The candidates in Japan's elections have made their final appeal to voters before a poll that is expected to bring the opposition into power.

The latest surveys indicate the ruling Liberal Democratic party (LDP) of Taro Aso, the incumbent prime minister, is at risk of losing power on Sunday after leading the country for most of the past 50 years.

But the impetus for Japan's voters appears to be frustration with the LDP, rather than enthusiasm for the opposition.
