Fencing known as kekkai (pronounced "keck-aye")

Do Not Climb the Trees This initiative is part of a Legacy Tree Conservation project, in partnership with the Chicago Park District led by Japanese Master Gardener, Kurato Fujimoto and Ron Henderson, Landscape Architect, Director of Landscape Architecture and Urbanism, IIT and Japan-U.S. Friendship Commission award-winning artist.

Fujimoto and Henderson have long collaborated on legacy tree preservation projects using hoozue (pronounced "hoo-zoo-ay"), that you see before you. An indigenous Japanese technique that employs wooden crutches or braces to support vulnerable branches of historic trees. Their work has earned honors from the Providence Preservation Society and the American Society of Landscape Architects for conservation projects at Roger Williams Park (Providence, RI), the U.S. National Arboretum (Washington, DC), and Dumbarton Oaks (Washington, DC). You can see larger examples of hoozue application on our trees inside the Osaka Garden.

Erected 2026 by Chicago Park District.
