Stockpiling of petroleum in japan is performed in three programs. First, there is national stockpiling, which is run directly by Japanese government. Second, there is private stockpiling, which by law must be performed by private oil companies. Third, there are stockpiles held jointly in collaboration with oil-producing nations. The three programs have a combined stockpile of approximately 80 million kiloliters of petroleum (equivalent to approximately 208 days of domestic consumption, as of the end of Match 2017).
Stockpiling of petroleum gas (LP gas) in japan is being promoted through two programs: the national stockpiling program which is directly controlled by the government, and the private-sector stockpiling program which is implemented by private companies under obligation by law. Two programs have a combined stockpile of approximately 2.8 million tons of LP gas (equivalent to approximately 104 days of import volume, as of the end of March 2017).
