About Waza to Kokoro Seminar
Waza to Kokoro: Hands and Heart is the Japanese Garden Training Center’s flagship program. This program helps Japanese gardens outside of Japan find authentic, locally-appropriate solutions in design, construction, maintenance, and preservation. It is designed for professionals working in Japanese gardens, but is also open to landscape design and construction professionals as well as students of landscape-related disciplines. We are a Landscape Architecture Continuing Education System accredited provider.
Our 2025 seminar is at the beginner level. It will focus on stonework taught in the traditional hands-on method offered in the context of the culture of the Way of Tea–an immersive learning experience of not just the techniques but the cultural heart of the Japanese garden. It will be held at Portland Japanese Garden and offsite venues, where participants will get a chance to explore and learn from its authentic techniques, design, and composition.
True to its philosophy of combining the western teaching and eastern teaching, everything will be taught in English. This year, our Garden Curator and Director of Japanese Garden Training Center, Hugo Torii, will lead the seminar and we will also have a guest instructor from Japan.
Seminar Core Focus
The seminar’s core focus is on stonework in the Japanese tea garden, taught by visiting Japanese instructors and Portland Japanese Garden staff. A traditionally-grounded, hands-on learning process is supplemented with preparatory cultural instruction and theoretical knowledge, with content including:

Mark Bourne
Owner, Windsmith Design
Mark Bourne is a Japanese-trained master garden creator and a scholar of Japanese garden history. After completing a bachelor’s degree in Anthropology and Japanese, he traveled to Kyoto to study the craft of Japanese gardens, a move that turned into a full, four-year-long apprenticeship to renowned garden creator Yasuo Kitayama. Under Kitayama, Mark went through the same rigorous, multi-year discipline that has defined the Japanese tradition for centuries. This training included maintenance, restoration, and new work in many famous and historically significant gardens, including the Kyoto Imperial Palace, Katsura Imperial Villa, Kenninji, Kodaiji, Daitokuji, as well as significant new garden construction projects such as the Kyoto-Florence sister city garden in Florence, Italy, and the gardens for the Itchiku Kubota Art Museum in Kawaguchiko, Japan. In addition to design and construction training, Mark earned a master’s degree in architectural history, with a thesis based on translations of work related to the Meiji period garden Murin-an. As a teacher and a designer, Mark is particularly interested in the delicate balance between innovation and continuity that keeps the tradition relevant, without abandoning the rich history that provides the foundation for practice.
