For the second game in as many days, the Akita Northern Happinets topped the century mark in points.
Richard Roby and Shigehiro Taguchi both scored 23 points on Sunday, leading the Happinets to a 101-94 home victory over the Niigata Albirex BB.
Roby was 9-for-12 from the field in a splendid shooting performance. Taguchi drained 6 of 10 3-pointers as Akita improved to 32-8, including 17-3 at home. The Eastern Conference leaders, led by third-year bench boss Kazuo Nakamura, clinched a playoff spot.
