cameras, creating a database to be disclosed to users and local governments.

The collected cherry tree data will be provided to local governments, assisting in planning for tree planting, removal, and maintenance.
