with the World
A journal on tree diagnosis, garden design,
urban greening, and planting management from Japan.
Concept
Trees are storytellers
of Japan's culture,
landscapes, and future.
Japan Blue Arborist Journal is an international journal on Japanese arboriculture and tree culture. From field diagnosis to garden aesthetics and urban greening challenges, true arboriculture knowledge emerges where scientific insight and practical experience converge.
We explore how trees are understood, cared for, and passed on across generations-from sacred groves to urban streetscapes. This journal shares the stories of trees and the people who work with them.
