Living in a Japanese-Style Room: Tatami, Futon, Shoji and Upkeep

Quick answer

If your new apartment has a washitsu (Japanese-style room), the three things you'll live with every day are tatami mats on the floor, a futon you lay out and put away, and paper sliding doors called shoji and fusuma. None of them are hard to care for once someone shows you how, and that is exactly what I'm here for.

The short version: vacuum tatami gently along the grain, air your futon regularly so moisture doesn't build up underneath, and slide the doors with two hands so the paper and frames last. Do those three habits and your room stays fresh, dry and pleasant all year.

Caring for your tatami mats

Tatami is a woven rush-grass surface over a firm core, and it has a direction to it, a bit like the pile of a carpet. When you vacuum or wipe, always move along the grain rather than across it, so you don't fray the woven surface. A dry cloth or a lightly wrung-out one is enough for wiping; soaking tatami is the one thing to avoid.

Because it's a natural material, tatami likes air and dislikes trapped damp. Try not to leave rugs, boxes or a mattress sitting in the same spot for months, since that's where discolouration and mould tend to start. On a dry, sunny day, opening the windows for a while does the room a lot of good.

If you spill something, blot it up straight away rather than rubbing it in, then let the area dry. Heavy furniture can leave dents, so felt pads or small coasters under the legs help spread the weight. New tatami has a lovely green colour and grassy smell that mellows to gold over time, which is completely normal, not a sign of damage.

Airing and storing your futon

A futon is meant to be laid out at night and put away in the morning, and that daily rhythm is what keeps it healthy. Overnight your body releases moisture, which sinks into the futon and the tatami beneath it. If you leave the futon flat on the floor all day, that damp has nowhere to go, and over weeks it can lead to mould on the underside.

The simplest fix is to fold or hang the futon each morning so air reaches both sides. Folding it back over itself, draping it over a chair, or hanging it on a balcony rail on a clear day all work well. Many people give it a good airing in the sun once or twice a week, then bring it in before evening damp returns. A futon dryer or a fan pointed at it does the job on rainy stretches.

When you store bedding, use the oshiire (the built-in closet) but don't cram it in tight against the back wall. Leaving a little gap for air, and using a slatted board or a moisture-absorbing sheet on the closet floor, keeps everything dry. If you ever notice a musty smell, that's your cue to air things out sooner and more often.

Handling shoji and fusuma sliding doors

Two kinds of sliding panels are common in a washitsu. Shoji are the light lattice screens covered in translucent white paper that let soft light through, and fusuma are the solid opaque panels, often covered in thicker paper, that divide rooms or close off a closet. Both slide in wooden grooves rather than swinging on hinges.

The trick is to slide them gently and straight, ideally guiding with two hands near the edge rather than yanking one corner. If a door starts to stick, it's usually dust or grit in the bottom groove; a quick vacuum along the track, and sometimes a tiny rub of dry soap or candle wax on the rail, gets things gliding again. Never force a stuck panel, as that's how frames get bent.

The paper is delicate, so keep sharp corners, curious pets and swinging bags away from it. Small tears can be patched, and worn shoji paper can be replaced, but that's usually a landlord conversation, so check your contract before doing any repapering yourself. Day to day, a soft dry brush or cloth is all the cleaning the paper needs.

Everyday habits that keep the room fresh

Most of the work is really just airflow and a light touch. Opening a window or the closet door for a while, not leaving wet laundry drying in a closed room, and wiping up spills quickly will prevent almost every problem before it starts. Slippers or bare feet on tatami are kinder to it than hard-soled shoes or heels.

Ventilation matters most through Japan's humid months, roughly the early-summer rainy weeks and the sticky height of summer. On damp days, running the air conditioner's dry mode or a small dehumidifier keeps the room comfortable and protects both the tatami and your stored futon from moisture without any fuss.

Small problems and easy fixes

If you spot a few dark specks on the tatami or futon, don't panic; catch it early and it's manageable. Wipe the tatami with a cloth dampened in diluted rubbing alcohol and let it dry fully, and give the futon a thorough airing in the sun. Then look at why the damp built up, usually not enough airflow, and adjust the routine so it doesn't come back.

For dents, scratches or a torn screen you inherited, take a photo when you move in and keep it. That way there's no confusion later about what was already there, and if something genuinely needs professional repair you and your landlord can sort it out from a clear starting point.

Settling in feels easier when you're connected

Half of getting comfortable in a washitsu is looking things up in the moment, the best way to fold a futon, a video on re-papering shoji, or ordering a moisture sheet, a futon-airing bag or a dehumidifier to your door. All of that lives on your phone, so having a Japanese number and mobile data sorted early makes the whole settling-in process smoother.

When you're ready, getting connected is quick. The contract needs your residence card, which is issued after you land in Japan, so you sign up once you've arrived rather than before. From there an eSIM can activate the same day in around fifteen minutes, with no store visit, so you can be online in your new room the day you move in. I'll be right here to help you feel at home.
