Aika Hirashita scored a game-high 17 points off the bench Thursday as Japan tipped off its FIBA Women's Basketball World Cup campaign with a comfortable 89-56 win over Mali.
Nanako Todo added 14 points and Stephanie Mawuli had 13 for the Tokyo Olympic silver medalist, which took control of the Group B clash at Sydney Superdome following a tight opening quarter.
World No. 37 Mali rebounded strongly and capitalized on second-chance opportunities to trail eighth-ranked Japan 21-18 at the first interval.
Coach Toru Onzuka's team found its rhythm in the second quarter and used its trademark fast transition game to pull away to a 47-29 halftime lead, with Hirashita leading the charge.
The 20-year-old small forward shot 6-from-9 from the field, including a stellar 5-from-6 from behind the three-point arc.
Former Seattle Storm forward Ramu Tokashiki, who missed the Olympics with an ACL injury, grabbed a team-high seven rebounds for Japan.
In other action on the opening day of the tournament, the three-time defending champion United States eased to an 87-72 win over Belgium in Group A.
The World Cup, contested by 12 countries divided into two six-team groups, runs through Oct. 1 in Sydney.
