While each party exchanged opinions at the House of Councilors Constitutional Research Committee regarding the "joint district" of the election district held in the Upper House election, the LDP argued that the constitution should be amended to eliminate the "joint district". The Constitutional Democratic Party argued that there was no need for a constitutional amendment, saying it was possible.
At the House of Councilors Constitutional Research Committee on the 18th, each party exchanged opinions on the "joint district" targeting Tottori and Shimane, Tokushima and Kochi, which are being held in the Upper House election.
In this, Haruko Arimura of the Liberal Democratic Party said, "Prefectures have played an important political and economic role. The Liberal Democratic Party has listed the dissolution of the joint ward as one of the four items of constitutional amendment." He said that the constitution should be amended to eliminate the "joint district".
In response, Mr. Hiroyuki Konishi of the Constitutional Democratic Party said, "I am against the constitutional amendment to abolish the joint district. Based on the role of the House of Councilors, we should discuss the abolition of the joint district by amending the law." He expressed the idea that there was no need to amend the constitution.
On the other hand, the Komeito and the Nippon Ishin no Kai called for the nationwide constituencies to be changed to block units by region instead of prefectural units in order to correct the one-vote disparity. The Komeito argued that the electoral system centered on proportional representation should be reviewed.
