Measure the installation space before comparing washing-machine features. In a Japanese apartment, the waterproof pan, tap height, drain position, lid clearance, and door swing can rule out a model before capacity or price matters.
Start with about 1.5 kg of laundry per person per day. Then add capacity for how often you wash and whether you regularly clean sheets or blankets.
The main choice is a top-loader or a drum washer-dryer. Choose a top-loader for lower upfront cost and straightforward maintenance. Choose a drum machine when drying in the same machine is worth the extra size, weight, and cost.
Top-load or drum-type
Japan sells washing machines in two main families: 縦型 (tategata, top-load) and ドラム式 (doramu-shiki, drum-type).
A top-loader fills the tub with more water and moves clothes with a pulsator at the bottom. Cycles are usually shorter, and the lid needs clear space above the machine. Most models rely on line drying or a separate dryer.
A drum machine lifts clothes inside a horizontal drum and drops them through a smaller amount of water. Many Japanese drum models also dry the load. The drying system may use a heat pump or an electric heater, so check the specification instead of assuming every drum model works the same way.
Drying capacity is lower than washing capacity. A machine that washes 7 kg may dry only 3.5 kg. If you expect one-button wash-and-dry cycles, use the drying figure as the real limit.
How much capacity do you need?
Panasonic, Hitachi, Sharp, and AQUA use about 1.5 kg as one person’s laundry for one day. That gives you a useful starting point:
- 1 person: about 1.5 kg per day
- 2 people: about 3 kg per day
- 4 people: about 6 kg per day
Treat this as the daily load, then add room for your routine. Panasonic recommends at least 1 kg of spare capacity for sheets and similar items. A person washing every day can use a smaller machine than someone saving laundry for the weekend.
Measure the delivery route too. A machine can fit the waterproof pan and still fail to pass through the apartment door, hallway, lift, or stairwell.
Three real models to compare
Affiliate disclosure: As an Amazon Associate, I earn from qualifying purchases.
AQUA AQW-S5R: a compact 5 kg top-loader measuring 525 × 500 × 890 mm including the drain hose. It needs a waterproof pan with an internal depth of at least 498 mm. AQUA now marks this model as discontinued, so treat Amazon stock as clearance or remaining inventory. Check the seller, delivery date, warranty, and return conditions before buying. Check the AQUA AQW-S5R on Amazon Japan.
Panasonic NA-FA10H5: a 10 kg top-loader for larger households or batched loads. It measures 599 × 1,024 × 628 mm including hoses and weighs about 40 kg. Panasonic lists 103 L standard water use, 50 Wh energy consumption per rated wash, and 385 W motor power during washing. Those last 2 figures measure different things. Read Panasonic’s specifications, or check the NA-FA10H5 on Amazon Japan.
Sharp ES-S7J-WL: a compact drum washer-dryer with 7 kg washing capacity and 3.5 kg drying capacity. Its full external dimensions are 640 × 600 × 1,039 mm including hoses, and it weighs about 73 kg. The WL version opens to the left. This is a 2023 model rather than Sharp’s current 2026 generation, so compare its old-stock price with newer compact models before deciding. Read Sharp’s specifications, or check the ES-S7J-WL on Amazon Japan.
Measure these before ordering
- The waterproof pan’s internal width and depth
- Tap height and space for the inlet hose
- Drain position and hose route
- Top-loader lid clearance or drum-door swing
- Doorway, hallway, lift, and stair width
- The 100 V outlet and grounding connection
Use the full external dimensions, including hoses. A manufacturer’s body width can be smaller than the installed width.
Door direction matters on a drum machine. Sharp sells the ES-S7J in left-opening and right-opening versions. The door is not designed to be reversed after purchase.
Drying changes the buying decision
A top-loader makes sense when you have balcony space, a bathroom drying system, or room for an indoor rack. It costs less and leaves more of the budget for the fridge, air conditioner, and other move-in expenses.
A drum washer-dryer earns its space when you need reliable drying during rainy season, have limited hanging space, or want laundry finished while you are at work. Check whether the model uses heat-pump or heater drying. Heater models generally use more electricity and can expose clothes to higher temperatures.
Budget for disposal
Washing machines fall under Japan’s Home Appliance Recycling Law. Disposal normally involves 2 separate charges: the manufacturer’s recycling fee and the retailer’s collection and transport fee.
As of April 2026, the official recycling table lists washing-machine fees from ¥2,530 to ¥3,300 depending on the manufacturer. Collection and transport are charged separately by the retailer or local service. Ask for the total removal price when ordering a replacement.
METI explains the process in its Home Appliance Recycling Law guidance. The current manufacturer fees are listed by the Home Appliance Recycling Ticket Center.
When a retailer delivers a new machine, arranging removal at the same time is usually the easiest route. A private second-hand seller does not normally handle your eventual disposal, so keep that future cost in the budget.
Which type should you buy?
One person in a small apartment: start with a compact 5 to 6 kg top-loader. Measure the pan and tap before choosing the model. A discontinued machine can still be reasonable when the price and seller terms make sense.
A couple or small family that can hang laundry: compare 7 to 8 kg top-loaders. Increase the capacity when you batch loads or wash bedding regularly.
A household that needs automatic drying: choose by drying capacity, external dimensions, door direction, and drying method. The wash-capacity number alone will give you the wrong comparison.
If you are equipping an unfurnished apartment, the same measurement problem appears with air conditioners. My guide to buying an air conditioner for a Japanese apartment covers that decision.
Quick questions
Can I use gel-ball detergent pods? Check both the detergent packet and the machine manual. Pod instructions commonly tell you to place the pod in the empty drum before adding clothes. Keep pods out of an automatic liquid-detergent dispenser unless the manufacturer explicitly permits them.
Can I bring a washing machine from another country? Japanese homes use 100 V power, with 50 Hz in eastern Japan and 60 Hz in western Japan. Voltage, frequency, plug, grounding, plumbing, delivery size, and service support all need to match. Buying a Japanese-market machine is usually the safer and cheaper route.
Can I reverse a drum-machine door? Assume the answer is no unless the manual says otherwise. Choose the left-opening or right-opening version before ordering.
The short version
Start with 1.5 kg per person per day, add room for your washing schedule, and measure every part of the installation route. A top-loader suits buyers who can hang laundry and want lower upfront cost. A drum washer-dryer suits buyers who need automatic drying and have enough space for the machine, door, hoses, and delivery route.
