It emerged as a major economic player in the decades following the second world war. Only the US and China now have larger economies. Japan is a parliamentary democracy, but the conservative Liberal Democratic Party (LDP) has governed almost continuously since it was formed in 1955. Its current leader, Shinzō Abe, has been prime minister since 2012 and in 2016 wona snap general election. The next general election is set to take place by October 2021. In 1997, Japan hosted the third formal meeting of the UNFCCC (United Nations Framework Convention on Climate Change) in Kyoto, its former capital.
