The deal signed in Tokyo by the EU's top officials and Japan's Prime Minister Shinzo Abe creates a free trade zone covering almost a third of the world's GDP. According the European Commission, the deal is projected to eliminate just under $1.2 billion worth of tariffs for EU exporters and double the amount for Japanese firms.
"It is expected that this agreement will promote the liberalization and facilitation of trade and investment between Japan and the European Union and will further vitalize both economies by strengthening reciprocal economic ties", the Ministry of Foreign Affairs of Japan said in a statement said.

"We are showing that we are stronger and better off when we work together".
That follows an earlier move by Washington to impose 25% tariffs on 34 billion dollars (£25 billion) of Chinese goods.
Mr Trump pulled the United States out of the Trans-Pacific Partnership with Japan and 10 other states on his first day in office in January 2017 and has pushed to renegotiate a free trade pact with Canada and Mexico.
