For the Aussies, Cayla Francis was dominant, finishing with 20 points and 18 rebounds, while Marianna Tolo added 22 points and six rebounds.
Japan’s Azuso Sato was the stand-out, finishing with 21 points, including five three pointers.
The Aussies were unrelenting, dominating the game from the get-go, taking a 31-12 quarter time lead, thanks to the combined efforts of Penaluna, Hunt, Bishop and Francis.
The Aussies would then build on that lead at every change, ultimately taking the big 60-point win into their third match-up of the tournament tomorrow with a great deal of confidence.
The Aussies dominated the glass, winning the rebound count by a whopping 62-20, which included 23 offensive boards. They shoot 56 per cent from the field, which included a scintillating 70 per cent from beyond the arc, which the Japanese side struggled to find an answer for.
Head coach Phil Brown was rapt with the win, with the team now turning their attention to the Czech Republic after securing a 2-0 tournament start.
“We had 11 scorers in the game and to out-rebound Japan 63-20 was just a huge effort,” he said. “And having kept our foul-count down, we were able to keep Japan away from the foul line, which helped us also limit their outside shooting,” he said.
The Australians now face the Czech Republic tomorrow at 8pm (AEST) in their third match up in the group stage.
Australia 113 (Tolo 22, Francis 20) def Japan 53 (Sato 21, Kayoko 13)
