Documenting
Japan’s Trees.
Sharing What
the Field Reveals.

To document and share
Japan's tree culture
from the field.

Japan's gardens, trees, sacred trees, old trees, urban landscapes, and greening practices hold primary knowledge that has yet to be fully shared with the world.

As a field-based practitioner in Japan, I record and communicate this knowledge through arboriculture, science, landscape practice, and cultural perspectives.

This blog explores the relationship between trees, people, cities, and Japanese culture, sharing insights from the field with readers around the world.
