As Japan's fifth-biggest oil provider, Kuwait supplied 5.4% of the Asian nation's total crude imports, the Japanese Natural Resources and Energy Agency said in a preliminary report. 
Japan's overall imports of crude oil increased 6.7% year-on-year to 3.13 million bpd in June, expanding for the third month in a row, according to Kuwait News Agency (KUNA).
