Three 18-year-old high school students at Shinagawa Joshi Gakuin in Tokyo said they were excited to cast their ballots in Sunday's Upper House election, being among the nation's first teenagers to join the electorate.

"Just the thought of having a chance to possibly change the future (of this country), and the prospects of seeing more policies addressed to younger generations makes me excited," said Rena Yamaguchi, a third-year student at the school, while her two fellow students nodded.

"It's a historic event, and I'm proud to be among the first 18-year-olds to vote," agreed Mizuki Inoue.
