The points placing at Suzuka was the first time the Williams driver had claimed a top-10 spot since his superb maiden victory at the Spanish Grand Prix in May.
Since that success the 27-year-old has been hit with numerous penalties for incidents with his rivals, including a clash with Lewis Hamilton in Valencia and taking out Sergio Perez in the British Grand Prix at Silverstone.
Technical problems have also played their part in frustrating the Venezuelan, but having finally ended his points drought, he is looking for more of the same at this weekend's Korean Grand Prix.
"I think we can do well," he said. "Especially in qualifying I hope to be better (than in Japan).
"We know where the problem was and it is always difficult because the gaps are so close.
"In qualifying one or two tenths of a second is the difference between Q1 and Q2.
"The aim for us is to get to Q3 as I am very strong there and if we have the pace we had in the race in Japan then we can do well."
And Maldonado believes a repeat of his Barcelona win is not out of the question over the final five races of 2012.
He said: "Everything is possible, why not? We were so close in Singapore to being on the podium, but we had an issue with the car, but it could happen.
"We must stay together as a team when we have these kind of problems, we have not lost confidence in ourselves, we are getting stronger.
"It is a circle, I have had bad times and now it is back to normal which is good for the team and myself."
And he insisted far from feeling relief after getting some points on the board, he is ready to exercise the annoyance he felt during his nine-race absence from the top 10.
"It is not a relief, more frustration as we have been doing quite a good job, even after Barcelona," said Maldonado, who is in negotiations with Williams over a drive in 2013.
"We made a couple of mistakes but not always from my side, we had technical problems with the car and lost a lot of points. It was a combination of many things and we missed the chance to score some important points.
"We have always been competitive so I never lost confidence in myself and the team, the potential is good and we have now showed our consistency."
