日本維新會
Following on from the LDP landslide win at the 2012 general election, in which the party won 12 of the 13 electorates in Shikoku plus two of the six seats from the PR list, the LDP maintained their dominant position in the region by retaining all 10 of their electorates (two electorates were abolished to address voter malapportionment) and gaining a seat on the PR list from the dissolved Japan Restoration Party (JRP).
