The Ryukyu Golden Kings claimed their first B. League championship with an 88-73 win over the Chiba Jets on Sunday.
The Okinawa-based team completed a 2-0 sweep of the best-of-three finals at Yokohama Arena a day after winning Game 1 96-93 in double overtime.
Guard Koh Flippin had a team-high 21 points and eight assists off the bench for the Golden Kings, while center Jack Cooley contributed 19 points and 15 rebounds.
Jets guard Yuki Togashi led all scorers for the second straight game with 24 points to go with six assists.
Ryukyu's raucous traveling fans once again created a home atmosphere inside the stadium, where their team erased unhappy memories of last year's 2-0 finals loss to Utsunomiya Brex.
"This stadium looked just like Okinawa Arena," Ryukyu head coach Dai Oketani said in his postgame interview.
Oketani said the Jets, whose league-best 53-7 regular season included a record 24-game win streak, were "without a doubt the strongest team this year."
"For us to win, we needed to play to 100% of our ability. The players really stuck to the game plan," Oketani said.
