The Toyota Motors Alvark and Aisin Sea Horses are perennial powerhouses in the JBL, and as most people anticipated, the familiar names are the last teams standing.

The two clubs crash into the new-look JBL's best-of-five championship series, which tips off on Thursday at Yoyogi Gymnasium Annex.

The Sea Horses (26-9, first in the regular season) were 5-1 against the Alvark (21-14, second) in the regular season and they defeated the same opponent in the All-Japan Championships final in January.
