Japan had to work hard in that first half but was just too good for the Russians with Kotaro Matsushima scoring a hat-trick of tries.
At the end they picked up the win and a bonus point to start their campaign beating Russia at the end 30-10.
It was Russia that put huge pressure on the host from the kick-off forcing a lineout which they got a penalty from. Although they did not get any points from it they still kept the Japanese in their own half.
From a kick down field Russia kicked it back and a mistake from Japan gave Kirill Golosnitskiy the first try of 2019 World Cup.
Japan answered back the best possible way in speeding up the game and got to send Kotaro Matsushima over the line.

The conversion was not over so that left Russia still leading 7-5 after 12 minutes.
Russias have come to the match to play and although it looked like they were getting out of steam they stayed in the match counter attacking each time they got the ball in hand.
Japan was also making some ordinary mistakes and poor judgement on attack kicking the ball away with some players on the outside to spread it wide.
It was a struggle for Japan but after a disallowed try Kotaro Matsushima he got over for his second just before halftime.
This gave the Japanese a well deserve lead going into the break.
