The U.K. government said Friday it wanted to hear from businesses and members of the public about their priorities for a post-Brexit trade deal with Japan.

Japan is one of the U.K.'s biggest foreign investors, encouraged by successive British governments who have promised a business-friendly base from which to trade across Europe.

The U.K.'s decision to leave the European Union has raised concern that Japanese firms will shift operations elsewhere if tariff-free trade ends with the rest of the European bloc.
