Japan have moved above their next World Cup opponents Scotland in rugby union's official world rankings.

The countries will meet in a Pool B clash at Gloucester's Kingsholm ground on Wednesday, just four days after Japan produced the biggest shock in World Cup history by beating two-time tournament winners South Africa.

The latest rankings list, published by World Rugby on Monday, shows that Japan have risen two places to 11th, with Scotland - who have yet to start their World Cup campaign - dropping from 10th to 12th.

South Africa, meanwhile, have fallen three places into sixth spot as a result of the 34-32 defeat against Japan in Brighton.

But World Cup hosts England, their Pool A rivals Wales and Pool D favourites Ireland have each moved up one spot into third, fourth and fifth, respectively.

And it means that three teams in the same World Cup group - Australia, England and Wales - now occupy the three places immediately below long-time rankings leaders New Zealand.

Further down the list, Georgia are rewarded for their 17-10 World Cup victory over Tonga by jumping three places into 13th.
