* First Japanese to win Tokyo title
* Nishikori set to rise to 15th in rankings
* Japanese targets top 10 (Adds quotes, more details)
TOKYO, Oct 7 (Reuters) - Kei Nishikori stunned big-serving Milos Raonic 7-6 3-6 6-0 with an electrifying display of attacking tennis to become the host country's first Japan Open champion on Sunday.
It was the eighth seed's second career title after winning in Delray Beach in 2008 and will elevate the 22-year-old from 17th to 15th in the world rankings.
"I'm partying tonight!" Nishikori said in a courtside interview as a sellout Tokyo crowd went wild. "I'd thought the Gods were against me at this event in the past.
"To win the title is amazing. I'm overwhelmed.
"I don't know what I'm going to do with a year's worth of Corona beer," added Nishikori, sheepishly referring to a bonus gift from tournament sponsors. "I don't even like beer."
Nishikori took the first set tiebreak 7-5 after a jaw-dropping running backhand pass, clenching his fist to salute the roars of the crowd.
Sixth seed Raonic took the second, drilling a bullet serve at Nishikori's body as the cheers of the majority among the 13,000 centre court fans turned to groans.
However, Nishikori stormed back in the decider, ripping another fierce backhand pass down the line to open a 4-0 lead, leaving his Canadian opponent gaping in disbelief.
COUP DE GRACE
He delivered the coup de grace moments later, a lofted return forcing Raonic to smash a drive volley into the net after two hours, eight minutes to complete a final set 'bagel'.
"It's absolutely unbelievable to win in Japan," added Nishikori, $308,000 richer. "To win an ATP 500 event will give me more confidence in the future.
"I'd never played well in Japan but since beating (second seed) Tomas Berdych (in the quarter-finals), I felt I'd broken that wall down. To reach the top 10 is my target now," He told reporters.
Both players were presented with flowers by Australian Ken Rosewall, who won the title in 1973, the first year the Japan Open became an official tournament.
"Kei is a superstar in Japan," said Raonic, who shocked last year's winner and U.S. champion Andy Murray in the semi-finals and fired down 14 aces against Nishikori.
"I don't think I had a letdown after beating Murray," added Raonic, projected to rise one spot to 14th in the rankings.
"Kei is so quick and he was reading my serves well, which doesn't usually happen. I love coming to Japan and thanks Japan for inventing sushi. I love it." (Editing by Peter Rutherford)
