Coalition, allies of prime minister win majority of the seats in the upper house of parliament

Japanese Prime Minister Shinzo Abe, seeking to allay concerns he would divert energy from fixing a fragile economy to revising Japan's pacifist constitution after a big election win, said on Monday changing the charter would not be easy.

Abe's coalition and allies won two-thirds of the seats in parliament's upper house in Sunday's election. That victory, with the ruling bloc's super majority in the lower house, opens the door to revising the constitution for the first time since its adoption after Japan's defeat in World War II.
