The reality for Adam Nawalka's side is very different, though, as following back-to-back defeats against Senegal and Colombia respectively, Poland are going home after Wednesday's match irrespective of the result.
Polish emotions are in stark contrast with those in the Japanese camp, where little was expected of Akira Nishino's side but they will book their place in the knockout stages with a win on Thursday afternoon.
The Blue Samarai are 6/4 (2.50) favourites with the same firm to book their place in the knockout stages.
Depending on the outcome of Senegal's clash with Colombia, a draw could see Japan safely through and dabblebet go 11/5 (3.20) that this match ends all square.
Kamil Glik came off the bench for the final 10 minutes of the defeat to Colombia and the commanding centre-back may be called upon as Poland look to restore some pride.
Keisuke Honda became the first Japanese player to score at three World Cups by netting as a second half substitute against Senegal and the veteran midfielder looks set to start his country's final group game.
Japan have kept just one clean sheet in their last 15 matches and goalkeeper Eiji Kawashima has made already a couple of costly errors already in this competition.
Nishino's side, however, have scored eight goals in their last three games and they will be confident of hurting a Polish side that have kept just one clean sheet in their last seven outings.
The 21/20 (2.05) quote from dabblebet for this match to produce at least three goals could prove popular, as every game played by either side this World Cup has seen over 2.5 strikes.
However, it is the 4/5 (1.80) price from the same firm for goals at both ends that may represent real value for punters ahead of Thursday's tussle.
