Tries from Kotaro Matsushima and Yoshikazu Fujita helped them into an 18-8 half-time lead, with Takudzwa Ngwenya crossing for the US.

Amanaki Mafi burst through for Japan's third try before Chris Wyles crossed to give the United States hope.

But Goromaru's third penalty late in the game gave Japan a clear lead.

After their thrilling opening win against South Africa, Japan went on to add the scalps of Samoa and the US, but their heavy defeat by Scotland left them third in the group, and they miss out on a place in the last eight.

The Eagles finish having lost all four of their matches.
