Build a Japanese Joinery Toolbox (Step-by-Step Guide)
Build a Japanese-style toolbox using wood joinery and dovetail joints — no power tools needed. The dimensions are flexible, so you can adjust the size to fit your own tool collection.
The Appeal of Nail-Free Woodworking: What Is Wood Joinery?
Wood joinery (接手, tsugite) is the Japanese woodworking practice of connecting pieces of wood without nails or metal fasteners. It's a tradition built around longevity — joints can be taken apart and repaired, which means a well-made piece can last for generations.

Step-by-Step Guide: Building the Toolbox
Step 1: Marking Out Your Stock
Refer to your plans, then mark out the side panels, end panels, and bottom panel.
Tools to use: Pencil, Try Square
Helpful addition: Kiridashi Knife — scribing a line with a kiridashi leaves a fine groove that acts as a guide for your saw and chisel, helping you cut and chop more accurately. If you're new to this, mark with a pencil first, then scribe over it with the kiridashi.
Because you'll be cutting with a saw and chiseling from multiple directions, carry your lines around all faces of each board — mark every surface so the line is visible from any angle. For sections you can't reach until a piece is cut, mark them after cutting.
Pro Tip: Mark any waste areas with an X. It's an easy way to avoid cutting on the wrong side of the line.
Marking Out the Dovetail Joints
The end panels and bottom panel are joined with dovetail joints. To mark the angled lines, use the scale on your try square to set the slope. This project uses a 1:4 dovetail ratio. To make it easier to read the marks, work with the proportional equivalent of 2:8 — set your try square to the 20 mm and 80 mm marks, align them with the top edge of the board, and draw the slope line.
Step 2: Cutting the Parts to Size
Cut each piece to size along your marked lines.
Tools to use: Ryoba Saw — crosscut teeth
Helpful addition: 2 Clamps — holding a board by hand while sawing tends to let it shift, making it harder to cut straight. Clamping the stock frees you to focus entirely on the cut and improves accuracy.
Pro Tip: Account for the saw's kerf. Keep the marking line visible by cutting on the waste side — saw just to the outside of the line, not through it.

Before cutting the joinery sections, lay all the parts out in their final positions to confirm the overall dimensions and decide which boards mate with which. Mark each joint location so you can keep track of which pieces go together. Pay particular attention to the bottom panel — if you flip it over, the dovetails won't fit.
Step 3: Cutting the Joinery — Sawing
Tools to use: Ryoba Saw — rip-cut and crosscut teeth
Saw a relief cut at each end of the sections you'll be carving out with a chisel. Cut the corner waste pieces from the side (crosscut direction). Take care with the final cuts to avoid cutting past your line.

Pro Tip: Cutting the Dovetail Sections
When cutting on a flat surface, tilt your line of sight and the saw to match the dovetail angle. Watch both the top face and the side face as you cut — check that the saw blade stays on the marking line on both faces as you work through the cut.
Step 4: Cutting the Joinery — Chiseling
Chop out the sawn sections with a chisel.
Tools to use: Genno Hammer, Oire Nomi Chisels — for this project, two chisels were used: a 9 mm (slightly narrower than the board thickness) and a 24 mm (slightly narrower than the width being worked).
Helpful addition: Clamps, Kiridashi Knife — the kiridashi is handy for cleaning up corners the chisel can't quite reach.

Step 5: Assembly
Fit the boards together, aligning them to your marks.
Tools to use: Wooden Mallet, Oire Nomi Chisels
Because the dovetail joints can only be inserted from one direction, start by assembling the end panels and bottom panel. If the joint is tight, pare it back gradually with the chisel until it fits. Once the fit feels right, drive it home with the mallet — use a scrap piece of wood as a buffer block to protect the surface and spread the force evenly.
Assemble the side panels in the same way.
Step 6: Attaching the Handles and Lid Retainer
Attach the handles and lid retainer to the assembled box.
Cutting to Fit the Box
Hold the handle and lid retainer stock against the box, mark a line to length, and cut with a saw.
Tools to use: Try Square, Pencil, Saw
Securing with Wooden Nails
There are plenty of ways to fasten parts together — screws, nails, adhesive — but this project uses Wooden Nails.
The handles are secured with two wooden nails each on the inside of the joinery; the lid retainer gets two dowels per side panel, for eight in total.
Tools to use: Try Square, Pencil, Clamps, Wooden Mallet, Gimlet, Flush Cut Saw.
1. Temporary fixation
Measure and mark the Wooden Nail positions against the box. Apply a thin coat of wood glue to the mating face, clamp the piece in place so it can't shift, and tap with the mallet to fine-tune the position.
2. Drilling the pilot holes
Using a gimlet or similar tool, bore a hole at each mark, deep enough for a Wooden Nail to pass through the part and into the box body.
3. Driving the Wooden Nails.
Apply a little wood glue to the tip of each Wooden Nail, insert it into the hole, and drive it in with the mallet. Wipe away any glue squeeze-out.
4. Trimming flush
Trim the protruding end of each Wooden Nail flush with the surface using a flush-cut saw — hold the saw flat against the surface as you cut.
Pro Tip:
After assembly, the lid retainer area may have a small step or mismatch where the joints meet. If that happens, plane down the high spot to get a flat surface — the lid retainer will then sit flush with no gaps.
Step 7: Making the Lid
Cutting the lid to match the inside dimensions of the box gives you a precise fit.
Cut the width to match the box opening and the length to your measurements.
Tools to use: Try Square, Pencil, Ryoba Saw, Plane
1. Mark the lines
Hold the lid panel against the inside of the box and mark it. Measuring the interior dimensions with a try square beforehand will give you a more accurate result. Draw the lines with the try square.
2. Cut
Cut along the marked lines with the saw.
3. Fine-tune
Check that the lid fits the box. If it's tight, pare it back with the plane until it slides in smoothly.
Attaching the Handles
1. Cut
Cut the handle stock to fit the box.
2. Handle 1
The first handle goes where the lid opens. Slide the lid panel fully in, then hold the handle up against the side of the lid retainer. Mark the handle position so its center aligns with the box. Glue it in place at that mark. Let the glue set before moving on — shifting it before it dries will throw off the alignment.
3. Handle 2
The second handle goes at the position where the lid closes. Insert the lid and center it. Hold the handle against the lid retainer in the same way, mark the position, and glue it in place. Resting the lid on top of the box to check the center before gluing gives you a more accurate placement.
Step 8: Finishing
Finish the box to your liking — chamfer the edges with the plane, apply a coat of finish.
