Exports
Japanese exports grew rapidly in the 1960s and 1970s, but growth slowed considerably during the 1980s. Over these decades, both the composition and the reputation of products from Japan changed profoundly.
Because of the success of certain exports, Japan is often viewed as a heavily export-dependent nation. As an example, just under half of all automobiles produced in Japan were exported.
The growth of Japanese exports during the 1960s and 1970s was truly phenomenal. Beginning in 1960 at US$4.1 billion, merchandise exports grew at an average annual rate of 16.9% in the 1960s and at an average annual rate of 21% in the 1970s. From 1981 to 1988, however, export growth averaged 11.3% per year, about one-half the level of the 1970s. By 1990 merchandise exports reached US$286.9 billion.
The growth in exports can be viewed in terms of both pull and push factors. The pull came from increasing demand for Japanese products as the United States and other foreign markets grew and as trade barriers in major market countries were reduced. Another pull factor was the price competitiveness of Japanese products. From 1960 to 1970, Japan's export price index increased by only 4%, reflecting the high rate of productivity growth in the manufacturing industries producing export products. Inflation was higher in the 1970s, but export prices were still only 45% higher in 1980 than in 1970 (growing at an average annual rate of less than 4%), considerably lower than world inflation. The 1980s began with another short burst of inflation because of oil price increases in 1979, but by 1988 Japanese export prices were actually 23% lower than in 1980, offsetting much of the price increase of the 1980s. This record enhanced the international price competitiveness of Japanese products.
During the 1950s, Japanese export products had a reputation for poor quality. However, this image changed dramatically during the 1970s. Japanese steel, ships, watches, television receivers, automobiles, semiconductors, and many other goods developed a reputation for being manufactured to high standards and under strict quality control. The Japanese were the acknowledged world leaders for quality and design in the 1980s for some of these products. This rise in product quality also increased demand for Japanese exports.
The push behind Japan's exports came from manufacturers. Many recognized that to reach efficient levels of production they needed to adopt a global approach. Manufacturers concentrated on the domestic market (often protected from foreign products) until they reached internationally competitive levels and domestic markets were saturated. Often helped by the large general trading companies, manufacturers aggressively attacked foreign markets when they felt able to compete globally. This push factor partially accounted for the extraordinarily high level of export growth in the 1970s, when the domestic economy slowed; increasing exports was a way for manufacturers to continue expanding despite the more sluggish domestic market. Japanese manufacturers were part of larger conglomerates, the zaibatsu, which provided financing of activities. Thus, they could concentrate on gaining high market shares, without the need to achieve high profits in the process.
Exports included a wide variety of products, virtually all of which were processed to some degree. After the war, the composition of exports shifted through technological progression. Primary products, light manufactures, and crude items, which predominated during the 1950s, were gradually eclipsed by heavy industrial goods, complex machinery and equipment, and consumer durables, which required large capital investments and advanced technology to produce. This process was illustrated vividly in the case of textiles, which composed more than 30% of Japanese exports in 1960, but less than 3% by 1988. Iron and steel products, which had grown rapidly in the 1960s to become nearly 15% of exports by 1970, declined to less than 6% of exports by 1988. Over the same period, however, exports of motor vehicles rose from under 2% to over 18% of the total. In 1991 Japan's major exports were motor vehicles, office machinery, scientific and optical equipment, and semiconductors and other electronic components.
Imports
During the 1960s and 1970s, imports grew in tandem with exports, at an average annual rate of 15.4% during the 1960s and 22.2% during the 1970s. In a sense, import growth over much of this period was constrained by exports, because exports generated the foreign exchange to purchase the imports. During the 1980s, however, import growth lagged far behind exports, at an average annual rate of only 2.9% from 1981 to 1988. This low level of import growth led to the large trade surpluses that emerged in the 1980s.
In general, Japan has not imported an unusually large amount as a share of its GNP, but it has been highly dependent on imports for a variety of critical raw materials. Japan has by no means been the only industrialized nation dependent on imported raw materials, but it has depended on imports for a wider variety of materials, and often for a higher share of its needs for these materials. The country imported, for example, 50% of its caloric intake of food and about 30% of the total value of food consumed in the late 1980s. It also depended on imports for about 85% of its total energy needs (including all of its petroleum and 89% of its coal) and nearly all of its iron, copper, lead, and nickel.
