The floor plan (間取り) determines how comfortable you'll be in your condo. This guide explains how to read floor plan drawings, the characteristics of common layout types, and how to choose the right one for your lifestyle.

How to Read a Floor Plan

Japanese floor plans use specific abbreviations: L = Living, D = Dining, K = Kitchen, S = Service room (no window). A "2LDK" means two bedrooms plus a living-dining-kitchen space.

Common Layout Types

1K / 1DK / 1LDK

Ideal for singles or couples. 1K = one room + kitchen; 1LDK = one bedroom + living-dining-kitchen. The larger the LDK, the more spacious it feels.

2LDK

Standard for small families (2–3 people) or couples with a dedicated work-from-home room.

3LDK / 4LDK

Family-sized. 3LDK suits families of 3–4; 4LDK is for larger families or those who need multiple dedicated rooms.

Key Points When Choosing

  • Storage space: Check walk-in closets and built-in storage volume carefully
  • Window placement: Natural light and ventilation depend on window size and direction
  • Toilet separate from bathroom?: Many Japanese buyers prefer separate toilet and bathroom
  • Open vs. closed kitchen: Open kitchen is trendy but may let cooking smells spread

FAQ

Q. What is a "service room" (S)?

A room that doesn't qualify as a "bedroom" under Japanese building standards due to limited window area. Often used as a study, storage room, or hobby room.

Q. What does "walk-through closet" mean?

A closet you can walk through from one room to another. It adds convenience but slightly reduces usable storage depth compared to a standard walk-in closet.
