Vern Cotter wants improvement from his Scotland team following their 21-16 test win over Japan.

Cotter's men failed to score a try in the second test in Tokyo but four late penalties from the boot of Greig Laidlaw ensured Scotland rounded off a long season with a narrow 21-16 victory.

"Everybody that came on, everyone who has been part of this tour brought something," Cotter said.

"The group is as tight as it could be. The tour has been different - the weather, the culture - there are a lot of differences. The team adapted well during the game but also everybody played their role within it.

"They were always going to be 23-man games and we knew we would be relying on the bench to come on and add that extra energy and hopefully wear them down.

"We will review the trip with total honesty. Performance is about consistency. We need to make sure we are out there and performing consistently.

"We are disappointed we lost ball and some of our plays did not come off as well as we would like them to have. I know players are disappointed but we will look at all that next time we come together.

"The next time we come together is November and I would like to think that the players from what has been a pretty big year will take time to look at the performance and the content of the performance as we did when we broke up last time.

"Our last game (before the tour) was the loss against Ireland - so some things are coming right.

"No coach is ever going to be totally happy and I know we will find parts we need to improve, we saw some of them here. It will be a focus next time we come together."
