Advanced Japanese Joinery and
Timber Framing Workshops
A Unique Opportunity

Calling all experienced timber framers: We invite you to join us this summer for a once in a lifetime workshop opportunity—learning advanced Japanese joinery and timber framing methods from two top-level traditional timber framers from Japan. These two workshops will take place as part of the construction of a timber frame straw/clay organic food store and holistic health center at Harvest Haven, Lethbridge, Alberta.
Japanese joinery was born out of the desire to create buildings with clean beautiful aesthetics, yet with the strength and resilience to survive for centuries through earthquakes and typhoons. The goal of this workshop is to demonstrate how the beauty and strength of Japanese framing can be accomplished efficiently while combining artistry with practicality.
The project at Harvest Haven will highlight a complex roof featuring traditional Japanese joinery. Focus will be on effective and productive techniques and tools while maintaining traditional aesthetics.
During the workshop you will learn how to create showpiece joinery with time-efficient joinery solutions that don’t shortchange the look or performance of your building.
Features of the workshops will be:
- advanced Japanese timber framing theory and design
- advanced timber selection and usage criteria
- advanced joinery layout
- ultra-precise cutting and accuracy skills
- confidence and discipline to cut accurately with hands-on instruction
These Japanese instructors are not just theoreticians, but successful businessmen competing with conventional steel plate and fastener systems in Japan. They provide the value customers are looking for, while taking into account quality, beauty, and economy.
An opportunity to learn from Japanese craftsmen is extremely rare in North America because of the language barrier. Language, however, is the link that brought an organic farm and a Japanese timber framer together. I became fluent in Japanese while studying for six years at a Japanese university and graduate school, and working as a translator in Japan. Many more years of speaking with my Japanese wife and Japanese farm apprentices and visitors helped to keep the language fresh. My wife and I became friends with Takahashi-san and the plan for the Japanese framing and workshop was born.
During the last two years I have been involved in learning and teaching straw/clay construction workshops and projects. You can see the straw/clay and timber frame house that we built on the farm last year. Click HERE
Yoshitomo Takahashi: Head instructor and lead carpenter on this project
After four years of strict apprenticeship as a temple framer, Takahashi-san spent two years apprenticing as a traditional tea ceremony house builder, delving into the complex psychology of design, balancing proportion with detail in studied simplicity. He has mastered the effect of a subtle unobtrusiveness that defines the beauty of tea houses and Japanese gardens.
Since 1997, Takahashi-san has operated his own timber framing company in Chiba Prefecture, east of Tokyo, where he continues to perfect his own style of traditional framing. More recently, he became famous outside of the timber framing community, having been featured on TV and at various events because of his work. 
His company's website is www.kominkakoubou.com. To view some of his recent projects, click HERE or to view some pictures in his personal blog, click HERE.
Whenever Takahashi-san finds himself on a project in need of another set of capable hands outside of his company staff, Akihiro Kitami is the framer he calls on.
Akihiro Kitami: Artisan timber framer to assist Takahashi-san
Kitami-san grew up in northern Chiba Prefecture and from an early age had ambitions of becoming a carpenter. He acquired his skills in traditional timber framing while working on heritage site building renovations where he was exposed to both good and bad aspects of traditional construction techniques. Since then, he has implemented the positive aspects of traditional timber framing for modern home construction, while ensuring that valuable skills learned over centuries are passed on to future generations.

Workshop details:
Workshop Structure: Class is informal. Basic tooling, sharpening, and layout techniques will be covered each day as needed. Each step of the project will include instruction and answers to questions.
Frame-raising is scheduled for both workshops, with the final raising in workshop II. Both workshops will cover nearly identical curriculum components.
Instruction is from 8 AM to 6 PM, with a lunch break. There will be time in the evenings to discuss theory and visit with the Japanese instructors and one another.
Requirements: Due to the advanced nature of this seminar, registration is restricted to participants with experience in timber framing.
Participants are required to bring personal framing tools such as tapes, squares, chisels, planes, hand saws, and circular saw.
Materials: Framing will be with Douglas Fir or Western Larch

*Tuition discount for tools: Some power tools will be available on site, but those who bring a 16” circular saw, chainmortiser, large power planer (minimum 6 - 12”), and other framing tools will receive more hands-on experience and will also receive a discount of $175 on tuition.
Two specialized timber framing machines (a multi-bladed tennon cutter and a large mortiser) will be brought in from Japan for use during the seminars. Though these machines are part of the standard tool kit of modern Japanese timber framers, they are not available through normal retailers in North America. Information about how to purchase them from Japan will be available.
*Special Tuition-Free Positions: Several skilled timber framers are required to fill volunteer positions for the two workshops.This is a golden opportunity to learn tuition- free from Takahashi-san and Kitami-san, receiving a full four weeks of working with them every day in exchange for assistance in organizing and running the workshops. These positions will allow for participation in every aspect of building the frame.
The positions begin the day before Takahashi-san and Kitami-san arrive and end the day they leave, for a total of six weeks (June 20-July 30). Responsibilities will include organizing and prepping for the workshops, as well as working with me during the two weeks that Takahashi-san and Kitami-san return to Japan between workshops.
The chosen candidates will have free room and board at Harvest Haven for the six weeks.
Hand tool discount: As a special offer for participants, Takahashi-san has selected high quality Japanese hand tool sets he will make available at wholesale cost– each set consists of two hand sharpenable Japanese saws, two chisels, and three sharpening stones (approximate value $400 CAD).
Class Size: is limited, so apply as soon as possible.
Applications can be sent to me at mbenson@harvesthaven.com with a résumé of qualifications (references would be helpful). More important than technical skills is attitude, desire, commitment, and a sense of the value of this rare opportunity.
