Many people insist on a "south-facing" home when choosing a property, but is a south-facing home really the right fit for everyone? From advantages and drawbacks to comparisons with other directions, this guide explains how to assess sunlight and choose a property with confidence.
What is a south-facing home?
In real estate, the term "orientation" refers to the direction that the balcony or the largest window faces. Because Japan is in the Northern Hemisphere, sunlight comes in from the south, so south-facing properties generally receive longer hours of sun. In apartments and condominiums in particular, south-facing units tend to be more popular and often command higher rent.
What are the benefits of living in a south-facing home?
The room stays bright throughout the year
The biggest advantage is the brightness created by longer hours of sunlight. In winter, the sun sits lower in the sky, allowing more sunlight to enter the room and reducing the need for artificial lighting.
Utility costs can be reduced
Even in winter, sunlight can help warm the interior, so heating use may be reduced, which can help lower utility costs. However, depending on the location and surrounding environment, the expected benefit may not be as strong as anticipated.
Laundry dries more easily and moisture is less likely to build up
Hanging laundry on a south-side balcony can shorten drying time. Good ventilation also helps reduce the risk of mold growth, food spoilage, and health problems caused by damp conditions.
Higher asset value
Popular south-facing properties may be easier to sell at a relatively favorable price. That said, it is important to note that acquisition costs at the time of purchase also tend to be higher.
What are the drawbacks of a south-facing home?
Indoor temperatures rise more easily in summer
Strong daytime sunlight can raise indoor temperatures in summer and increase air-conditioning costs. Measures such as blackout curtains and insulating window film can be effective.
Interior finishes are more likely to fade in sunlight
Walls, floors, and tatami can fade or discolor more easily due to ultraviolet rays, which means there is a risk of significant replacement or repair costs.
In some cases, the orientation can work against you
If there is a road on the south side, you may be unable to open the curtains because of visibility from pedestrians and cars, making it harder to take advantage of the sunlight. In addition, if a tall building stands to the south, sunlight may be significantly reduced.
What are the characteristics of directions other than south?
| Direction | Characteristics | Best suited for |
|---|---|---|
| East-facing | Good sunlight from morning to late morning | Early risers and people who struggle with summer heat |
| West-facing | Good sunlight from afternoon to evening | Night owls and people who struggle with winter cold |
| North-facing | Less sunlight, but cooler in summer | People who prioritize price and those often away during the day |
What should you check when choosing a property with good sunlight?
- Visit the property around midday (11:00 a.m. to 2:00 p.m.) and confirm the actual level of sunlight
- Check the surrounding zoning and understand the future risk of nearby high-rise construction
- Check the floor plan and the location, size, and number of windows
- Check whether the balcony is too deep (if it is too deep, sunlight will not reach the interior)
- Check whether the railing is made of glass (this affects light transmission)
- Consider the floor level of the unit (higher floors generally have a lower risk of obstruction)

Frequently Asked Questions (FAQ)
Q. Which is easier to live in, south-facing or east-facing?
That depends on your lifestyle. If you spend a lot of time at home during the day, a south-facing unit is often more suitable. If you are an early riser and are often out in the afternoon, an east-facing unit may feel more comfortable. East-facing homes also suit people who are sensitive to summer heat.
Q. How much higher is the rent for a south-facing property in practical terms?
In general, for properties with otherwise similar conditions, rent tends to be several thousand yen to around 10,000 yen higher than for north-facing units. However, the difference varies significantly depending on the location, floor, and facilities.
Q. How can you tell when a south-facing property still has poor sunlight?
Four checks are effective: visiting during the daytime, confirming the height of buildings on the south side, checking the depth of the balcony, and reviewing the surrounding zoning. Corner units tend to secure better sunlight because they have windows facing multiple directions.
Q. What kinds of uses are north-facing properties suitable for?
They are well suited to storing books and collections, computer work rooms, and storage spaces, in other words, uses where direct sunlight and temperature changes are best avoided. They also suit people who prefer cooler conditions in summer.
