Shunya Saito, 17, doesn't think about the Constitution or politics.

In fact, none of his classmates at Funabashi Kita High School in Chiba Prefecture picked constitutional revision from the 50 topics provided for a recent debate class.

Although the new voting age of 18 will allow him to vote in what is shaping up to be one of Japan's most pivotal elections ever, Saito and his peers say the most pressing issue now is motorcycles, and why they are banned from using them to go to school if they can get a driver's license at age 16.
