Traditional Japanese Roofed Garden Gate Workshops
Traditional Japanese carpentry is an art passed from one generation to the next, and opportunities to study it are few. This September, master craftsman Jay Van Arsdale will lead a rare hands-on workshop in traditional Japanese hand-tool carpentry at the Gresham Japanese Garden in Gresham, Oregon building a roofed entrance gate for their Japanese garden, Tsuru Island. Students will have the chance to practice under the guidance of Jay Arsdale to this centuries-old joinery and timber-framing techniques.
The entrance gate is the final phase of a year-long major renovation of GJG’s Japanese garden called Tsuru Island. Be a part building the most prominent, and the most visible structure of a Japanese garden. GJG and Jay are looking forward to an amazing, jam-packed full of days filled with learning and honing your skills. Help make this roofed garden gate a lasting contribution to Tsuru Island and an unforgettable learning experience for you.
The workshop really begins Friday night with building/design and construction details, and review of tools and techniques. This will allow actual work on the project to begin Saturday.
The two-day workshop will be intensive (Saturday–Sunday, September 19–20), and devoted to developing the fundamental skills required for traditional Japanese joinery. Participants will practice mortise-and-tenon joinery, precision planing, scribing, layout, and the geometric principles that are the foundation of Japanese timber framing—all using traditional Japanese hand tools.
During the remaining three days, participants will apply these skills to construct and install the garden gate, including its traditional roof structure. Every aspect of the project emphasizes accuracy, craftsmanship, and the methods that have been refined in Japan over centuries.
This workshop is designed for intermediate to advanced carpenters who already possess solid woodworking skills and are comfortable working with hand tools. Participants must provide their own Japanese woodworking tools. See below.
Whether your goal is to deepen your understanding of traditional Japanese carpentry, improve your hand-tool skills, or experience building an authentic structure under the guidance of a master craftsman, this workshop offers an exceptional learning experience that is rarely available.
Space is limited to ensure individualized instruction. Questions: Contact Manny Romanzalez, one of Jay’s apprentice’s, founder of Kezurou-kai PDX, (503) 705-4066.

Japanese Joinery Class Tool List:
The Basics
- Safety glasses
- Hearing protection (for any times when we have loud tools on-site)
- Work boots / closed-toe shoes — we request closed-toe shoes to be on the work site for your own safety
Chisels
- 18 to 24 mm (3/4~1″) and 12mm (1/2″) are required but bring other various sizes if you have them; 48 mm (2”) and 3~6mm (1/8″) will be very helpful. Any style of chisel will work; of course Japanese would be best. Bring at least 1 new Japanese chisel
- Hand planes
- Students will get the most from the class if they bring 1 new Japanese smoothing plane at least 50mm wide (with laminated steel chip breaker). 70mm is standard, but a high quality narrower plane can often be gotten for less money. Western planes can be substituted, but less will be learned. To tune up the smoothing plane you also need 1 Japanese scraper plane (tachiganna) any size, but if you have a choice, wide is recommended.
Saws
- 1 medium 270mm Ryoba (double-edged) saw: Also a small saw
- 210mm~240mm crosscut or ryoba for tenon shoulders or a crosscut Dozuki (Japanese Backsaw) will be useful.
- Sharpening Stones
- Japanese water stones required: 1 medium (1000~1200 grit) and 1 finish stone (minimum 4000 grit). Optional: 1 course stone (220~600 grit).
Hammers
- 1 medium size 375~550g & 1 small size 100~250g. These can be any style, but an octagonal head is useful for the small one. Claw hammers are difficult to use.
Miscellaneous
- Pencil, square, 1 straight edge minimum 12” long (beveled is preferred.)
- Sashigane (Japanese carpenter’s square). Any flat square will work
- Shaku (traditional method for measurement)
