"I'd be very confident that they (players) are aware of the high-tackle framework, and how it works."
Rolland's comments come after England coach Eddie Jones described the red card shown to All Blacks lock Scott Barrett for a tackle on Wallabies captain Michael Hooper last month as "ridiculous".
Jones said the sending off "lacked common sense" and that a lack of consistency around refereeing threatened to disrupt the World Cup.
Under the new guidelines, referees must confirm contact with the head first and assess level of danger as Rolland explained.
And while confusion has surrounded the role of TMOs in decision making, Rolland said their role remained unchanged in Japan.
"He's looking at serious acts of foul play, where he can assist match officials," Rolland said.
"(Otherwise) around grounding (the ball) around try time, there are other things that can be checked - forward passes, obstructions, offside."
