Although the right to vote was something few 18- and 19-year-olds in Japan were pushing for or even interested in, the change is good news for the country, one educator says.

Daisuke Hayashi, 39, an assistant professor at Toyo University, who has been an advocate of lowering the voting age for nearly two decades, believes this could be an important exercise in democracy for Japan.

"It is the first time that there was this much attention" on granting younger people voting rights, Hayashi said.
