Team of the Week: Sons of the Rising Sun
Not only has the 34-32 triumph moved them to within one spot of a top-10 place on the world rankings, but they have three players in our Team of the week's starting XV.
Another three members of the Japan team have found spots in our back-up selection.
New Zealand, the world's top-ranked team, also have three players in our starting XV after their hard-earned win over Argentina.
Another minnow who has received recognition for their success at the weekend is Georgia - who occupy two places in the frontline selection.
Apart from the three Japanese players bubbling under, France and Argentina (three each) also recognised for their efforts.
Wales have two players bubbling under - while Samoa, England, Ireland and Italy have one each.
Team of the Week - World Cup, Week One:
15 - Ayumu Goromaru (Japan):
If you haven't heard of him before, take note NOW! One of the key players in the biggest upset in World Cup history.
Bubbling under: Tim Nanai-Williams (Samoa)
14 - David Kearney (Ireland):
Part of a very powerful; and impressive Irish back three.
Bubbling under: Santiago Cordero (Argentina)
13 - Marcelo Bosch (Argentina):
Was up against the world's most astute outside centre and passed the test with flying colours.
Bubbling under: Cory Allen (Wales)
12 - Sonny Bill Williams (New Zealand):
Showed some ominous form.
Bubbling under: Juan Martin Hernández (Argentina):
11 - Nemani Nadolo (Fiji):
Fiji, at times, resembled a one-man show and Nadolo was it.
Bubbling under: Kotaro Matsushima (Japan)
10 - Jonathan Sexton (Ireland):
The world's premier flyhalf - the evidence is there for all to see.
Bubbling under: Kosei Ono (Japan)
9 - Aaron Smith (New Zealand):
There is something special about his game that you don't find in statistics - his ability to read the play and make the right decisions.
Bubbling under: Fumiaki Tanaka (Japan)
8 - Mamuka Gorgodze (Georgia):
Gorgodzilla put his imposing size and rampaging style of play on full display in a fine win.
Bubbling under: Louis Picamoles (France)
7 - Michael Broadhurst (Japan):
You have to wonder why the older brother of New Zealand international James Broadhurst was never called up to the All Blacks.
Bubbling under: Justin Tipuric (Wales)
6 - Michael Leitch (Japan):
He led from the front in a defiant show of strength.
Bubbling under: Thierry Dusautoir (France)
5 - Konstantine Mikautadze (Georgia):
Made an amazing 23 tackles - bettered only by his captain - and made a major contribution in the set pieces as well.
Bubbling under: Pascal Pape (France)
4 - Brodie Retallick (New Zealand):
Produced another world class second row performance.
Bubbling under: Geoff Parling (England)
3 - Rabah Slimani (France):
Made a mess of the Italian scrum and scored a crucial try.
Bubbling under: Mike Ross (Ireland)
2 - Agustín Creevy (Argentina):
The heart and soul of the Pumas' pack.
Bubbling under: Leonardo Ghiraldini (Italy)
1 - Ben Arous (France):
He gives the appearance of a grizzled veteran, but is still only 25.
Bubbling under: Tony Woodcock (New Zealand)
