Russia sneaked into the Rugby World Cup after Romania and Spain were disqualified for multiple eligibility breaches during qualifying for the competition as they fielded ineligible players.
The Bears are ranked 20th in the world and run out to face the hosts, Japan, in the opening match of the Rugby World Cup.
Ahead of the opening game Russia head coach Lyn Jones said Russia have 'tripped' into the Rugby World Cup, leaving them at a disadvantage against hosts Japan.
"We've basically fitted four years' work in one year. It comes with many challenges and inconsistencies but we're learning on the go.
Speaking ahead of the fixture Jones said that Monday, Tuesday and Wednesday would be key for his side in training:
"The next three days are more about tactical appreciation, and the last day is more mental because for players, not just Russian players but any player in the world in the game of rugby union, it doesn’t get a bigger game than this, at the World Cup.
"There is nothing you can do to prepare players for it, they have to experience it. They should be proud to represent their country on the big stage."
Jones went onto say that Japan would provide a big test for his side as Jamie Joseph's side plays a fast-paced game that his side is not used.
"Russia has a lot of really good players but we are preparing for a game that’s 20-times faster (than we are used to)." he told the media at Urawa Royal Pines Hotel on Sunday.
"The pressure is going to be strong on us, the game is going to be so physical and so fast. Japan are going to put speed on the game, and we need to be so concentrated, single-minded and so focused on what’s happening on the field. We need to put the crowd out of our sights, don’t even worry about what’s going on off the field.
"Every focus, every step, every second, keep your eye on the ball and never turn your back on the opposition, constantly creating pressure, taking time away from the opposition and continuing to put pressure on players."
