Japan has many current allies, the largest of which is the United States. Because Japan is a member of the United Nations and participates in the G-8 and G-20 summits, many of the countries also participating in those groups are considered allies of Japan.
The United States and Japan have an alliance that is key to the safety, economic stability and political freedom of the Asia-Pacific region. The two countries work together to establish security measures, financial growth and global development.
Another of Japan's allies is Australia, a member of both the United Nations and G-20. Both countries work with the United States to develop strategy and diplomatic relations in that part of the world. Japan also has an ally in the Republic of Korea, commonly known as South Korea. These countries develop policy regarding North Korea, with help from their other allies, including the United States.
Other members of the G-8 that Japan considers allies include the United Kingdom, France, Germany, Italy, Russia and Canada. These countries, along with the United States, work together to develop economic policies, handle any global crises and discuss energy use, terrorism and global security. Japan is part of the G-20, which includes the G-8 nations and other allies, such as South Africa, Turkey, Saudi Arabia, Brazil, India and Indonesia.
