Tokyo Governor Yuriko Koike threw her hat into the ring of national politics Sept. 25 by announcing she is forming a new party.

Koike told a news conference in which she also announced the name of the giant panda cub born at Tokyo's Ueno Zoo on June 12 that the party is to be called Kibo no To (Party of hope).

Masaru Wakasa, a Lower House member with close ties to Koike, has been working to gather members for the new party.

They include Goshi Hosono, a former environment minister who recently bolted from the main opposition Democratic Party, as well as other lawmakers who have quit other parties.

Koike said the new group was being formed because there was a need for authentic reform and that she wanted to recruit individuals who harbor similar ambitions.

Among the planks Koike said would be used to build a platform for the new party were administrative reform, the comprehensive release into the public domain of government information, a new economic growth strategy to replace the "Abenomics" package of measures and also constitutional reform.
