Further behind, most eyes were now on Tsukakoshi, who was having an outstanding race from ninth on the grid, gradually picking his way through the order in his Manor Motorsport car. Passing Asmer on the restart, Tsukakoshi set about chasing down Oshima, achieving his goal on lap 13 with a move at Lisboa.
Seemingly the fastest driver on the circuit, Tsukakoshi did not have the time to launch an attack on Jarvis, finishing an otherwise excellent second behind Jarvis by 1.7secs.
The biggest win of Jarvis' career and also a significant victory for Toyota over their usually dominant Mercedes-engined competitors, it is the second consecutive British win in the race after Mike Conway in 2006.
Jarvis now joins the likes of Alexandre Premat,
Takuma Sato,
Ralf Schumacher and
David Coulthard in carving his name in history.
Behind Tsukakoshi and Oshima, British Champion Asmer had to settle for fourth position, the Estonian not quite living up to his early weekend pace when it mattered. With Prema's Roberto Streit in fifth, it also meant that four of the top five would be representatives of the Japanese Championship.
Sam Bird earned the mantle of finishing as the top Macau rookie for Carlin, while James Jakes emerged as the best of the Euroseries contingent in seventh place.
Pre-race favourite Romain Grosjean recovered to an impressive eighth after coming from the back of the grid, a feat that was matched by Edoardo Mortara and Sebastien Buemi in 10th and 11th, the trio separated by ninth place Stephen Jelley in the leading entry for reigning champions Double R Racing.
