Scotland sealed a late 21-16 victory over Japan with four straight penalties to complete a 2-0 series win in Tokyo on Saturday.
It was a difficult start for Scotland as they struggled to get going after Henry Pyrgos opened the scoring with a third-minute penalty.
Japan capitalised on their opponents' shaky display when fly-half Yu Tamura converted a penalty, and from that moment on, the team took a stronghold of the match.
Kaito Shigeno scored the first try of the game after getting released by Amanaki Mafi, who was part of of a break-out led by Riyika Matsuda.
Scotland had an opportunity to pull back the scoreline with a penalty, but Pyrgos failed to make the most of it as his kick from distance drifted wide of the sticks.
The Scots wasted another opportunity when Stuart Hogg sent the ball long into the corner for a lineout, but Stuart McInally's throw came to nothing.
After a slow start to the second half, Japan, who were playing in front of a record crowd of 31,392, extended their lead when Tamura knocked over a penalty, but Scotland eventually responded.
The team were given a penalty of their own following a forward charge, and Greig Laidlaw managed to convert before later scoring another to put the team one point behind their opponents.
After a handful of missed chances from Japan, Laidlaw dramatically put Scotland ahead by converting a 40-metre penalty and later extended their lead to wrap up the series win.
