Chris Harris came off the bench as Scotland hammered Russia 61-0 to set up a do-or-die showdown with Rugby World Cup hosts Japan on Sunday.
Gregor Townsend's team needed to take maximum points from their clash with the Bears in Shizuoka today to give themselves the best possible chance of making the quarter-finals, and they did just that thanks to a stunning nine-try demolition job.
George Horne became the first Scottish scrum-half to score a hat-trick after Adam Hastings had put the Dark Blues ahead with a quick-fire early double.
George Turner, Tommy Seymour, John Barclay and Stuart McInally also scored in a resounding win which now leaves Scotland needing victory over Japan in Yokohama in four days' time to seal their place in the last eight.
Carlisle-born centre Harris, who qualifies to play for the Scots through his grandmother, came off the bench midway through the second half to earn his 13th international cap.
