Hundreds of Japanese, young and old, gathered in downtown Tokyo in a peaceful protest Friday against calls by Prime Minister Shinzo Abe to amend the country’s pacifist constitution and give the government more power to abridge civil liberties.

Opposition parties, labor groups, religious organizations and individuals turned out to march from a park near the Imperial Palace through the Ginza shopping district, beating drums and chanting their opposition to such moves by Abe and the ruling Liberal Democratic Party.
