The Belarusian, who was left in tears after losing to Serena Williams at Flushing Meadows earlier this month, said she has turned her focus to the $2.17 million title in a strong field, including Maria Sharapova and Agnieszka Radwanska, the world numbers two and three.
"I am looking forward to starting this tournament," the 23-year-old top seed said. It features 19 of the top 20 seeded players, with just fourth placed Serena Williams absent.
When asked whether her physical and mental fitness has improved since the New York tournament, the Australian Open winner responded: "I don't think so. It's been too quick."
She added: "It was a great tournament for me, the US Open. It was so close. I had a great experience there, absolutely no regrets. But I cannot wait to play these last tournaments as well as I can."
Crowd favourite Sharapova, the French Open winner and silver medallist at the London Olympics, will be looking to avenge her US Open semi-final defeat to Azarenka and win back the title she held in both 2005 and 2009.
"To be back here... healthy and as the number two in the world, (I am) really looking forward to it," she said.
Radwanska returns to the Japanese tournament as the defending champion, after reaching her first Grand Slam final this year at Wimbledon, where she also lost to Williams.
Petra Kvitova, the 2011 Wimbledon champion and world number five, also said she will be looking to regain the form she showed earlier in the year when she reached the semi-finals of the Australian and French Open.
Chinese star Li Na and two compatriots are also in Tokyo despite tensions between China and Japan that have seen players pulling out of badminton and table tennis competitions citing safety fears.
While Japan-China ties have soured over a territorial row in the East China Sea, Li's more immediate worry will be her fitness.
The 30-year-old has a cold, an organiser said. Only three weeks ago Li said she needed to take a break from the sport after a shock defeat to British teenager Laura Robson at the US Open.
