Scotland have received a major boost in their tour of Japan with their lock Richie Gray is set to join the squad on Monday ahead of the two-match series against the Brave Blossoms.
Gray was released by Scotland to play for Castres and following the Top 14 club's defeat to Montpellier in the wild-card play-off, the 26-year-old will return to his international duty.
He is expected to begin his training on Tuesday and Scotland assistant coach Matt Taylor revealed that the management will have a hard look at him before announcing the squad on Thursday.
"He is looking forward to it," said Taylor, as the team prepared for their first training session since arriving in Tokyo.
"We have not named the team - we will wait to see what mental and physical shape he is in. He has been very good for us lately so depending on how he turns up will determine whether he comes in to consideration.
"Today's training is not a full-on session in terms of a lot of the contact, more about organisation. We have a hard session on Tuesday, when the bulk of the work will be done, and we hope he [Gray] will be involved in that."
In the World Rugby Rankings, Scotland are placed ninth while Japan after being toppled by Fiji has moved to 11th.
Japan stunned the rugby world with a majestic 32-34 victory over the Springboks in the 2015 Rugby World Cup encounter, but suffered a 45-10 defeat against Scotland in the next game.
The Asian team defeated Canada by 26-22 at the weekend in Vancouver which will aid their preparations leading to the series against Scotland.
Taylor said that the Scotland squad has been shown the video footages of Japan's recent game over Canada to help them analyse their opponent.
"We have seen it over and are going over it in a bit detail," he said. "It is similar to how the Sunwolves have been playing, they are quick to contact, they try to play a high-tempo game.
"There are a few similarities to how Japan played in the World Cup in some of their shapes and that they are trying to keep the ball in hand. They are kicking a wee bit more than they have in the past, so whether they keep that up we are not sure.
"Japan is only one ranking place below us, a very good side. We want to play well and put a marker down.
"We will be looking to go out there and win the game and put in a performance. I imagine both teams will be better for running together the second time around, we will be looking to play well and win."
The first Test between Japan and Scotland has been scheduled to be played on 18th June at the Toyota Stadium followed by the second game on 25th June at the Ajinomoto Stadium.
