If you’re apartment hunting in Japan, you’ll quickly come across listings labeled 1R, 1K, 1LDK, etc…

In this article, I’ll clearly explain how Japanese apartment layouts work, what each type means, and how to choose the right one for your lifestyle in Japan.



How Japanese Apartment Layouts Work

Japanese apartments are described using numbers and letters.

The Number

The number shows how many separate rooms there are (not including the kitchen or living space).

The Letters

The letters describe the type of shared area:

  • R = Room

  • K = Kitchen

  • D = Dining

  • L = Living

Once you understand this system, apartment listings become much easier to read.



Common Apartment Types in Japan

〜1R (One Room)〜

A 1R apartment is one room in an open space.Your bed, desk, and kitchen are all in the same room.

  • Usually the cheapest option

  • Very common for students and short-term stays

Best for: solo residents or small budgets


〜1K (One Room + Kitchen)〜

A 1K apartment has one bedroom plus a separate kitchen area.

  • Cooking smells stay out of your bedroom

  • Slightly more expensive than 1R

Best for: solo workers who cook at home


〜1DK (One Room + Dining Kitchen)〜

A 1DK includes a kitchen large enough for a dining area.

  • More space than 1K

  • Good balance between size and price

Best for: people who want a little extra space without a high rent


〜1LDK (One Room + Living / Dining / Kitchen)〜

A 1LDK has a separate bedroom plus a combined living, dining, and kitchen area.

  • Much more comfortable

  • Higher rent, but better long-term living

Best for: couples, remote workers, long-term residents



What Does「帖-Jō」(Tatami Size) Mean?

In Japan, room sizes are often measured in tatami mats which are 「帖-Jō」, for example:

  • 6帖 (roku-jō) = 6 tatami mat sized area

Even if the room has wooden flooring, tatami mats are still used as the standard measurement.



Challenges Foreigners Face When Renting in Japan

Understanding layouts is only one part of renting in Japan. Many foreigners also struggle with:

  • Language barriers

  • Japanese guarantor requirements

  • Complicated contracts

  • Limited listings available to non-Japanese residents

This is why choosing a foreigner-friendly housing service makes a big difference.



How to Find An Apartment in Japan as a Foreigner

If you’re new to Japan or don’t speak Japanese confidently, I recommend using GTN.

They provide:

  • Apartment support specifically for foreign residents

  • No Japanese guarantor required

  • Multilingual assistance

  • Services available nationwide
