Compatriot Richie Gray did play in one of the Tests against the Qantas Wallabies, coming off the bench during the series clincher in Sydney, but has been selected among the replacements for the clash against Japan.
After Japan, Scotland face South Africa and Australia at Murrayfield and head coach Johnson insists every single place is up for grabs as they build towards the World Cup in two years time.
"We are looking to the future and we're also looking at people's futures too. This selection is a first chance for some to put their hand up," said Johnson.
"We have a 22-month campaign pre-World Cup and one of the mantras is 'this could be your last Test match'.
"It's not a right to play for your country. You have to go out there and perform. It's important that these guys who have got the jerseys go out and perform.
"Saturday is a good chance for the players to show their wares. Japan are well-coached, have a great work ethic and really good knowledge of rugby now."
