TOKYO, March 7, 2008 (AFP) - Japanese driver Kazuki Nakajima vowed Friday he would aim to collect points in every race in his first full Formula One year, but he knows it won't be easy.

"It's my goal to finish in the points in every race," Nakajima, who will partner German Nico Rosberg at Williams this year, said here ahead of the season-opening Australian Grand Prix at Melbourne on March 16.

"Of course it won't be easy to get points in every race. But if I seize upon the chances that must present themselves each time, they'll lead me to points. That's my goal," the 23-year-old added.

Nakajima made his F1 debut with Williams at the season-closing Brazilian Grand Prix last October after serving as the team's test and reserve driver earlier in the year. The chance came when Alexander Wurz announced his retirement from racing two weeks before the showdown at Interlagos.

Nakajima finished 10th in the race and Rosberg came in fourth to finish the season ninth overall with Finland's Kimi Raikkonen winning the drivers' title in a dramatic overtaking of Briton Lewis Hamilton at the last round.

Nakajima admitted it would not be easy to climb the F1 podium.

"Our machine has definitely improved from last year. I understand the margin of improvement and how other teams have got better," he said.

"As a team, we may still have many shortcomings as we aim for a victory or a place on the podium," he said. "To achieve the goal, it will depend on how much the team and myself can grow up this season."

Nakajima, the 2007 Rookie of the Year in the GP2 series, F1's feeder championship, said it would still be difficult to beat Ferrari and McLaren.

"The top two teams will no doubt go first with about five other teams trailing in a free-for-all," Nakajima said. "I will wait and see how far I can go out there."

Nakajima is the son of Satoru Nakajima, who was the first regular Japanese F1 driver and raced for Lotus and Tyrrell in the mid-1980s and early 1990s.

His Williams teammate is also the son of former F1 champion Keke Rosberg of Finland.

The junior Nakajima made his debut in kart racing in 1996, graduated from Toyota's training programme in 2002 and finished fifth and third overall in Japan's F3 series in 2004 and 2005 before challenging the European F3 series.

"Physically and technically, I believe I have reached the levels required (for F1 drivers)," he said. "About the problem of physical strength, I have felt good through simulation in test runs. In technical aspects, I have had a full grasp of each and every test through lap times."

"I know it is going to be an awesome season the whole year."
