Samoa got their 2012 Pacific Nations Cup campaign off to a winning start on Tuesday with a 20-18 victory over Tonga at Nagoya's Mizuho Park.
Samoan fly-half Ki Anufe scored two penalties while Tonga's Kurt Morath had three as Tonga led 9-6 at half time.
The Samoans got off to a flying start after the break with scrum-half Nalu Tuigamala scoring a try only two minutes into the second half to take the lead 11-9. Anufe made it 13-9 with a conversion.
Morath closed the gap to only one point with another penalty two minutes later but skipper David Lemi consolidated Samoa's lead with a try in the 49th minute for 18-12 and Anufe completed the scoring with a conversion.
Morath, who added two more penalties, had a chance to catch up with Samoa towards the end of the second half, but his attempts at a penalty and a drop goal went wide.
