Voters who participated in the election cast one ballot for the proportional block and a separate ballot for one of the 13 smaller single-member districts that are located within Shikoku.
Results
Prior to the election, the ruling Democratic Party of Japan (DPJ) held three of the six PR block seats as well as 5 of the 13 small electorates that make up the block. The opposition LDP held 2 of the PR seats and the 8 remaining electorates, while their traditional junior coalition partner Komeito held the final PR seat.
The 2012 general election delivered a landslide victory to the LDP, with 294 of the 480 seats won at the national level. The election decimated the DPJ from a pre-election position of 230 to just 57 seats.[1] In the Shikoku PR block, the DPJ lost 2 of their seats as their vote was reduced to 16.0%, down from 43.2% in the 2009 election. Junya Ogawa lost his seat in Kagawa 1st district but was the DPJ candidate to suffer the narrowest defeat, so he was able to retain a seta in the house. The newly-formed Japan Restoration Party gained the two seats lost by the DPJ.[2] In the 13 single-member electorates, the LDP gained 4 seats, with Yuichiro Tamaki being the only DPJ member to retain his seat in the Kagawa 2nd district.[3]
