by Editor’s note: Daiwa House is the largest residential builder in Japan.
Founded in 1955 and headquartered in Osaka, Daiwa House is one of the world’s top 500 group enterprises focusing on the residential industry, ranking first in the industrial residential construction industry in Japan.
Prefabricated construction website (www.precast.
com.
cn) launched an exclusive interview with Mr.
Liu Kang, Executive Director of Dahe Housing (China) Investment Co., Ltd.
I hope that through this article, you can deeply understand the differences in the development of prefabricated buildings between China and Japan, learn the advanced concepts of Japan, and increase the development of prefabricated buildings in China.
Introduction: Liu Kang, after graduating from Tongji University in 1999, studied at Osaka University in Japan as a Sino-Japanese exchange student, studying for a postgraduate degree.
After graduation in 2002, he entered Dahe House, where he worked as a project manager and technical research.
At the beginning of the Baoye and Dahe Joint Venture Industrial Housing Project, he officially returned to China to engage in industrial research.
Now he is the executive director of Dahe House (China) Investment Co., Ltd.
Daiwa Housing Industry Co., Ltd.
is the inventor and creator of prefabricated housing in Japan, and is also the leading enterprise in the construction industry in Japan.
The company has 42460 formal employees, 317 subsidiaries of the group, and the operating revenue in 2017 was 34.3 billion US dollars.
Its overseas business covers more than 30 countries, including the United States, Australia, China, and Southeast Asia.
It ranks 342 in the World 500 in 2018.
The opportunity for Daiwa House to enter China begins with the resumption of diplomatic relations between China and Japan.
In 1972, China and Japan resumed diplomatic relations, and the founder of Daiwa House, Mr.
Nobuo Ishihashi, led the Japanese construction industry delegation to visit China as the head of the delegation.
In Beijing, the visiting delegation was cordially received by the then Vice Premier of the State Council, Wang Zhen (also honorary president of the China-Japan Friendship Association and honorary president of the China International Friendship Liaison Association).
At that time, while Shanghai was preparing for the National Games, it was faced with the problem of housing shortage.
As China’s housing construction was relatively slow, the government proposed to Dahe Housing whether there could be a solution to the housing problem of athletes.
Finally, in just three months, Dahe House successfully completed the construction of five dormitory buildings for athletes in Shanghai, with a total area of about 10000 square meters.
And all materials were transported to Shanghai from overseas, laying a good foundation for the success of the National Games.
Through this project, the speed and quality of building houses in Dahe broke the Chinese people’s outdated understanding of integrated houses at that time, and became famous for a time.
In the 1980s, Dahe House officially entered the Chinese market and built five residential community projects in Beijing, Shanghai, Tianjin, Dalian and other places in an all-import way.
After 2000, Dahe House focused on the Jiangsu market.
It has successively developed fully hardbound residential quarters in Suzhou, Wuxi, Changzhou, Nantong and other places.
For this purpose, it has set up supporting property companies, which are operated and maintained by Dahe independently.
Through this action, it not only improves the customer’s evaluation of the house, but also promotes the improvement of the price of second-hand houses.
In 2006, Dahe House, together with Tongji University, the Chinese Academy of Building Sciences and other scientific research institutions, jointly developed and launched prefabricated buildings suitable for the living habits of the Chinese people, and obtained the national demonstration.
In 2013, Dahe Housing Industry Co., Ltd.
and Zhejiang Baoye Real Estate Group Co., Ltd.
jointly established an industrial building manufacturing factory in Shaoxing, Zhejiang.
At present, the annual production capacity of the factory reaches 100000 square meters.
According to Mr.
Liu Kang, the executive director of Dahe Housing (China) Investment Co., Ltd., although Dahe Housing has promoted some products in the United States, Australia and Malaysia, they are all exported from Japan to the local market.
In addition to Japan, Daiwa is really responsible for the technical management of the factory, and the only one that uses Daiwa LOGO is Baoye Daiwa, which shows that Daiwa House attaches great importance to the Chinese market.
Mr.
Liu Kang told the editor that the concept of industrialized housing in Japan began around 1955.
They collectively referred to low-rise prefabricated housing, temporary school buildings, offices, and PC-style multi-storey collective housing as “prefabricated buildings”, that is, buildings that were produced in the factory in advance and then assembled on the site.
In 1973, the Ministry of Construction of Japan issued and implemented the prefabricated housing performance certification system, which officially used the name “industrial housing performance certification system” for the first time.
Industrialized residential buildings not only have the characteristics of simple factory production, but also emphasize the characteristics of highly industrialized technology integration including residential comfort and other performance.
The earliest prefabricated construction company, Daiwa Housing Industry Co., Ltd., took the lead in developing steel tube houses in 1955, which is also the prototype of industrial housing.
The period from 1965 to 1980 was the growth period of Japanese industrial housing.
In 1966, the Japanese government announced the “five-year plan for the first phase of housing”, which aims to build 6.7 million homes within five years and achieve the goal of one family and one home.
The Japanese government has focused on realizing the mass supply of housing through industrialization and formulated many promotion policies.
It is also during this period that the government began to put forward the concept of “housing industry”.
The period from 1981 to 1999 was the groping period of Japanese industrial housing.
After 1986, following the trend of the foam economy, Japan’s residential commodities also became more luxurious, and the equipment used in the housing also stepped into the advanced route.
After 2000, Japan’s industrial housing entered a period of innovation.
After decades of experience accumulation, Japanese companies have been on a par in terms of technology such as the quality of industrial residential production.
Under the fierce market competition, with the global energy conservation, environmental protection, and sustainable development concept, the major residential companies in Japan have put more emphasis on innovation beyond the housing itself.
