Irans crude oil exports to Japan surged 61% in May from a year earlier, the Iranian news agency Shana reported on Saturday, citing data from Japanese Ministry of Economy, Trade and Industry.
Japan took in 308,000 barrels per day (bpd) of Iranian crude in the period, 117,000 bpd more than what it imported a year earlier, the report said.
That put Iran on the fourth place behindSaudi Arabia, UAE and Qatar as the biggest exporters of crude to Japan which brought in 3.32 million bpd in May.
Saudi oil exports fell three percent in the period from a year earlier to 1.2 million barrels per day, according to the Japanese ministry data.
The report said Iran is seeking to raise its crude shipments and establish itself as the third exporter to Japan.
Japan was one of the key clients of Iranian oil with 338,000 bpd of imports before Western sanctions on the Islamic Republicin 2012. During years of the sanctions, the Asian country continued to import crude from Iran, though at limited volumes, under a preliminary nuclear agreement.
Iran hosted several leading Japanese companies in its oil and gas projects before the sanctions were imposed.
After the removal of sanctions, Asian imports of Iranian oil have risen sharply. Iran's oil flows to Europe have also begun to pick up after a slow start.
Imports by Iran's top four buyers - China, India, Japan and South Korea - roseto 1.56 million bpd in March, up 49.9 percent from a year ago. Before 2012, Iran exported around 2.3 million bpd, with more than half going to Asia, mainly China, South Korea, India and Japan.
The surge inexports points to Iran's success in regaining market share after the sanctions were eased in January.
Irans oil production has already hit the highest level in the past five years. Since December, Irans oil production has climbed by 740,000 barrels a day to 3.63 million in June.
On Monday, Mohsen Qamsari of the National Iranian Oil Company (NIOC) said the country has regained about 80% of the market share it held before 2012.
