What is a 1LDK Apartment? – Real Estate Japan’s Word of the Day


  • A 1LDK is an apartment with one room in addition to a living, dining and kitchen area.
  • L stands for “Living”, D stands for “Dining”, K stands for Kitchen”. The number 1 indicates that there is one room in addition to the main living area.
  • In Japan, the layout of an apartment is described in terms of how many rooms there are in addition to the main living/dining/kitchen area, not the in terms of the number of bedrooms.
  • A 1LDK equivalent to a one-bedroom apartment.
  • A 1SLDK is a 1LDK with an extra room (a “storage” room or “service” room) that does not officially qualify as a bedroom because it may lack a window, for example.
  • 1LDK apartments usually have between 25-sqm and 35-sqm of floor space but can be bigger in the case of higher-end apartments.
  • The cost of a 1LDK can vary widely depending on where it is located, the floor size, the year it was built, and the floor number, in addition to many other factors, but typically in Tokyo’s 23 wards, you should expect to pay minimum monthly rent of about ¥120,000 ($1,100) for a 1LDK.
