Until the 1990s, economic ties between the European Union and Japan were marked largely by an atmosphere of trade tension. The main reason was the persistent trade surplus that Japan maintained. Over time, however, the improvement of the bilateral trade balance and the massive direct investment of Japan in the EU have alleviated these tensions.

Japanese firms are increasingly involved in various global business operations - not only in traditional international trade in goods, but also in offshore production and the new mode of globalization: offshore outsourcing.

Nuclear fission was discovered in the late 1930s. The first application went towards military use, and gradually expanded to civil use such as power generation. Power generation gained importance in two stages: firstly, to shift away from oil in power generation after the oil shocks in the 1970s, and second, to arrest climate change due to CO2-free nature of nuclear power more recently. This typically applies to Japan, which has become the world third largest in nuclear power generation. However, nuclear power is violent by nature, and major accidents of nuclear power plants shook the public confidence in nuclear safety. Japan has been put into such situation in a most radical way due to the Fukushima nuclear disaster of March 2011.

Productivity is increasingly important in the Japanese economy as an aging and shrinking population is expected to constrain labor input. Thus, the creation of innovation is critical for realizing economic growth and maintaining Japan's international competitiveness. Specifically, emerging countries such as China and South Korea are quickly catching up on Japan's level of technological prowess in electronics and other high-tech industries. For that reason, continual investment in R&D and provision of products and services that are competitive in the global market are crucial for Japan's international competitiveness.
