From a flow society to a stock society.
Here's how to increase demand and value for used homes. In order to make Japanese people want used houses, it is necessary to eliminate the desire to build new houses. In order to achieve this, it is necessary not only to make used houses more attractive by renovation, but also to make new houses attractive after they have become used houses.

Japan as a flow society

Japan is a flow society where houses are destroyed in about 30 years.
Houses are made in accordance with it.

We call "stock-type house" houses that have been built for a long time to produce "tastefulness" and "Value" like the modern West.
We have decided to call houses that are optimized to be destroyed quickly, such as those in present-day Japan, "flow type house".

Japanese houses spend a lot of money on structures such as foundations and pillars, and they have a long life.
However, I learned that using inexpensive materials with short lifespan for exterior walls and flooring, which cost a lot of money to replace, is a challenge for becoming a "stock-type house".

For example, in Western new houses, bricks, tiles, and high-quality wood are used to produce "tastefulness" and "Value" over a long period of time, but many Japanese houses are made of materials such as artificial new building materials that are not valuable even when they are old.

One example is siding, which is used on walls.

Siding is clean at the time of new construction and cheaper than other materials, but even if it is maintained regularly, it will deteriorate after 30 to 40 years and it will end its life, and replacement work will be necessary.
And the cost is at least 2 million yen, which is more expensive to maintain than building materials that last longer.

This is because people choose houses that are made of materials that are cheaper and look better when they are newly built than materials that, even if slightly expensive, will have a taste after 10 years.

They are not made with the idea of making the house last longer, so as the age of the house increases, its value decreases and it is rebuilt.

To repair only necessary parts without rebuilding everything and to increase the value.
Because of this economical efficiency, there is an economic margin and it can be inherited as assets at the time of inheritance.

A stock-oriented society not only makes homes attractive, gives them market value, and brings solutions to the problem of vacant houses, but it also gives many people who live in an ecological and social environment more economic leeway.
This is common and feasible in Europe.

So what exactly should we do to make the transition to a stock-type society?

Compared to Europe, the difference between Japan and Europe lies in these two points.
・the preference of people or markets for older houses ・The new house is built with the idea that it will become valuable as an old house after 10 or 100 years.

[The house makers]
・Building housing in a stock-type society where people can create value over time in the future
(If there is no one to buy, you can't make it, but if there is no company to make it, you can't buy it, so it's important to prepare option.)

・To understand the value of an old house by eliminating a desire to build a new house.
・Buying a home that you can value because it's old.

A stock-type society is the same as a flow-type society, It is not a system based on the premise of subsidies, but basically an independent economy.

For example, a house manufacturer that used to earn money by building a lot of new houses will shift to a business model that earns money through after-sales services such as repairs.

Other than that, the initial investment of the loan increases more than before, but if the house is easy to keep the value, it is good as a collateral, so you can get credit easily, and the interest rate will be lower accordingly.

However, to do so, many buyers must be aware of the value of stock-type houses so that they have a high value in the used market.

Until such a market can be realized, I think it would be good to have a special subsidy from the government.

If stock houses can be purchased without increasing the burden, more people will purchase stock houses, accelerating the transition to a stock society.

But,the most important thing is that we Japanese, the buyers, change.
