Tokyo, Aug. 4 (Jiji Press)–Fifteen constituencies in Japan’s House of Representatives had vote-value disparities of over two times compared with the least populated electoral district as of Jan. 1, up sharply from a year before, Jiji Press estimates showed Wednesday.

 

Last year, six electoral districts in the lower chamber of parliament had vote-value gaps above two times, marking the first time that the disparity exceeded the level since a drastic redrawing of the electoral map in 2017.

 

The No. 1 constituency in Tottori Prefecture had the smallest population, at 274,046, while the No. 22 constituency in Tokyo had the largest population, at 560,962.
As a result, the weight of a single vole in the Tottori No. 1 constituency was 2.047 times greater than that in the Tokyo No. 22 constituency. Last year, the maximum disparity was 2.016 times.

 

The estimates are based on resident register data from the internal affairs ministry.

 

The Tokyo No. 9 constituency, which had the largest population last year, was the second most populous electoral district this year, followed by the No. 15 constituency in Kanagawa Prefecture, the No. 13 constituency in Tokyo and the No. 6 constituency in Hyogo Prefecture.

 

The same districts made up the five most populous constituencies in 2020 as well.

 

Meanwhile, Tottori’s No. 2 constituency was the second least populous district, followed by the No. 4 constituency in Fukushima Prefecture, the No. 5 constituency in Hiroshima Prefecture and the No. 3 constituency in Tochigi Prefecture.

 

The Council on the House of Representatives Electoral District is drawing up redistricting plans on the basis of preliminary data from the 2020 census, released in June, which found 20 constituencies with vote weights topping twice that of the most populous constituency.

 

In the House of Councillors, the upper chamber, the vote-value disparities stood below three times for all prefecture-based constituencies for the third consecutive year.

 

Fukui Prefecture had the smallest population per lawmaker, at 379,430, while Miyagi Prefecture had the largest per-lawmaker population, at 1,129,781.

 

The vote-value gap between the two prefectures came to 2.978 times, up from 2.967 times a year earlier.

 

The vote-value gap stood above two times for 21 constituencies, including 2.963 times for Kanagawa and 2.920 times for Tokyo.
