It was a nationwide network of prefectural assembly members, usually running on local platforms variously named as "living citizen network", "living club", "living cooperative" or the Rainbow and Greens 500-Member List Movement .
The national spokespersons for the party were Kiyoshi Matsuya [1], former Shizuoka Prefecture assembly member and the city councillor Mutsuko Katsura [2] in Ibaraki, Osaka.
The symbol of the "rainbow" represents diversity, solidarity and the cooperation which respect personal differences; the colour "green" signifies conversion to an economy which coexists with natural environment.
In the 2004 parliamentary election, this network of local groups supported the Democratic Party of Japan and the conservative-leaning national Green party Environmental Green Political Assembly (Midori no Kaigi).
Kawada announced that he will organize a Green party group in the House, helping the Rainbow and Greens to become a national political party.
