Former Tokyo Gov. Shintaro Ishihara and his breakaway group of lawmakers have decided to call their new party Jisedai no To, which roughly means "party for new generations," they announced Thursday.

The name was chosen from about 600 suggestions sent in from the public.

The group of 22 have all but broken from Nippon Ishin no Kai (Japan Restoration Party) and plan to launch the new party in August.

Ishihara said one of their priority concerns is to help younger generations solve the serious problems they face, such as the widening disparity between rich and poor and difficulties getting married and finding financial security.

"We all share the same sense of crisis . . . It's our responsibility to fix those problems so that younger generations can have hope for the future," he said.

But at a news conference Thursday, party members did not unveil specific policies for younger generations, such as those concerning the sustainability of social security.

Hiroshi Yamada, a senior group executive, said the party will try to hammer out a basic platform by the end of July. The group is apparently trying to build a fresh, youthful image because the 81-year-old Ishihara is known for his nationalistic views, and his group includes many elderly, conservative lawmakers.

During the news conference, younger lawmakers took the front-row seats while Ishihara and the other senior members sat in back.

Ishihara, who is rumored to be close to sitting out the next Lower House election, did not take the post of interim president, which will remain in place until the party's formal launch in August.

The 19 Lower House members and three Upper House members broke away from Nippon Ishin to support Ishihara's call for the creation of a new constitution that does not renounce war.
