Japan picked up their second win of the 2023 Rugby World Cup, beating a 14-man Samoa 28-22 on Thursday, which gives their knockout hopes a boost.
With Argentina expected to claim five points against Chile over the weekend, the Brave Blossoms will then face Los Pumas in a winner-takes-all showdown.
This result at the Stadium de Toulouse means that England will finish as Pool D winners due to their head-to-head record against both Japan and Argentina.
Samoa are subsequently out of the running for the knockout stages, with this their second defeat out of three games ahead of facing England on October 7.
Japan, who reached the last eight for the first time four years ago as hosts, opened the scoring in the 13th minute when Lappies Labuschagne stretched over in the corner and Rikiya Matsuda converted.
A penalty from D'Angelo Leuila got Samoa, without captain Chris Vui through a late change, on the board, but Matsuda's kick soon restored Japan's advantage.
Michael Leitch added another try in the corner before Samoa's Jonathan Taumateine was sent to the sin bin after a shoulder barge in the build-up.
Japan hooker Shota Horie was then shown a yellow card for making head-on-head contact as he stood up in a challenge with Seilala Lam, which went to the TMO for a bunker review but was not upgraded.
Samoa ― whose final pool match with England is in Lille next weekend ― made the most of their man advantage, Lam touching down following a driving maul to go into the break trailing 17-8.
Samoa soon found themselves a man down when Ben Lam was sent to the sin bin after the TMO spotted a high tackle into the side of Labuschagne's head.
Japan extended their lead as Kazuki Himeno was driven over in the corner, but the usually reliable Matsuda failed to convert.
Things then got worse for Samoa when Lam's card was upgraded to a red before Matsuda again found his range to push Japan further in front at 25-8.
Kotaro Matsushima sprinted clear for what Japan thought was a bonus-point try, but it was ruled out for the slightest of knock-ons from Dylan Riley in the build-up.

Samoa, though, kept themselves in touch as Duncan Paia'aua went over in the corner, which Leuila converted from a tight angle only for fly-half Matsuda to push Japan clear again with another long-range penalty.
The 14 men battled on and pulled the deficit back again when Christian Leali'ifano dived over and then converted his own try, but Japan held out to set up a potential winner-takes-all clash with Argentina in Nantes.

The win puts the South Americans level on points with New Zealand in Pool A, who they face next Thursday, although the All Blacks have a game in hand.
Wales were outstanding as 23 points from replacement fly-half Anscombe, who came off the bench after Dan Biggar's injury on 12 minutes, floored Australia.
The maximum haul puts the Scots on five points ahead of facing Romania before their Pool B campaign ends with a mouth-watering match against Ireland.
It was a captivating 80 minutes at the Stade de France as both sides threw everything at each other, with the Irish prevailing against the 2019 champions.
The success leaves Steve Borthwick's outfit on 14 points in Pool D, with one game remaining against Samoa on October 7 as they look to wrap up top spot.
In an enthralling encounter, Portugal came from 13-0 behind to launch a stunning fightback as they held an 18-13 lead before Tengizi Zamtaradze scored a try in the game's dying moments to clinch the draw for the Lelos.
The rain didn't help but there was little entertainment and attacking quality on show, with Los Pumas grinding out a vital win in the race for the knockouts.
It was a record victory for Les Bleus as they cruised to a bonus-point success, with 54 points racked up in the opening half and 42 in a second in a canter.
The Uruguayans were much the better side in the first half and deservedly went 17-7 ahead at the interval through Nicolas Freitas' score, a penalty try and Felipe Etcheverry's drop-goal.
The famous win throws Pool C wide open as the islanders move on to six points, level with Australia and four behind Wales with two matches still to play.
It was far from pleasing on the eye but the Red Rose got the job done as they backed up their opening triumph over Argentina with a bonus-point success.
As the scoreline suggests, this was a one-sided affair as the defending world champions dominated from start to finish and eventually ran in 12 tries with Cobus Reinach and Makazole Mapimpi crossing for a hat-trick apiece.
Tougher tests await in South Africa and Scotland but on the evidence of their opening two matches, Andy Farrell's men look in fine shape.
The Portuguese were impressive throughout and caused their opponents numerous problems, but the greater quality eventually told.
Tries late in the first half and several in the second were enough to keep a brave Chile side at bay despite their best efforts.
It was one-way traffic in the Pool A clash as the All Blacks ran in 11 tries on the night, with Damian McKenzie adding a further 16 points off the tee.
The game in Lille was predicted to be a comfortable result for Les Bleus but it was anything but as Los Teros will view this as a match they could have won.
The Fijians came agonisingly close to recovering from 32-14 down with just seven minutes remaining, but a knock-on from Semi Radradra ended their fight.
