Australia A exploded for nine tries en route to a 63-5 romp over Japan's national XV in a friendly match on Thursday.

The visitors raced to a 35-0 lead at Osaka's Nagai Stadium before fullback Toru Kurihara got Japan on the board with an unconverted try just before the end of the first half.

Australia A added four more tries in the second 40 minutes as the outclassed Cherry Blossoms got a hard lesson in running rugby ahead of this year's World Cup.

Australia A coach Adrian Thompson said he was happy with his side's performance in the first of two matches scheduled against Japan's national team.

"All the players had solid games," Thompson said. "In particular John Roe was very strong with the ball in hand, and Joel Wilson defensively in the midfield shut down a lot of their attacking plays."
