It seems that mid- to high-end housing manufacturers are declining, while low-cost condominium developers are thriving.

There was an interesting article in the Nikkei newspaper.
It showed the change in the number of units sold for the top 10 best-selling properties between 2005 and 2011.
It's a graph, so it's just a rough reading.
From 1st place, left: 2005; right: 2011.
Let's try displaying it with.
1st place: Sekisui House 2.1 1.7
2nd place: Sekisui Heim 1.2 1.1
3rd place: Tama Home 0.5 1.0
4th place: Daiwa House 1.2 1.0
5th place Hebel 1.2 1.0
6th place: Misawa Homes 1.3 0.9
7th place: Sumitomo Forestry 1.0 0.9
8th place Ichijo Construction Company 0.7 0.9
9th place - Construction 0.7 0.8
10th place: Ernest One 0.4 0.7
One thing is clear at a glance when you look at the graph.
This is because all of the top mid- to high-end manufacturers have gone down.
It is said that Tama Homes, a developer of low-cost housing, is making great strides.
It's polarization.
The only exception is Ichijo Komuten.
It can be seen that it is the only national manufacturer to have made significant progress.
In addition to being the best insulated and energy-efficient among manufacturers, it is also inexpensive.
This means that consumers have understood this.
Housing manufacturers and the government tend to overlook insulation, but the public is more aware of its importance.
It may be that you understand.
Ichikensetsu and Ernest One are condominium developers, and they have built 100 buildings in many prefectures.
This is a company that has built the above (over 1,000 buildings in the metropolitan area).
In Japan's largest commuter town, Saitama, the No. 1 company has over 2,000 buildings in just one prefecture.
However, in small prefectures like Tottori and Saga, the number of buildings in first place is either more than 100 or less.
That is the situation.
The criteria for determining whether a home builder is a builder are those who build more than 150 homes per year.
We are trying to bring the standard up to the top runner standard.
Ernest Wang is one of those people, and he plans to achieve this goal within fiscal year 2013.
This is the purpose of this standard. This means that the start of this standard is just six months away.
I believe that the minimum standard for achieving energy conservation, health, and economic efficiency is the top runner standard in the region.
I think so. It is definitely not the next generation energy conservation standard.
I don't know how many companies across the country have more than 150 buildings, but the houses built by these companies are as follows:
It is much cheaper than the mid-range and high-end houses of major manufacturers. However, those companies are not as good as their local competitors.
In some ways, their impact on specification standards may be greater than that of home builders.
If we continue like this, an interesting phenomenon will occur.
If housing manufacturers continue to not improve their insulation specifications,
In fiscal year 2014, all major housing manufacturers except Ichijo Komuten and Sweden House
This will fall below the specifications of the "cheap" developers.
It is absolutely unacceptable to sell a product on its insulation performance!
If you have any pride in being a mid-to-high-end car or selling its performance,
Rather than deceiving with sales talk that is close to false, they are honest and state their specifications, and are categorized as "mid- to high-end" and "major"
I want them to protect the brand.
