Scotland captain and scrum-half Greig Laidlaw believes a change in game-plan will help his side to beat Japan in Tokyo on Saturday.
Last weekend, Scotland were made to work hard when the sides met in Toyota City and they eventually claimed a 26-13 win with both their tries scored while Japan had players in the sin bin.
And Laidlaw, who finished with a 16-point haul after slottting six penalties, believes a smarter approach will be needed against the Brave Blossoms this weekend.
"We'll need to make some small tweaks within the game," he told the BBC.
"That's the beauty or the hard part of playing teams back-to-back. You don't want to be doing exactly the same things one week to the next.
"The flipside to that is I'm sure Japan will try and change a couple of things too. Defensively, we'll need to be smart."
Scotland head coach Vern Cotter is expected to make several changes to his starting line-up.
The first Test's analysis revealed that Scotland ran 50 percent more in that fixture than a typical Six Nations fixture.
"It is a different game," added Laidlaw.
"The fact that we coped well and came out with a victory was credit to the boys, especially in the heat.
"Vern's right on the boys' heels about staying in system and getting to the ball carrier quickly."
