The two countries share a close alliance since the 1951 Treaty of San Francisco and 1960 Treaty of Mutual Cooperation and Security. The U.S. maintains military bases in Japan; Japan is a major non-NATO ally. They are each other's significant trading partners and cultural influencers—but remain distinctly independent nations with separate governments, laws, currencies, and international representation.
