 We introduce reliable HIA building constructors and renovation companies to new home builders/ home renovators with an impartial perspective. And this service is free of charge.

**HIA will stand for Highly Insulated Airtight housing’.**

Service Overview

Japanese houses have the lowest level of insulation and airtightness compared to all other developed countries.
There are very few building companies that perform as well as those in the EU or North America.
When building a home, it is essential to have an HIA home that will keep you and/or your loved ones cool in the summer and warm in the winter.

However, it is difficult for customers to find the right type of housing or remodeling companies.

We will introduce Japan's top-performing companies to help with your home building project.
 
For both new construction and remodeling, we have strict insulation and airtightness partnership standards. Only a few companies with extensive experience meet these standards in insulation and airtight remodeling. We have carefully selected and partnered with these companies.

Why us?

1.

Get help finding a high-performing housing company

New construction home:   earthquake resistance and heat resistance are 1.5 times higher than the Building Standards Law. All of them conduct airtightness measurement tests.
 
As for remodeling projects, we introduce only knowledgeable, reliable, and experienced companies.
Even major housebuilders do not conduct airtightness measurements in their homes and their houses are not well-insulated. There is a small number of Japanese housing companies that build houses with the same level of performance as in Western companies.
When you build your first house, it is very difficult to judge the functional performance of a house.

2.

Reliable employees in charge!

When building a house, finding a person-in-charge of your project is very important.
When contacting a housing company as an individual, one cannot choose whom to work with or for you.
However, Smile Support customers will be prioritized by our partnered housing companies and a most reliable consultant will be assigned to assist each project.

3.

Take advantage of our special offers!

Every housing company that we partnered with have their own special offers such as a 3% discount, complimentary options for spending 500,000 JPY, and more.
When you use Smile Support, a selection of available housing companies will be introduced to build in your planned area along with the benefits that they offer.

Benefits of living in an HIA house

Benefit 1:
​​​​​​​A comfortable home that is warm
in winter and cool in summer

All year-round, the temperature inside the house remains stable regardless of the weather outside because there will be no radiant heat from the wall.
The air conditioning can be set at a mild temperature; especially if you do not like the strong wind from the air conditioner.
Floor heating installation and utility fees can be expensive, but in an HIA house, these fees will not be applied. Imagine walking barefoot in the comfort of your own home during winter without having to pay an expensive heating bill. 
Plus, you'll get better quality sleep, too.

Benefit 2:
​​​​​​​Lower risk of allergies and asthma

HIA houses cause little to no condensation.
This reduces the risk of developing allergies and asthma.
In a low-performance house, condensation between the walls can cause mold and dust mites.
Many people experience a dramatic decrease in allergies, asthma, and other symptoms as soon as they move into an HIA house.

Benefit 3:
​​​​​​​Good insulation and airtightness make housework easier.

100 housewives who live in HIA homes were asked what has changed since living there.

45% of respondents said their utility bills have dropped, and 43% of respondents answered "My household chores have become easier."
For example, when the house is warm on winter mornings, you can get up and start preparing breakfast right away. Also, it does not get cold in winter when you turn on the exhaust fan, so cleaning the bathroom can be done more comfortably.

Benefit 4:
​​​​​​​Lower risk of heat shock

 In Japan, as many as 19,000 people a year die from heat shock that is a shock from the temperature change due to poorly insulated and air sealed housing. This is five to six times higher than the number of people killed in traffic accidents. In other words, staying inside a house is potentially more dangerous than being outside.
Additionally, many people, who survive, end up with illnesses such as paralysis.
An HIA house keeps the entire home at a stable temperature, preventing the risk of getting a heat shock.

Benefit 5:
Free up more storage space

In a typical home, thick winter bedding, heating equipment, etc. take up a lot of storage space. Space should be used as a place to live without having to store bulky furniture and equipment. HIA housing allows more space for you to enjoy. 

Benefit 6:
​​​​​​​Low utility bills and affordable living 

An HIA house is more expensive to build, but the future savings in heating and cooling costs outweigh the costs. When building a home, it is important to think about energy efficiency, just as you would with a car.
 After paying off the loan, all of the savings from utility bills will remain, and you will continue to save.

Supporting newly custom-built HIA houses

We have carefully selected and partnered with some of the top-performing housing companies in Japan. 
These companies build homes that are at least 30% more insulated than the government's insulation performance standards.
These standards are strict and only a few percentages of housing companies in Japan can meet them.
If you are not familiar with insulation and airtightness standards in Japan, finding a company to work with can be difficult. At Smile Support, we carefully select the most suitable housing companies to meet our customers’ needs for free of charge.
