源自美国的页岩油气革命，促使世界能源供给结构正在发生巨大变化。另外，受东日本大地震的灾害影响，日本国内全部核电站至今依然处于停机状态。天然气火力发电及石油火力发电随即增多，而进口燃料的增加导致贸易收支情况恶化，其对日本的负面影响开始显现。鉴于此前主要依赖核电的能源政策难以为继，为确保天然气供给渠道的多元化，日本强烈期待能从美国进口LNG。本文将综观世界及日本的能源形势，并据此就日本的一次能源（石油、天然气、煤炭）供给现状和今后的发展趋势做简要介绍，此外，还将对世界，特别是今后能源需求旺盛的亚洲的能源状况及趋势进行讨论。
Shale oil and gas revolution，originated from the United States，has made the world energy supply structure significantly changed. On the other hand，Japan’s nuclear plants are still in suspension because of East Japan earthquake. Natural gas and oil powered energy has increased，trade balance has deteriorated because of increasing fuel import，and negative effects emerged. Providing the unsustainable dependence on nuclear power，Japan has a strong motive to import LNG from USA to diversify natural gas supply channel. Based on energy situations in Japan and the world，this paper briefly introduces Japan’s current and future primary energy supply（oil，natural gas，coal），and discusses future energy situation and trend in the world and Asia in addition.
