In Sunday's Nagoya city assembly election, a local party led by Nagoya Mayor Takashi Kawamura became the No. 1 party. Although his Genzei Nippon (Tax Reduction Japan) failed to gain a majority in the 75-seat assembly, each of the traditional parties lost assembly seats.

Genzei Nippon's strength increased from one seat to 28. The Democratic Party of Japan, which used to be the No. 1 party with 27 seats, garnered only 11 seats and became the No. 4 party. The strength of the Liberal Democratic Party fell from 23 seats to 19 seats; Komeito, from 14 seats to 12 seats; and the Japan Communist Party, from eight to five. The Social Democratic Party lost its only seat.

The election was held after the assembly was recalled in a Feb. 26 referendum. In late August 2010, Mr. Kawamura had started a signature collection movement to hold the referendum. He aimed to change the composition of the assembly so that it would approve his call for making permanent a 10 percent residential tax cut and for halving the number of assembly seats and the amount of assembly-member salaries. In one month, he collected 369,008 signatures from voters, enough to hold the referendum.
