Japan's exports likely fell at a faster pace in May, down for the sixth straight month, as the U.S.-China trade war takes a toll on the economy, a Reuters poll showed Friday.

The Bank of Japan is expected to keep its targets for short-term interest rates and its long-term government bond yield unchanged next week, according to the poll.

Consumer prices, another key gauge for market watchers on policy, likely edged down in May, putting pressure on the BOJ as it remains far from achieving its elusive 2 percent inflation target.
