Japan's Nikkei share average ended lower on Wednesday, with automakers leading the losses, amid concerns about the impact of U.S. President-elect Donald Trump's tariff pledges and a stronger yen. The Nikkei fell 0.8% to close at 38,134.97 and the broader Topix lost 0.9% to 2,665.34. On Monday, Trump pledged to impose new tariffs on imports from Canada, Mexico and China.
