Learn to make the Koshikake Aritsugi, a complex joint used in house and temple building.

In this course, students will acquire the skills to make more complex joinery work seen in Japanese temples. Students will learn to cut a type of splicing joint called Koshikake Ari Tsugi, or stepped dovetail splicing joint. Splicing joints connect two pieces of timber end-to-end.

Is this course for me?

As this is an advanced course, there are prerequisite skills required. If you have taken the Shokunin Advanced Course, then this is a natural progression for you. For advanced hobbyists / craftsmen / tradesmen, you’ll need to own and know how to use a saw and chisel. You’ll be required to bring along your own chisels and sharpening stone/s for use during the course.

What you will learn:

  • Learn about the Koshikake Ari Tsugi. Understand its structure, function and applications.

  • Learn to layout and cut joints on stock of larger dimensions. Handling larger stock requires slightly different techniques and approaches. One example is employing the centre line marking system used by Japanese carpenters. Learn how to mark accurately for joinery. A pencil line makes a big difference between an ill or great fitting joint!

  • Develop advance psycho-motor carpentry skills. You will develop the hand skills of using the saw and chisel for joinery. You will learn not only how to cut well-fitted joints by hand, but how to do so with speed and efficiency characteristic of the shokunin, all the while maintaining high levels of precision.

Used to join two square sections of timber end to end, the Koshikakke Ari Tsugi is one of the joinery techniques that the Suikoushya carpenters use most often due to its strength and aesthetics.
