Winging in: Ngwenya scored for the USA but they let Japan in two minutes later. (Photo: Getty Images)WHAT’S NOTUSA’s concentration – Both times the USA scored in the first half they conceded points to Japan immediately afterwards. Their fourth minute penalty was soon cancelled out by a sixth minute try for Japan and after Ngwenya scored his try with 25 minutes gone, they let Fujita through less than a minute after the re-start.End of the party – So that’s it, the pool stages of RWC 2015 are over, and only the eight quarter-finalists remain. The party which has raged from Newcastle to Exeter and all points in between will now be replaced by the more serious business of the knockout stages. It’s been a blast.

The Eagles took the lead with an early penalty but Japan hit back quickly with a try from Kotaro Matsushima. Takudzwa Ngwenya put the USA back in front after 24 minutes with a try, but again Japan countered with a score of their own from Yoshikazu Fujita, converted – like the first – by Ayumu Goromaru, who kicked a penalty to give Japan a 17-8 half-time lead.Try time: Kotaro Matsushima slides in for Japan’s first try v USA.

Pens: Goromaru 3.Referee: Glen Jackson (South Africa)Man of the Match: Ayumu Goromaru (Japan) WHAT’S HOTJapan’s half-backs – Fumiaki Tanaka and Kosei Ono work together as a pair so well. Sometimes so close to each other they are practically joined at the hip, they always keep opponents on their toes.Blossoms’ bravery – Japan came into this match knowing their quarter-final dream was over as Scotland were six points ahead of them in the Pool B table, but they still fought proudly to end the tournament on a high, coming back from behind twice and repelling several strong offensives from the USA.Andrew Durutalo – The USA openside won the most turnovers in the match, five, was joint top of the gain-line breakers with himself and Michael Leitch both crossing the line ten times, and he made 46 metres in attack.Glorious Gloucester – There was nothing but pride riding on this match, and it finished just shy of 10pm on a school night, but local rugby fans of all ages still packed Kingsholm’s stands and terraces to ensure the USA and Japan ended their tournament with a proper rugby send-off.
