Renting a Family Apartment in Tokyo: Sizes, Rent and What to Expect

Published September 8, 2026 | Kurabeel

Searching for a family apartment in Tokyo is a different exercise from searching for a single room. The listing codes are the same, but the number of rooms tells you almost nothing about whether a family of four will fit, and the things that decide whether you enjoy living there — construction, floor, neighbours — are buried in fields most people skip. Here is what to read first.

What size do you actually need? Read the square metres, not the room count

Japanese listings use codes like 2LDK and 3LDK, where the number is the count of bedrooms and LDK is the combined living, dining and kitchen space (full explanation of the codes). The trap is that two apartments can both be 2LDK and differ by 20 square metres.

For reference, a typical American three-bedroom apartment is 110–140 m². A Tokyo 3LDK at 75 m² is a normal family home here. Storage is the part that surprises people most: closets are shallow, and there is rarely a basement, garage or attic.

What does it cost per month? Rent by area

These are broad ranges, and age of the building moves them as much as the ward does. The useful pattern for families: moving one or two stations further out usually saves more than giving up a room, because rent falls with distance from the terminal station faster than it falls with floor area (ward-by-ward figures).

Why does construction matter more than the floor plan?

Because children make impact noise, and impact noise is a construction problem. Look for the structure field in the listing:

Rugs and mats help a little; they do not fix a wooden floor slab. If you have small children, choosing RC and losing five square metres is the better trade. Noise complaints are the single most common source of trouble for families renting in Japan.

Ground floor or higher up?

• Ground floor — no household below you, so footsteps stop being a daily worry. Easier with strollers and bicycles. Usually slightly cheaper. Weaker on security, sunlight and damp.
• Upper floors — better light, better security, better views. But you will be managing noise, and you will be carrying a stroller and a child up whenever the elevator is full or absent.

If you take a ground-floor unit, check for window grilles and a secondary lock, and check whether the room is visible from the walkway. If you take an upper floor, budget for floor mats from day one.

What is not included? More than you expect

• Light fixtures — most rooms have only a ceiling socket. You buy the lamps.
• Curtains and rails — not provided, and Japanese window sizes are non-standard, so measure before buying.
• Air conditioning in every room — often only the living room has a unit. Extra units cost ¥70,000–120,000 installed.
• Oven and dishwasher — rare. Most kitchens have a two- or three-burner gas hob and a fish grill.
• Washing machine — you buy it. Check where the drain and the machine space are; the balcony is common.

For a family, expect ¥200,000–500,000 to make an empty apartment liveable, separate from the move-in costs (detailed furnishing costs).

What families should tell the agent up front

Many buildings set a maximum number of occupants, and children count. Some buildings are built for single tenants and will not accept a family at all. None of this appears reliably in the listing. Say at the start: how many adults and children, the ages of the children, your move-in month, and your one non-negotiable condition. That single message removes every apartment you would have been refused later.

Frequently asked questions

What size apartment does a family need in Tokyo?
A couple with one young child fits comfortably in a 2LDK of 50 to 60 square metres. Two children, or one child of school age who needs a room, usually means a 3LDK of 65 to 85 square metres. Japanese family apartments are smaller than their equivalents in North America or Europe, so compare the square metre figure in the listing rather than the number of rooms.

How much does a family apartment in Tokyo cost per month?
A 2LDK runs roughly 200,000 to 350,000 yen a month in the central wards, 110,000 to 170,000 yen in outer residential wards such as Setagaya or Suginami, and 85,000 to 130,000 yen in the suburbs and neighbouring prefectures. A 3LDK typically adds 20 to 40 percent. Moving one or two stations further from the terminus often saves more than dropping a room.

Does building construction matter when you have children?
It matters more than the floor plan. Reinforced concrete buildings, listed as RC, transmit far less impact noise than wooden or light steel construction, and impact noise is exactly what children produce. Look for RC or SRC in the structure field of the listing. If you cannot get it, the ground floor is the next best option because there is no household below you.

What is not included in a Japanese family apartment?
Light fixtures, curtains and curtain rails are usually not provided, and neither are ovens, dishwashers or a washing machine. Air conditioning is often installed only in the living room, so each additional unit is your cost. Budget 200,000 to 500,000 yen for a family to make an empty apartment liveable, on top of the move-in costs.

In short

• Compare square metres, not room counts — 2LDKs vary by 20 m²
• One or two stations further out saves more than dropping a room
• RC construction beats a better floor plan when you have small children
• Lights, curtains, extra air conditioners and appliances are your cost
• State the number and ages of children up front — occupancy limits are real
