The Environmental Green Political Assembly (みどりの会議 Midori no Kaigi ) was a right-wing political party in Japan which had a mix of platforms. It advocated Green conservatism but was also reformist. On June 22, 2004, because of the poor performance the party showed in the 2004 Upper House elections (the party won no seats), it dissolved itself, not merging into any other party, spelling an end to the Sakigake movement in Japanese politics.
The party grew out of the Sakigake Party, which renamed itself to Midori no Kaigi after it adopted a policy of ecologism. Sakigake itself grew out of the New Party Sakigake movements of the 1990s.
Midori no kaigi had most of its support from the ecologists of Japan, as well as some people who left the ruling Liberal Democrats.
On domestic policy the party was ecologist, conservative, and right-wing reformist. It tended to support, like the Liberal League, the ruling Conservative bloc, made up of the Liberal Democratic Party and the New Clean Government Party.
The party, however, had no seats in the Diet, even though it made a goal of one seat in the House of Councillors election in July 2004, which it did not gain. On July 22, 2004, Midori no kaigi dissolved itself, not grouping itself into a new party, but just dissolved - spelling an end to the Sakigake movement of Japanese politics. The dissolution was registered with Ministry of Internal Affairs and Communications on October 31, 2004.
