Imports fell by 234,000 b/d from April to 2.42 million b/d in May, according to data from the Ministry of Economy, Trade and Industry (Meti) (IOD Jun.1'21). However, May imports rose by 134,000 b/d from the same month of last year. One of the world's biggest crude importers, Japan kicked off major refinery maintenance turnarounds in late April. At least 190,000 b/d of Japanese refining capacity began planned maintenance in late April followed by another 575,000 b/d or more in May. Refineries' crude runs had already declined before the maintenance work started because of weak domestic demand caused in part by the coronavirus pandemic. Refineries' capacity utilization sank from 70.7% in the week ending Apr. 10 to just 58.1% in the week ending May 22, according to the Petroleum Association of Japan (PAJ). It recovered slightly to 62.9% in the week ending May 29. Japan's Top Crude Suppliers ('000 b/d) May'21 Apr'21 Chg. May'20 Chg.
