Rooms — 部屋 (Heya)
Japanese homes may be smaller than Western ones, but they use space efficiently. Some rooms serve multiple purposes throughout the day, which is reflected in the vocabulary.
The 玄関 (genkan) is a uniquely Japanese feature -- a sunken entryway where you remove your shoes before stepping up into the home. Every Japanese home and many businesses have one. Always take off your shoes at the genkan.
Traditional Elements — 和の要素

Furniture and Items — 家具 (Kagu)
Modern Japanese homes use a mix of traditional and Western furniture. Many furniture words in Japanese are borrowed from English, making them easier to remember.
Many modern furniture words are katakana loan words from English: テーブル (table), ベッド (bed), ソファ (sofa). If you know English, you already know these words -- just adjust to Japanese pronunciation.
The LDK System
Japanese real estate uses a unique classification system that you need to understand when apartment hunting:
- 1R — One room (ワンルーム), a single open space
- 1K — One room + separate kitchen
- 1DK — One room + dining-kitchen area
- 1LDK — One room + living-dining-kitchen
- 2LDK — Two rooms + living-dining-kitchen
- 3LDK — Three rooms + living-dining-kitchen (common family size)
Room sizes are measured in 畳 (jō), the number of tatami mats. A standard tatami mat is roughly 1.62 square meters, so a 6-jō room is about 10 square meters. This measurement system is used even in rooms that have hardwood floors instead of actual tatami.
Frequently Asked Questions
What does LDK mean in Japanese apartments?
LDK stands for Living, Dining, Kitchen. Japanese real estate uses this system to describe apartments: 1K means one room plus a kitchen, 1DK means one room plus a dining-kitchen area, and 1LDK means one room plus a combined living-dining-kitchen. A 2LDK has two rooms plus the LDK area.
What is the difference between a futon and a Western bed in Japan?
A 布団 (futon) is a foldable mattress placed directly on tatami floors at night and stored in the 押入れ (oshiire) closet during the day. A Western-style bed (ベッド, beddo) stays in place permanently. Many modern Japanese apartments have Western beds, but futons are still widely used.
What is tatami and how is room size measured with it?
畳 (tatami) mats are traditional woven rush floor coverings. Room sizes in Japan are often measured in 畳 (jō) -- the number of tatami mats that would cover the floor. A 6-jō room (about 10 square meters) is a standard bedroom size. A 4.5-jō room is small, while 8-jō or more is spacious.
How do you count rooms in Japanese?
The counter for rooms is 部屋 (heya), but when counting you use the generic counter: 一部屋 (hito heya, one room), 二部屋 (futa heya, two rooms). In real estate, rooms are simply expressed as a number: 1K, 2DK, 3LDK, and so on.
Why do Japanese homes have a separate room for the toilet?
In traditional Japanese home design, the お風呂 (ofuro) bathing area and the トイレ (toire) toilet are separate rooms for hygiene reasons. The bath is for soaking and relaxation, so keeping the toilet separate is considered cleaner. Many modern apartments maintain this separation.
