A single seat, decided on plurality. Saki Nakayama holds 28.9% against 27.7% for the nearest rival.
Why KAN voters lean toward Yuko Yamazaki over Yuko Takahashi. Each driver is signed: + = lift, − = drag. Drivers are relative within this list and only move the persuadable slice of each party's vote, so their real effect is small. Coattail rows are direct share tilts in %. A raw vote lead does not equal the sum of these bars.
Ceiling this cycle: at most 20.0% of Yuko Takahashi's vote can be persuaded across to Yuko Yamazaki, and 20.0% of Yuko Yamazaki's vote can be persuaded away. Registration lean sets the starting split and how hard a party is to move, not the final share. These drivers add up to 0.2 pts of that movable slice.
