Japan's Kazuki Nakajima has vowed to find a way back into Formula One after his final hope of securing a drive in the 2010 season was dashed.
Serbian-backed Stefan GP were refused entry by the sport's governing FIA as a late replacement after USF1 failed to make the grid, leaving the former Williams driver out in the cold.
'With Stefan GP not gaining approval my plans are unclear. I will continue to work to find a way back to the world level,' Nakajima told his official website.
Nakajima's failure to secure a seat this season leaves BMW Sauber's Kamui Kobayashi as the only driver from Japan on this year's Formula One grid.
Honda's former poster boy Takuma Sato switched to IndyCar racing last month after being snubbed by Toro Rosso, Renault and the new Malaysian-backed Lotus team.
Nakajima remained positive despite the setback and added: 'That's the nature of the sport. I will keep looking forward and spend some time below the surface keeping busy and concentrating on how to secure a quick return.'
