Why is it necessary to reduce the number of seats in the House of Representatives? And why should the amount of the reduction be 10%?
It must be said that the Japan Innovation Party’s argument is really lacking in persuasiveness.
The Liberal Democratic Party has established a political system reform headquarters directly under its president. The headquarters will formulate a plan to reduce the number of lower house seats, which was included in the LDP-JIP coalition agreement based on the JIP’s strong demand for the reduction.
JIP leader Hirofumi Yoshimura has said, as the reason for reducing the number of seats, that it will be impossible to achieve bold reforms on such matters as social security systems if “self-sacrificing reforms” are not carried out.
Within the JIP, many voices argue that 50 seats should be cut from the proportional representation........
