Japan's exports hit a record high in October and the trade surplus jumped by two-thirds from a year earlier, though the increase was slightly less than forecast, raising concerns that a slowing U.S. economy will hurt Japan's export-led growth.

But firm shipments to Europe, China and other parts of Asia offset a decline in exports to the United States, pushing overall exports up by 13.9 percent from a year earlier and underscoring the view that exports remain solid at least for now.
