And now he plans to take that to the Mercedes-Benz Arena and get the second-bottom club out of the danger zone.
"They expect me to be combat ready. I want to score goals and help the club remain in the first division," said Okazaki, who was an integral part of Japan’s Asian Cup-winning squad.
"I could score only three goals in one match in the tournament. There is still a lot of room for me to grow."
Besides helping Stuttgart achieve positive results, he is also keen to bypass the benchmark set by fellow Japan stars Keisuke Honda (CSKA Moscow) and Yuto Nagatomo (Inter Milan on loan from Cesena) who are performing well in Europe.
"I don't want to be outdone by them (Honda and Nagatomo). In Germany, I want to gain the skill to set up goals for myself," he added.
