Introduction Japan, both as a resource-poor country and as the world's third biggest oil consumer (British Petroleum, 2007), has depended on imported oil for almost 100% of its domestic demand (99.6% in 2006). In its modern history the Japanese economy and foreign policy have always been constrained by the security issues posed by oil supply. The outbreak of the Pacific War (1941–1945) and the subsequent defeat, and the first negative growth since the end of the War after high-flying growth (1974) were caused by a disruption of oil supply either directly or indirectly. These bitter episodes are firmly established in the mind of the Japanese nation. As an alternative to colonizing oil producing countries to reduce its vulnerability of high dependence on foreign producers, Japan has long made efforts after the War to increase its self-developed oil production in overseas oil fields. Self-developed oil production means that Japan is directly involved in production and operation projects and takes risks on it. As a result, it is expected to contribute toward the long-term supply stability, timely prediction of changes in the market, understanding of global trends of exploration and development, and a wide-ranging and interdependent relationship with oil-producing countries. Also recently, reflecting a major structural change in the international energy market, the Japanese government announced the New National Energy Strategy of 2006 with a new numerical target of 40% of total oil import secured by the self-development. This paper tries to indentify how Japan has struggled to achieve its national targets in securing overseas oil reserves and to what extent the development of technology meets the policy planners' expectations. It is widely understood that the expansion of financial support by the government is limited in Japan and cannot be a panacea in the current
