Japan posted a current account surplus for the 22nd consecutive month in April, the government said Wednesday, as declining crude oil prices reduced imports and rising numbers of foreign tourists pushed up a travel surplus.

The current account surplus expanded 41.7 percent from a year earlier to ¥1.88 trillion, the Finance Ministry said.

Among key components in the current account, one of the widest gauges of a country's international trade, goods trade registered a surplus of ¥697.1 billion, a reversal from a deficit of ¥132.0 billion a year earlier.
