When you're house-hunting in Fukuoka and open a property website, you'll see abbreviations such as "1K", "1LDK" and "2DK" everywhere. If you're used to homes described by their number of bedrooms and living rooms, they can be a little baffling at first.
Today, let's decode these layout codes and share a few facts about Japanese building regulations, to help you choose the home that best suits your lifestyle.
1. What do L, D, K and S stand for?
These four letters are the core components of Japanese floor plans:
- L (Living): Living room.
- D (Dining): Dining room.
- K (Kitchen): Kitchen.
- S (Service Room): Service room (in Fukuoka it's usually called a "storage room", nando, 納戸).
💡 Did you know? Why can a room only be labelled "S" when it is clearly a room?
Some properties are listed as "1LDK+S". That S may look like a room, but under Japanese law it cannot be called a habitable room (kyoshitsu, 居室). Under the Building Standards Act, a room used for living in must have windows with an area of at least 1/7 of the floor area. If its light or ventilation falls short of this standard, however large it is, it can only be labelled "S". These rooms are usually used as storage rooms, studies or walk-in wardrobes.
2. How is 1K different from 1R?
This is the question clients ask me most. Although both look like spaces for one person, there is one key structural difference: a door.
- 1R (One Room): The kitchen and the sleeping area are connected, with no partition at all. Walk through the front door and the living area, kitchen and bed are all right there, visible at a glance.
- 1K (1 Kitchen): The kitchen and the room are separated by a solid wall and a door.
The advantages of a 1K are better privacy and more efficient control of heating and cooling costs (you don't have to heat or cool the kitchen and hallway at the same time).
3. Love cooking Chinese food? Then do your best to avoid 1R layouts!
If you plan to stir-fry often at home, fry ginger and garlic, or even make dishes that produce lots of cooking fumes, I strongly recommend you avoid 1R layouts.
The reason is simple: you end up "sharing" the smells and cooking fumes.
1R layouts suit people who don't cook, or who only make simple meals (such as heating things in the microwave or boiling noodles). If you often cook Chinese food, the fatal flaws of a 1R are:
- Fumes everywhere: In a 1R, the kitchen is right next to your bed with no separation at all. Cook one stir-fry and your suits, coats and duvet may smell of that dish for days.
- Noise: The hum of the fridge compressor will be right by your ear in the quiet of the night.
My advice: If you'll be cooking Chinese food at home more than three times a week, choose at least a 1K. That extra door keeps out most of the fumes and smells, protecting your wardrobe and your sleep.
4. 1LDK vs. 2DK: which is better value?
- 1LDK: One spacious room combining the living room, dining area and kitchen (the LDK), plus one separate bedroom. Ideal for singles who value quality of life and like having friends over, or for newly married couples.
- 2DK: Two separate rooms, but a relatively small living/dining area (DK). These properties are usually older but cheaper to rent, and suit budget-conscious tenants who need to sleep in separate rooms or need a separate workspace. (They are also relatively uncommon in Fukuoka.)
Summary
Choosing a home isn't just about whether the floor plan looks good; how the spaces are divided and how you move through them in daily life are what really matter.
