Campaigning officially started on July 3, 2009. The prefecture's 10.6 million registered voters (up 230,000 from 2005) were called upon to elect the 127 Assembly members in 42 electoral districts at 1,868 polling stations across Tokyo. 221 candidates had been formally registered with the Tokyo metropolitan electoral commission. The LDP and the Democratic Party of Japan (DPJ) each endorsed 58 candidates, the Japan Communist Party (JCP) supports 40 and New Komeito formally fields 23 candidates, though it has also decided to support LDP candidates in several districts. Local campaign issues included Tokyo's bid for the 2016 Olympic Games and governor Shintaro Ishihara's plan to relocate the Tsukiji fish market in 2012. The national debate over a possible ban of "hereditary" (, "seshū") politicians has also affected several candidates.
