New blood may not necessarily support the LDP

Japan welcomed 1.21 million 20-year-olds into adulthood on Jan 11. But two years before their coming of age, Japan's young people will have the right to vote for the Upper House election in summer. The country's Diet enacted legislation in July 2015 to lower the minimum voting age to 18 from 20-the biggest reform of the nation's electoral laws in 70 years. The change is expected to add 2.4 million voters to Japan's voting pool.

The Japanese government claims that the change is important as the "voices of young people will be more reflected in politics".

The legislative change came as the ruling Liberal Democratic Party headed by Prime Minister Shinzo Abe seeks to revise the country's war-renouncing Constitution for the first time since it took effect in 1947.
