Japanese companies overwhelmingly want Prime Minister Shinzo Abe's ruling coalition to stay in power in this Sunday's national election but about two-thirds want it to lose seats, a Reuters poll found.

The survey suggests corporations want political stability but don't want to hand Abe a landslide victory for fear he might become complacent about reviving the economy.

Many companies in the survey expressed concern that a big election win would encourage Abe to invest his energy in his long-held ambition to revise the pacifist Constitution, at the expense of economic policy.
