Japan pulled off the biggest shock in the history of the World Cup with their win over South Africa in Brighton on Saturday.
However the tournament has had its fair share of surprise results, with World Rugby putting together a top five of the biggest shocks in the competition's history.
There are three big upsets featuring the pacific islands teams, including Western Samoa's surprise success over Wales back in 1991, and Fiji's win over the same opposition 16 years later.
Tonga's pool success over France four years ago also cracks the list, as does les Bleus' stunning semi-final success in 1999, arguably the best game the tournament has ever produced.
But it's fair to say none can top the effort of the Brave Blossoms last weekend, as they confounded expectations with their last-gasp success against the Springboks.
