How to Wash a Japanese Futon at a Tokyo Coin Laundry: Complete Guide

Japanese futons (futon, 布団) are the traditional bedding used by millions of households in Japan and increasingly by international residents living in apartments without conventional beds. Unlike Western mattresses, futons can — and should — be washed. They absorb sweat, dust, and dust mites over months of use, and a regular wash keeps them sleeping fresh.

The challenge: Japanese washing machines at home are too small for futons. Hand-washing is impractical. The solution is the local coin laundry, which has 22kg+ machines specifically designed for futons.

What Counts as a “Futon” for Washing Purposes

For coin laundry purposes, “futon” includes:

• Shikifuton (敷布団) — The bottom mattress part you sleep on
• Kakefuton (掛布団) — The top blanket / comforter
• Futon covers — Removable outer fabric (these can also be washed in standard machines)
• Pillows — Most can be washed in coin laundry machines
• Light blankets / bedding — Can use a 14kg machine if 22kg is unavailable

Note: Down futons (羽毛布団 / hane-buton) can be washed but require care — see the section below.

Which Machine to Use

Coin laundries in Tokyo have several machine sizes. For futons:

Look for machines labeled 「ふとん」(futon) on the door or controls. Most major chains have at least 1–2 of these per location.

Use our ward directory to find laundromats with futon-capable machines — every entry indicates whether futon washing is supported.

Pricing

Futon washing in Tokyo costs more than standard wash:

• Wash only: ¥1,000–1,500 per cycle (≈ $7–10 USD)
• Drying: ¥600–1,000 (¥100 per 10 min, takes 60–90 min for full futon)
• Total: ¥1,600–2,500 ($11–17) per futon

For a typical Japanese household, washing all futons (2 per person) costs about ¥4,000–5,000 ($28–35) per wash. Most households do this 2–3 times per year — spring (after winter accumulation) and autumn (before winter use).

Step-by-Step: How to Wash a Futon

Step 1: Prepare the Futon

• Remove the futon cover (washes separately)
• Beat or shake out loose dust (do this outside if possible)
• Inspect for major stains — pre-treat at home with a laundry stain stick
• Roll or fold the futon loosely to fit the machine

Step 2: At the Coin Laundry, Choose the Right Machine

• Look for the largest machine, marked 「ふとん」 or with a futon icon
• Open the door and verify the previous user’s items are removed
• Place the futon in the drum — push it inside, don’t try to spread it out

Step 3: Don’t Overload

• One adult futon should fill 60–70% of a 22kg machine’s drum
• If the futon is squeezed in tight, the machine won’t clean it well
• Two single futons may fit a 27kg machine if loosely arranged

Step 4: Insert Payment and Start

• Insert ¥1,000 bill or coins (or IC card)
• Select the futon cycle if there’s a specific button
• Press start (スタート)

The wash cycle takes 45–60 minutes for a futon machine.

Step 5: Wait for the Cycle

• Most laundromats have seating and vending machines
• You can leave and come back, but set a timer
• Don’t leave for more than 60 minutes after cycle ends — etiquette violation

Step 6: Transfer to Dryer

• Open the washer and remove the futon (it’ll be heavy and damp)
• Use the dryer immediately — DO NOT let a wet futon sit (mold risk)
• Put it in a large dryer (matching capacity)
• Drying takes 60–90 minutes total
• Stop the dryer every 30 minutes to redistribute the futon — this prevents lumps

Step 7: Make Sure It’s Fully Dry

This is the most important step. Wet futons grow mold. Test:

• Press your hand into the futon — it should feel warm and dry, not damp or cool
• Squeeze the inside (between layers) — no moisture should come out
• Sniff — should smell fresh, not musty

If unsure, run another 10–20 minutes of dryer time.

Down Futon Special Considerations

Down futons (羽毛布団) can be washed but require extra care:

• Use the “delicate” or “wool” cycle if available
• Shake out and redistribute every 20 minutes during drying
• Drying may take 90+ minutes — be patient
• Place 2–3 clean tennis balls in the dryer to break up clumps (some laundromats provide these)
• If clumps form, you can manually break them up after drying

Common Mistakes to Avoid

Mistake 1: Using a too-small machine

The futon won’t actually clean. The water can’t circulate properly, and you’ll have wet patches and uneven cleaning. Always use the largest machine available.

Mistake 2: Not drying long enough

This is the #1 cause of mold and odor. Better to over-dry than under-dry.

Mistake 3: Washing during high-pollen seasons (spring)

If you have allergies, drying outdoors after coin laundry use can re-collect pollen. The dryer is your friend year-round.

Mistake 4: Trying to wash old or fragile futons

Very old futons may fall apart in industrial machines. If yours is 5+ years old and showing wear, consider replacing rather than washing.

Mistake 5: Mixing futons with regular clothes

The futon needs its own cycle. Don’t add clothes — they’ll get lost in the bulk.

How Often to Wash

• Light use (well-aired daily): 2x per year
• Heavy use or sweat-prone sleeper: 3–4x per year
• After illness: Wash promptly
• For dust mite allergies: Wash every 2–3 months

Alternative: Professional Futon Cleaning Services

If you don’t want to handle it yourself, services like Lenet, Whasee, and similar offer pickup-and-deliver futon cleaning for ¥3,000–5,000 per futon. This includes professional sterilization. The trade-off is 1-week turnaround vs. 2 hours at the coin laundry.
