The unconstitutional disparity in vote values between the most densely and sparsely populated constituencies represented in the House of Councilors has dropped slightly to 4.77 times, according to a recent tally.
After the disparity grew to as large 5.00 times in the July 2010 Upper House election, the Supreme Court declared that the 2010 election was in a “state of unconstitutionality,” prompting the Diet to reform the electoral system last November.
To reduce the gap, two seats were added to two constituencies and two seats were eliminated from two other constituencies.
The tally by Jiji Press was based on voter registration lists released by the internal affairs ministry Thursday, when campaigning for the July 21 Upper House election officially kicked off.
According to the data, there were 104,780,660 eligible voters as of Wednesday. By prefecture,
Tokyo had the most, with 10,866,907 and Tottori had the fewest, with 483,734.
