He is a leading figure in the Japanese treehouse world, creating treehouses based on the knowledge and sensibility he has cultivated in Oregon.
In 1994, while wandering around the world, he became the only Japanese participant in the World Treehouse Conference held annually in Oregon. Since then, he has been creating treehouses that are suited to the climate and trees of each region, not only in Japan but also globally, and continues to propose a free and rich worldview that is not bound by existing frameworks.
