Japan–United Kingdom relations

Foreign relations between Japan and the United Kingdom (日英関係, Nichieikankei) were established on 26 August 1858 and involve diplomatic, economic, and historical ties between the two countries.

Both countries are members of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, G7, G20, International Criminal Court, OECD, United Nations, and World Trade Organization. They also share a free trade agreement called the Japan–United Kingdom Comprehensive Economic Partnership Agreement, a tax treaty, and a reciprocal access agreement; the United Kingdom is one of only three countries to share the latter with Japan, and is the only European country to do so.
