With Japan’s opposition wracked by infighting, any challenge to Prime Minister Shinzo Abe’s grip on power -- as his popularity slides after a series of scandals and missteps -- is likely to come from his own party.

Most lawmakers from the ruling Liberal Democratic Party are members of factions, in a system that dates back to the party’s founding in 1955, when two conservative groups merged. The combined entity has gone on to dominate Japanese politics, in power for all but a handful of years over the past seven decades.
