Japanese high school students preparing to attend this year's Nobel award ceremony as peace ambassadors have pledged to keep up their efforts to abolish nuclear weapons.

The students held a news conference in the city of Hiroshima on Monday, ahead of their trip to the Norwegian capital Oslo.

They are scheduled to attend the December 10 ceremony together with members of Nihon Hidankyo -- a group representing survivors of the atomic bombings of World War Two that won this year's Nobel Peace Prize. The students also plan to visit a local high school with survivors for a discussion.

Kai Natsuki, one of the students whose great-grandfathers were survivors, was with a Nihon Hidankyo member when the group was announced as the winner of this year's peace prize. Kai said she is excited to share the joyful moment again in Oslo. Kai pledged to continue her activities bearing in mind an anti-nuclear message bestowed on young people.

Another student, Ohara Yuka, said 79 years have passed since the atomic bombs were dropped on Japan. Ohara, whose grandmother experienced the effects of an atomic bomb firsthand, said there are still lingering issues and that she will highlight this fact during the school event in Norway.
