Former world No 1 and four-time Major winner Osaka was appearing at the competition for the first time since 2020 and won her opening singles game yesterday.
But she did not need to play a second time after Hibino clinched Japan’s spot in November’s finals with a hard-fought 6-4, 3-6, 7-6(9/7) win over world No 50 Yulia Putintseva.
Hibino fended off four straight match points for Putintseva before coming back to win the third-set tiebreaker.
It was the world No 79’s second singles victory of the tie after dispatching Anna Danilina 6-1, 6-0 in under an hour on the opening day.
Osaka beat Putintseva 6-2, 7-6(7/5) yesterday, hitting 15 aces and no double faults.
It was her first match in Japan since appearing at the Pan Pacific Open in September 2022.
Kazakhstan were without world No 4 Elena Rybakina, who lost in the final of the Miami Open last month.
The BJK Cup finals will be held in Seville.
