Inside centre Matt Scott is "massively excited" for Scotland's Rugby World Cup campaign to begin after waiting five days for their first match.

Scotland face Japan in Gloucester on Wednesday with Vern Cotter's men one of four teams yet to taste World Cup action in England.

Scott conceded he struggled watching almost every other nation get started over the weekend, while the 25-year-old experienced Japan's shock win over South Africa like a "fan".

But his focus has now completely switched to his World Cup debut.

"It's been tough watching game after game and I'm just waiting to get out there," Scott said, according to The Scotsman.

"I must have replayed the game in my head about 100 times. I've thought about every scenario, so I'm massively excited.

"You can see the quality from the first few games and the excitement around every game. I can't wait to sample that.

"You can see the quality from every team has gone up, I don't think you are going to see the 140-0 score you may have seen in previous tournaments. Every team is competitive and you can see the month or so the teams have been together has brought the standard up."

Scotland will face the tournament darlings at Kingsholm, with Japan having hogged the World Cup spotlight since their 34-32 victory over the Springboks on Saturday.

Scott also got caught up in the "rugby classic" but claims it also confirmed that Cotter's pre-match preparations to face the Brave Blossoms were well thought out.

"It's been a while since I've been that emotionally involved in a game," Scott said.

"I was really rooting for Japan just in the way a neutral fan would. I was rooting for the underdog and it was a fantastic end to the game.

"We had one eye on our game against them as well and our analysis of the Japanese has been spot on. We expected them to have a quick ball out of the scrum, pick and go around the rucks and you saw from the first line break they had there was quick ball out the scrum and pick and go.

"At the end, in my head I was going, 'go for the try, go for the try!' It was really funny. I got really emotionally involved in the game, just as a rugby fan, because I think that game will be remembered for a long time. It's a rugby classic."
