Although Scotland captain Greig Laidlaw is happy with his side's win over Japan, he admitted that his side can still improve.
Scotland secured a hard-fought 26-13 victory in Tokyo on Saturday but were made to work hard as Japan led 10-9 after 30 minutes.
Laidlaw admitted that Japan proved difficult opponents but said he was delighted with his side's fightback.
"It was good, it was a good win for us," he told the BBC.
"We were pleased to win and we probably need to just tighten up a little more and be a little bit more accurate.
"At times in the second half we just gave the ball away and maybe let Japan off the hook. But it was a tough Test match and credit to Japan."
Scotland beat Japan 45-10 when these sides met at the Rugby World Cup in England last year and Laidlaw said the Brave Blossoms were more competitive on Saturday.
"The scoreline was closer and they are improving all the time, and that's a credit to the players and the coaches," added the Gloucester scrum-half.
"They're a good team but also for us as well, we've not played together for a long time, and we will also look to improve for next week."
