Tokyo, Aug. 5 (Jiji Press)–Six constituencies in Japan’s House of Representatives had vote-value disparities of over two times against the least populated electoral district as of Jan. 1, Jiji Press estimates showed Wednesday.

The vote-value disparity in the lower chamber of parliament topped two times for the first time since drastic electoral reforms in 2017.

The No. 1 constituency in Tottori Prefecture had the smallest population, which totaled 276,281. The No. 9 constituency in Tokyo had the largest population, at 557,071.

As a result, the weight of a single vole in the No. 1 Tottori constituency was 2.016 times greater than that in the No. 9 Tokyo constituency. Last year, the maximum disparity was 1.990 times.

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

The vote-value gap with the No. 1 Tottori constituency exceeded two times also for the No. 13, No. 16 and No. 22 constituencies in Tokyo, the No. 6 constituency in Hyogo Prefecture and the No. 15 constituency in Kanagawa Prefecture.

The maximum disparity was less than two times in the 2017 Lower House election thanks to the electoral system reform.

The Lower House plans to reallocate seats to better reflect regional population differences, after a national population census scheduled for October this year.

In the House of Councillors, the upper chamber, the vote-value disparities stood below three times for all prefecture-based constituencies, as they did last year.

The constituency in Fukui Prefecture had the smallest per-lawmaker population, at 382,398, while the constituency in Miyagi Prefecture had the largest, at 1,134,388.

The vote-value gap between the two constituencies came to 2.967 times, up 0.011 from last year.

The disparity with the Fukui constituency topped two times for 21 constituencies, unchanged from last year.
