TOKYO: Japan holds an election Sunday for the upper house of parliament that could affect the country’s direction. While Prime Minister Shinzo Abe’s ruling party is seeking a mandate for his leadership by emphasizing his economic revitalization policies, several opposition parties are coordinating a negative campaign, cautioning voters that a landslide for Abe would give him an upper hand to revise the pacifist post-World War II constitution.

Here are five main points about the election:

1-A TWO-THIRDS MAJORITY

2- ABENOMICS VS. CONSTITUTION

3- ABE’S AMBITIONS

4- OPPOSITION ALLIANCE

5- TEENAGE VOTERS
