What's the difference between an "apartment" and a "mansion" in Japan? An easy-to-understand explanation of the advantages and disadvantages for foreigners.
In Japan, the terms "apartment" and "mansion" used for rental properties mainly differ in terms of building structure and cost.
Generally, if you want to keep rent low, you should choose an apartment, but if you prioritize safety and soundproofing, you should choose a condominium.
This article explains the differences between apartments and condominiums, as well as their respective advantages and disadvantages, so please use it as a reference.
1.The difference between an apartment and a condominium
Actually, there is no clear definition that distinguishes between apartments and condominiums.
Apartments and condominiums are distinguished according to the internal regulations of companies that handle properties, such as house builders, real estate companies, and portal sites.
Therefore, even for the same property, the name may differ depending on the company.
The meaning of the name differs between Japan and other countries.
In Japan, the term "mansion" refers to a reinforced concrete apartment building and does not necessarily mean a luxury residence.
It's important to note that this is quite different from the English meaning of "mansion."
Furthermore, the nuance of the word "apartment" in Japan can differ from that of the English word "apartment." In Japan, it is common to refer to small-scale apartment buildings constructed of wood or light steel frames as "apartments."
As you can see, Japanese real estate terminology sometimes has unique meanings, which is one of the points that can easily confuse foreigners.
The main difference is the building structure.
As mentioned earlier, the distinction between apartments and condominiums varies depending on the company, but generally, they are distinguished by the building's structure.
[Examples of distinctions between apartments and condominiums]
| Building structure | scale | |
| apartment | Wooden and light steel frame construction | 2-3 stories |
| apartment | Reinforced concrete construction / Steel-reinforced concrete construction | Three stories or more |
Apartment buildings that are two or three stories high and constructed of wood or light steel frames are often called "apartments," while apartment buildings that are three stories or taller and constructed of reinforced concrete or steel-reinforced concrete are often called "mansions."
Refer to general classification methods, and then make your decision after reviewing the details of each property.
2.Advantages and disadvantages of living in an apartment
As mentioned earlier, the distinction between apartments and condominiums varies from company to company, so here we will define "apartment" as "a building constructed of wood or light steel frame" and explain its advantages and disadvantages.
merit
- Rent tends to be relatively cheaper than that of an apartment.
- Management and repair fees tend to be relatively low.
- Good ventilation (in the case of wooden buildings)
Compared to apartments, the main advantage is that costs are generally lower.
Disadvantages
- Some properties have security and crime prevention concerns.
- Some areas have poor sound insulation.
For those who want to keep costs down as much as possible and aren't too concerned about security or noise from other residents, an "apartment" is a good option.
3.Advantages and disadvantages of living in an apartment
Next, we will define "apartment buildings" as "buildings with a sturdy structure such as steel frame or reinforced concrete," and explain their advantages and disadvantages.
merit
- Excellent earthquake and fire resistance.
- Many properties have excellent security features, such as automatic locks.
- High airtightness
Apartments constructed with steel frames or reinforced concrete offer excellent earthquake and fire resistance.
Furthermore, properties equipped with features such as automatic locks, intercoms with monitors, and security cameras can alleviate security concerns.
Disadvantages
- High rent and management fees.
From a cost perspective, it has more disadvantages than living in an apartment.
Therefore, for those who prioritize security and soundproofing over the associated costs, an apartment building is recommended.
