Tokyo election committees rushed by overlapping polls

Election committees in Tokyo are rushing to prepare as polls for the House of Representatives and Tokyo governorship are set to overlap.

Tokyo is home to around 10.75 million eligible voters. In the last lower house elections in 2009, there were 110 candidates in 25 constituencies and dozens of people usually visit election committees to receive documents on the gubernatorial election. Holding both polls at the same time results in a huge amount of work for election workers.
