Former champions Jubilo Iwata posted their first win of the season, beating Oita Trinita 2-1 in the J-League on Saturday.
Fabricio, one of their three new Brazilian players, dribbled through the Oita defence to score a game-deciding goal in the 82nd minute with a right-footed shot from near the edge of the penalty area.
Earlier, Norihiro Nishi put Iwata one up with a 68th minute header from Yoshiaki Ota's cross from the left, while Daisuke Takahashi levelled the scores in the 76th minute with a header from short range.
"Our goal for the day was to win. We did it. I felt that my players were determined to win after losing our opening game against Kashiwa last week," said Iwata's Brazilian coach Adilson Dias Batista.
"My players played really well in the first half. They showed a strong fighting spirit. That was the most important thing in today's game," he added.
Fabricio said he was pleased with his goal: "I thought I was able to do it alone. It was a good decision."
