NHK党が比例で1議席獲得すると社民党が0議席になる?

Original review summary

The review explains that House of Councillors proportional-representation seats are allocated using the D’Hondt method, so one party winning a seat does not by itself make another party lose one. The outcome would depend on the parties’ vote totals and whether they were competing for the final seat; the review says it could not be called almost inevitable in advance.[S1]
