The United States took into account stable energy supply and the impact on Japan firms in granting a waiver, Seko told reporters, adding that Japan will continue to exchange views closely with the United States, Reuters news agency reported.
"It would be up to the judgment of private firms, but based on this decision, the (Japanese) companies would likely prepare for resuming Iran crude imports," he said.
Asked whether any cuts in imports would become necessary, he said "I cannot comment on import volumes."
Seko also declined to comment on whether Japanese imports would fall to zero after the 180-day exception period expires, saying that would depend on future negotiations between the two nations.
