Magic Murray sets up Nadal final in Tokyo
Murray, coming off his third title of the season in Bangkok last week, looked razor-sharp in shooting down Ferrer to set up a dream final for tournament organisers.
"I tried to be aggressive off the first ball of the rally and not let him dictate too many points off my serve," he said.
"I played smart and was hitting the ball very clean from the back of the court. It should be a great final against Rafa. He's always tough."
It is Murray's 13th win in a row and his 22nd in 23 matches, his only defeat in that time coming to Nadal in the US Open semi-finals.
The first set saw Murray control proceedings from the baseline as he forced enough errors from Ferrer to break the Spaniard twice while never dropping more than a point on each service game.
The world number four started the second set perfectly, breaking his opponent to love to take charge immediately. Murray held comfortably from then on and, with Ferrer serving to stay in the match, the Briton broke him again to love to set up a dream final.
