Understanding 1R, 1K, DK, LDK, and Their Differences
When browsing apartment listings in Japan, you’ll often encounter terms like 1R, 1K, 1DK, and 1LDK instead of typical bedroom counts. These abbreviations represent the total number of rooms, excluding the bathroom and toilet. Here’s what each one means and the features to expect.
1K and 2K Apartments
The "K" stands for kitchen, and the number before it indicates how many rooms are included, excluding the kitchen.
- 1K: One room plus a kitchen. A popular, affordable choice for singles.
- 2K: Two rooms plus a kitchen. Great for couples or individuals needing extra space for an office or storage.
1DK and 2DK Apartments
The "D" stands for dining area, and these apartments offer more space than a typical 1K.
- 1DK: One room with a dining area and kitchen. Slightly larger than 1K, ideal for singles needing more living space.
- 2DK: Two rooms with a dining area and kitchen. Suitable for small families or roommates.
1LDK and 2LDK Apartments
The "L" stands for living room, making these apartments more spacious than DK options.
- 1LDK: One room with a living room, dining area, and kitchen. Perfect for singles or couples who prefer more comfort.
- 2LDK: Two rooms with a living room, dining area, and kitchen. An excellent choice for families or those needing extra space for activities.
Before looking for an appartment in Japan

The floor plan displayed above is an example of a 1K apartment layout, commonly found in Japan. This type of apartment consists of one main Room (7.5 Jō), which refers to the size of the room measured in tatami mats. The kitchen area is separate and located near the entrance (Ent.), along with the Shoebox (SB) for storing shoes. The apartment features a compact Powder Room with a Bath and Toilet, offering all necessary amenities in a small space. There is also a storage area (Sto.) next to the kitchen, and the apartment includes a small Balcony that provides outdoor access. This layout is ideal for single occupants, providing a functional and efficient living space.
When navigating Japanese apartment listings, remember that the abbreviations focus on the layout rather than the number of bedrooms. Understanding these terms can help you find the perfect apartment that meets your needs.
