Ranking gap is the story

Japan sit 26 places above Tunisia in the FIFA ranking (#18 vs #44) — a gap of that size is hard for the underdog to close in a one-off match. Japan comes out at 41%, Tunisia at 31%, with the rest on the draw. Combined upset-or-draw chance keeps this one flagged as Upset Watch.
