The development of technology and international economic cometition causes drastic changes in the industrial structure as well as the decline of old or comparatively disadvantaged industries in a national economy.
The national government usually adopts industrial adjustment policies, or so-called soft landing policies in order to minimize such social problems as unemployment, bankruptcy and depressed regional economies.
In Japanese postwar history the most representative industry to decline due to such a comparative disadvantage is the coal industry, which had played a central role in Japan's energy supply since the Industrial Revolution. In this paper we describe the Japanese Government's soft landing policies for the coal mining industry and focus on the coal mining area development policy.
The coal mining area development policy has been based on the plan provided by Coal Mining Area Development Act of 1961. The budget for developing coal mining areas has totaled 208 billion yen from 1967 to 1994, or an average of 7.4 billion yen per year. This policy has adopted three main measures.
The first measure was the establishment of the Japan Regional Development Corporation, a government corporation which has since developed industrial parks in coal mining areas. By the end of fiscal 1992, 136 industrial parks covering 4, 114ha had been constructed.
Secondly, the central and local governments have endeavored to induce factories to coal mining areas by financing or providing subsidies to newly located factories in these areas. By the end of fiscal 1992, 5, 406 factories had been built in coal mining areas, of which 3, 618 factories had been located in industrial parks constructed by the Japan Regional Development Corporation. It is clear that the government corporation has played an important role in inducing many factories to these areas.
The number of workers employed by newly located factories in industrial parks has now reached 140, 000. Considering that the number of persons who lost their jobs because of the coal mine closures has been calculated to be 226, 000, without a doubt these newly located factories in industrial parks have also played an important role in employing for unemployed persons as well as their family members.
The shipment of finished goods from manufacturing industries in coal mining areas increased by about 28 fold from 1960 to 1990, while, overall, the Japanese manufacturing industry increased by about 21 fold in the same period.
Thirdly, the Government has given Coal Mining Area Development Grants to local governments in order to solve many of the resultant social problems. Regarding this policy, it remains difficult to conclude whether or not such a policy has succeeded in improving the financial condition of the local governments.
Though the Government has endeavoured to develop coal mining areas, the population of these areas has substantialy decreased. The population of the coal mining areas decreased from 3.0 millon to 2.1 millon, or by 30%, from 1960 to 1975 and has since remained at 2.1 millon from 1975 to 1992.
However, it is noticeable that there are clear differences between coal mining areas in regard to the changes in population.
The first group consists of the Rumoi, Tenhoku and Amakusa coal mining areas, where the population has continued to decrease drastically because of the depressed coal mining, agriculture and forestry industries.
The second group comprises the Ishikari and Takashima coal mining areas where the population has also continued to decrease drastically because of the closure of major coal mines.
The third group includes the Chikuho, Karatsu and Sasebo coal mining areas where the population decreased drastically from 1960 to 1975 because of the collapse of the coal mining industry but thereafter slightly increased from 1975 to 1993 as a result of the coal mining area development policy.
