Shoji Screen Repair and Replacement: DIY Guide for Japanese Homes
Shoji screens (u969cu5b50) are one of the most beautiful u2014 and most fragile u2014 features of a traditional Japanese rental property. The translucent washi paper stretched over a wooden grid allows soft, diffused light to flow through while providing privacy, but it tears easily and deteriorates over time. Replacing shoji paper is one of the most satisfying DIY repairs you can do: the transformation from torn, yellowed paper to fresh white is dramatic, and the materials are inexpensive. I usually do all shoji in a unit between tenants u2014 it takes about half a day and costs under 5,000 yen for an average room.

A shoji screen consists of a wooden lattice frame (u7d44u5b50) typically made from hinoki or sugi, with paper (u969cu5b50u7d19) adhered to one face. Traditional shoji use hand-made washi paper that is thick, strong, and lets through warm light. Modern rental properties often use machine-made paper (u969cu5b50u7d19) or plastic-reinforced shoji paper (u30d7u30e9u30b9u30c1u30c3u30afu548cu7d19) u2014 the latter is more tear-resistant and practical for properties with children or pets.
Paper is attached to the lattice with a thin glue layer and can be removed by wetting with water (traditional) or by applying a spray remover (u969cu5b50u7d19u306fu304cu3057u30b9u30d7u30ecu30fc). The wooden frame rarely needs replacement unless joints have cracked or split u2014 in most cases, only the paper needs attention.

Complete Home Repair Tool Set
A complete kit beats buying individual tools every time u2014 cheaper and always ready.
- Shoji paper (u969cu5b50u7d19) u2014 sold in rolls at Cainz and Konan; standard width is 94 cm for most screens
- Shoji glue (u969cu5b50u7cca) or double-sided shoji tape (u4e21u9762u30c6u30fcu30d7u30bfu30a4u30d7) for beginners
- Spray bottle filled with water
- Smoothing brush (u5237u6bdb) or wide paintbrush
- Utility knife and metal straightedge
- Sponge
- Flat work surface larger than the screen
For beginners, I strongly recommend the double-sided adhesive tape method (u30c6u30fcu30d7u5f0fu969cu5b50u7d19) u2014 it’s sold as an all-in-one kit at Cainz with pre-cut tape strips. It’s faster and more forgiving than traditional paste.
Step-by-Step: Removing Old Paper
Lay the shoji screen flat on the floor or a large table with the paper side up. Wet the paper thoroughly using a spray bottle u2014 work in sections, keeping the paper uniformly damp. Let the water soak in for two to three minutes; the glue will soften and the paper will begin to lift. Peel the paper back slowly from one corner, rewetting any stubborn spots. Traditional washi comes off in one or two large pieces; older plastic-reinforced paper may tear into strips.
Once the paper is off, use a damp sponge to scrub away any remaining glue residue from the lattice strips. Let the frame dry completely before applying new paper u2014 at least two hours in warm weather, longer in humid conditions. A hair dryer on low heat speeds this up considerably.

Adhesives & Sealants
Keep a stock of these u2014 you’ll use them on every single repair job.
Using the paste method: mix shoji paste to a smooth, thin consistency and apply it with a brush to every lattice strip surface that will contact the paper u2014 a thin, even coat is better than thick blobs. Unroll the paper starting from the top of the screen, pressing it gently onto the glued lattice as you go. Work the paper downward, smoothing out bubbles as you go with a dry brush or your palm. Don’t press the paper onto any sections you haven’t glued yet u2014 keep tension as you unroll. Once the full screen is covered, trim the excess paper at the edges with a utility knife guided by a metal straightedge.
Using the tape method: apply the double-sided tape strips to the lattice, remove the backing paper, then press the shoji paper onto the tape. The process is similar but faster and more forgiving of alignment errors. Once the paper is applied, use a heat gun or hair dryer on low heat held 20 cm from the paper u2014 this causes it to tighten slightly across the frame, removing small wrinkles and leaving a drum-tight, professional finish. Trim the edges cleanly.
Repairing Small Tears Without Full Replacement
For small tears or holes in otherwise good shoji paper u2014 especially common from tenant damage mid-tenancy u2014 patch kits (u969cu5b50u7d19u88dcu4feeu30b7u30fcu30eb) are available at Cainz. These are self-adhesive patches of matching shoji paper in standard patterns. Clean the area around the tear, press the patch over it from the front, and smooth out any bubbles. For a nearly invisible repair, cut the patch in a decorative shape (plum blossom, diamond) rather than a rectangle u2014 the deliberate shape looks intentional rather than patched.
Wooden frame repairs u2014 split joints, warped rails u2014 require wood glue (u6728u5de5u7528u30dcu30f3u30c9) and clamps. Remove the paper first, apply glue to the joint, clamp or tape firmly overnight, then re-paper once the glue has fully cured. Severely warped frames from moisture exposure may need to be soaked in water and clamped flat to reshapen before gluing u2014 a time-consuming but effective technique.