The long-term growth in imports was facilitated by several major factors. The most important was general growth in the Japanese economy and income levels. Rising real incomes increased demand for imports, both those consumed directly and those entering into production. Another factor was the shift in the economy toward greater reliance on imported raw materials. Primary energy sources in the late 1940s, for example, were domestic coal and charcoal. The shift to imported oil and coal as major energy sources did not come until the late 1950s and 1960s. The small size and poor quality of many of the mineral deposits in Japan, combined with innovations in ocean transportation, such as bulk ore carriers, meant that as the economy grew, demand outstripped domestic supply and cheaper imports were utilized.
The price of imports was also a factor in their growth. In 1973 Japan's import price index was at essentially the same level as in 1955, partly because of the appreciation of the yen after 1971, which reduced the yen price of imports, but also because of the reduced costs of ocean shipping and stable prices for food and raw materials. For the rest of the 1970s, however, import prices skyrocketed, climbing 219% from 1973 to 1980. This dramatic price rise, especially for petroleum but by no means confined to it, was responsible for the rapid growth of the dollar value of imports during the 1970s, despite the slower growth of the economy. During the 1980s, import prices fell again, especially for petroleum, dropping by 44% from 1980 to 1988. Reflecting these price movements, the dollar value of petroleum imports rose from about US$2.8 billion in 1970 to nearly US$58 billion in 1980, and then fell a low of US$26 billion in 1988 before making a slight recovery to US$41 billion in 1990.
A third factor affecting imports was trade liberalization. Reduced tariff rates and a weakening of other overt trade barriers meant that imports should have been able to compete more fully in Japan's markets. The extent to which this was true, however, was subject to much debate among analysts. The share of manufactured imports in GNP changed very little from 1970 to 1985, suggesting that falling import barriers had little impact on the propensity to purchase foreign products. Falling trade barriers might become more significant in the 1990s as liberalization continues.
Yet another factor determining import levels was the exchange rate. After the ending of the Bretton Woods System in 1971, the yen appreciated against the United States dollar and other currencies. The appreciation of the yen made imports less expensive to Japan, but it had a complex effect on total imports. Demand for raw material imports was not affected much by price changes (at least in the short run). Demand for manufactured goods, however, was more responsive to price changes. Much of the rapid increase in imports of manufactures after 1985, when the yen began to appreciate rapidly, can be attributed to this exchange-rate effect.
All factors combined led to the rapid growth of imports in the 1960s and 1970s and their very slow growth in the 1980s. Rapid economic growth combined with stable import prices and the shift toward imported raw materials brought high import growth in the 1960s. The big jump in raw material prices in the 1970s kept import growth high despite lower economic growth. In the 1980s, falling raw material prices, a relatively weak yen, and continued modest economic growth kept import growth low in the first half of the decade. Import growth finally accelerated in the second half of the 1980s, when raw material prices stopped falling and as the rise in the value of the yen encouraged manufactured imports.
Japan imported a wide range of products, although energy sources, raw materials, and food were the major items. Mineral fuels, for example, rose from under 17% of all imports in 1960 to a high of nearly 50% in 1980. They had declined to under 21% by 1988. A small increase was experienced by 1991 when mineral fuel imports increased to 23%. These shifts show the enormous impact of price changes on imports. Swings in imports of other raw materials were far less dramatic, and many declined over time as a share of total imports. Metal ores and scrap, for example, declined steadily from 15% in 1960 to less than 5% in 1988 and less than 4% in 1991, reflecting the changing structure of the economy, which moved away from basic metal manufactures to higher value-added industries. Textile materials also dropped from 17% of total imports in 1960 to just under 2% in 1988 and just over 1% in 1991, as the textile industry became less important and imports of finished textiles increased. Foodstuffs, however, were relatively steady as a share of imports, rising from just over 12% in 1960 to 15.5% in 1988. By 1991 a slight decline, 14.5%, was experienced.
Manufactured goods—chemicals, machinery and equipment, and miscellaneous commodities—gained as a share of imports, but the variation among them was considerable. Manufactures were about 22% of total imports in 1960, remained at just under 23% in 1980, and then expanded to 49% by 1988. By 1991 they were just over 45%. Imports of textiles, nonferrous metals, and iron and steel products all showed significant gains, for the same reasons that the raw material imports to produce them had declined. However, chemical and machinery and equipment imports showed little increase in share until after 1985.
The heavy dependency on raw materials that characterized Japan until the mid-1980s reflected both their absence in Japan and the process of import-substitution industrialization, in which Japan favored domestic industries over imports. The desire to restrict manufactured imports was intensified by the knowledge that the nation needed strong manufacturing industries to generate exports to pay for needed raw material imports. Only with the appreciation of the yen after 1985, and the drop in petroleum and other raw material prices, did this sense of vulnerability ease. These trends were reflected in the rising share of manufactures in imports in the late 1980s.
