The Democratic Party of Japan, the largest opposition party, has established a task force charged with bolstering the party's support among women voters in the House of Councilors election slated for July.

"Women comprise half the population, and the DPJ must attract their interest and have them participate," Wakako Hironaka, a female DPJ member of the House of Representatives who heads the task force, told reporters Tuesday.

The DPJ also placed under the task force an action group called Let's Change Japan with Women's Dynamism.
