Finance Ministry officials say Japan posted its 4th straight monthly current account surplus in May.
The current account is the broadest measure of international trade of goods and services.
The officials said on Tuesday that the surplus was worth 5.1 billion dollars in May. That's down 7.7 percent from the same month last year.
The trade deficit for May was about 6.6 billion dollars.
But the primary income account, which measures how much the country earns from overseas investments, had a surplus of about 14.5 billion dollars.
