Woods expects the Phoenix Country Club course to present some new challenges when the tournament begins Thursday.
'The rough is higher this year than I've seen it the three other times I've played here,' Woods said Wednesday. 'It will be a very difficult test, but I'm really looking forward to teeing up to see if I can win this title again.'
Woods is coming off a second-place finish last week in the European tour's HSBC Champions in China, ending his stroke-play winning streak at six.
A winner of two majors this year, Woods said the key to winning in Japan will be consistency.
'Last week, I had two good rounds and two indifferent rounds,' he said. 'In the two indifferent rounds, I made too many silly mistakes. Hopefully, I can play well on all four days this time.'
The field includes Ireland's Padraig Harrington, who won the European Order of Merit title for the first time last month, and England's David Howell, third on the European Tour rankings.
Japan's Masashi 'Jumbo' Ozaki won the tournament three straight times from 1994-96.
