John Brake gave England the lead in the first-half, but they struggled to tame their opponents who levelled through Miguel Lucas' try before half-time.
A further try from Brake and one for Tom Mitchell eventually secured the match.
There was no such sluggish start from Scotland, who raced into a 19-0 lead over Japan with tries from Chris Dean, Andrew Turnbull and Michael Fedo.
Japan fought back late on, but two missed conversions cost them the game.
