Samoa have overcome a slow start to avoid potential banana skin team Russia, claiming a 34-9 win at Kumagaya Stadium.
Trailing 6-5 at the break, Samoa came out of the sheds with a different mindset, scoring in the 45th minute through No. 8 Afaesetiti Amosa who was stretchered off with a leg injury.
Fullback Tim Nanai-Williams was involved all over the park and was many times the instigator for their attack.
Samoa's next try came off a lovely lineout play which saw winger Ed Fidow cruise in almost untouched after an inside ball from replacement Ray Niuia.
He would have a double four minutes later as the pace and execution of the Samoan's was too much for the European side.
Centre Rey Lee-Lo got in on the try scoring as he scored out wide off a good blackline move to free up the 32-year-old.
They continued to dominate until right winger Alapati Leiua scored his second after a powerful run down the wing.
Samoa: 34 (Alapati Leiua x 2, Afaesetiti Amosa, Ed Fidow x 2 and Rey Lee-Lo; Tusi Pisi two conversions )
Russia: 9 (Yury Kushnarev 2x penalty and one drop goal)
