From 1983 to 1998, the vote in the proportional district of the House of Councillors had to be for a party, lists were closed. Since the 2001 election there is the option to cast a preference vote for a single candidate instead, the vote then counts for both the party in the allocation of proportional seats to party lists, as well as the candidate in the ordering of party lists. From 2001 to 2016, the system was a most open list system: The ranking of candidates on a party list strictly followed the number of preference votes. This ranking also applies to the runner-up replacements in case of vacancies.
In the 2019 election, the proportional district is enlarged to 50 members; and the proportional election system is modified to no longer be fully open: In a so-called ''tokutei-waku'' (特定枠, literally "special frame") parties may now choose to prioritize certain proportional candidates, such protected candidates can no longer be elected personally, but always come first in the allocation of proportional seats.
