If you’ve ever browsed Japanese property listings and come across terms like 1LDK or 3DK, you’re not alone — these abbreviations can be confusing at first. Here’s a quick guide to help you decode what they mean before your next apartment viewing.
LDK, DK & The Numbers

In Japan, homes and apartments are labeled using a combination of letters and numbers:
- LDK: Living room, Dining area, and Kitchen combined — plus bedrooms.
- DK: Dining area and Kitchen only, with no separate living room.
- The Number (1, 2, 3): Indicates how many bedrooms there are.
Example:
2LDK = 2 bedrooms + living, dining, and kitchen area.
What About “+S”?
Sometimes you’ll see a “+S” in property listings.

S stands for Storage or Service Room — an extra small room that’s often used for storage, a home office, or a walk-in closet.
Example:
2LDK + S = 2 bedrooms + LDK + storage room (too small to be considered a bedroom).
What You Should Know
Japanese apartments are typically smaller than what many expats expect.
Here are a few key points to keep in mind:
- Always check the layout and size (in square meters) rather than just the room count.
- Layout efficiency often matters more than floor area.
- Make sure the space suits your daily habits, furniture, and lifestyle.
