According to NHK, Iran accounted for 5.5 percent of Japan's crude oil imports in 2017 and the government attaches importance to imports of energy resources from various countries. Thus, Tokyo plans to seek to be exempt from this embargo.
Earlier in the day, the second package of US sanctions, re-introduced after Washington's withdrawal from the Iran nuclear deal and targeting, in particular, Iran's oil sector, took effect. Washington granted Japan, among other countries, a temporary exemption from the sanctions, however, Tokyo asked to prolong the period.
In May, US President Donald Trump announced that the United States would withdraw from the Iranian nuclear deal, and reimpose its sanctions against Iran that had been previously lifted under the agreement. The first round of the US restrictions came into force in August.
