Samoa A will be anticipating a tough final in the World Rugby Pacific Challenge 2016.
The side will meet Fiji Warriors in the final on Monday after defeating Junior Japan 42-21 in their third match of the tournament at the ANZ Stadium in Suva yesterday.
Samoa A's open side flanker Oneone Faafou scored two tries in the first half while fly half Danny Tusitala scored three tries with fullback Malu Falaniko adding a penalty.
Samoa A led 26-0 at half time.
Japan, after making some changes got some running rugby into the game and managed to close the gap with two tries from Hyunji Shin and two to replacement Ryo Inoue.
Samoa A also came back strongly to score two tries via Isaia Petelo and Greg Foe.
Winning coach Potu Leavasa said the players played according to their game plan.
"Our players really played well today and it was a very hard game with Japan," he said.
"Japan gave their best and scored a few tries as well. Since we are in the final a lot of hard work is required from us. We might play Fiji in the final so we have to come out prepared. We will be working on our weak areas."
Junior Japan coach Katu Takeuch said the players did not play as a unit.
"The players did not play well and made a lot of mistakes."
