SOUTH WILLIAMSPORT, Pa. (AP) -- Noriatsu Osaka hit three homers and tripled, and Japan limited Tennessee's potent lineup to two hits in a 12-2 victory Sunday in the Little League World Series title game.

Starter Kotaro Kiyomiya struck out eight in four innings and added an RBI single for the boys from Tokyo. The game ended in the fifth after Osaka's third homer made it a 10-run game.

A day after pounding out a 24-16 win over California in the U.S. title game, the Goodlettsville, Tenn., sluggers could only muster two hits -- solo homers by Brock Myers and Lorenzo Butler.

The teams exchanged the customary postgame handshakes at the plate before Japan received the World Series championship banner.
