(CNN) -- World number one Rafael Nadal has reached the semifinals of the Japan Open in Tokyo, but the tournament's second seed Andy Roddick is out.
Top seed Nadal beat Russia's Dimitry Tursunov 6-4 6-1 in just 72 minutes in Thursday's quarterfinal, despite having been a break of serve down in the opening set.
The Spaniard will next face Serbia's Viktor Troicki, who put out Guillermo Garcia-Lopez -- Nadal's conqueror in last week's Thailand Open semifinals.
"It's good for the confidence to keep winning after taking an important title like the U.S. Open," the 24-year-old Nadal told the official ATP website.
"When I go on court and I see a full stadium like here today, it is very nice. It is good for everyone".
