The leaders of Japan's six major political parties traveled a distance of 10,500 km on average during the 12-day campaign for Sunday's House of Representatives election.

The average distance that the party leaders covered traveling from one city to another over the period through Saturday, stumping for candidates backed by their respective parties, is further than the distance between Tokyo and London.

Prime Minister Junichiro Koizumi, also president of the ruling Liberal Democratic Party, covered a distance of 8,900 km in total -- well below the average of the six leaders because he had to spend more time in Tokyo carrying out his public duties.
