Recommended Rental Layouts by Household Type: How to Choose for Solo and Two-Person Living

Last updated: About 2 min read

When searching for a rental property, the most suitable floor plan varies significantly depending on your household size. The right type of property for a person living alone differs from what works best for a couple or a family, so it is important to organize this information in advance. In this article, we explain recommended floor plans by household type and typical rent ranges by region.

The most suitable floor plan for living alone is a compact 1K or 1DK that does not leave unnecessary space unused. An overly large room raises the rent and often creates inefficient daily living flow.

Why you should choose a layout without wasted space

A room that does not feel cramped even after placing a desk and a bed is a key point for comfortable living. It is understandable to care about interior design, but it is important to keep in mind that a room without unnecessary space is often easier to live in.

Regional floor plans and rent ranges for solo living

Chugoku/Shikoku1K・1LDKJPY 40,000 to 50,000
Kyushu/Okinawa1K・1LDKAround JPY 70,000

Typical rent levels vary by region, but 1K〜1LDK is the mainstream layout across Japan. The room orientation and whether the unit is a corner room are also important factors that affect comfort.

If two people are starting to live together due to cohabitation or marriage, a 1LDK or a property with 2LDK or more is the standard choice. Many 1K properties are set up for single occupants, and cases where two-person occupancy is not allowed are not uncommon.

Why 1K is not suitable for two-person living

1K is basically a property designed for a single occupant, so in some cases two-person occupancy is not permitted from the outset. If two people plan to start living together partway through a tenancy, confirmation with the landlord or management company is essential. If you are moving because of cohabitation or marriage, choose a 1LDK to 2LDK layout from the beginning.

Properties for two-person living offer a wide range of layouts, and choosing with your future life plan in mind is important. In some areas, detached rental houses are also available, making them worth considering for longer-term residence.

Frequently Asked Questions (FAQ)

What is the most common floor plan for solo living?

Across Japan, 1K〜1LDK is the mainstream choice. There are slight regional differences, but in almost every area this layout accounts for the majority of properties intended for people living alone.

Can two people live in a 1K unit?

Some properties prohibit two-person occupancy. You should first confirm with the management company or landlord. In general, properties with a 1LDK layout or larger are more suitable for two people.

How should you respond if your household size changes?

If your household changes, such as when a child is born, consider moving to a 2LDK to 3LDK or larger layout so that a child’s room can be secured. Choosing a property with your future life plan in mind is important.

Why does comfort differ even with the same floor plan?

It can vary greatly depending on factors such as orientation (for example, south-facing or north-facing), floor level, whether the unit is a corner room, and the surrounding environment. During a viewing, be sure to check sunlight and noise levels as well.
