Your Party, an opposition group once seen as a possible third force in Japanese politics, decided Wednesday to disband, amid dismal public support and a desperate split between members over whether or not to cooperate with the ruling camp in trying to survive the Dec. 14 Lower House election.

At a general meeting, the 20-member party voted to disband, with 13 voting for the measure and six opposed. The latter group included party founder and Lower House member Yoshimi Watanabe.

Watanabe has argued that Your Party should cooperate with the ruling camp to realize the party's key policy proposals, most notably cutting the size of government to save taxpayers' money.
