Japan's squad is looking to bounce back from Sunday's loss to Costa Rica in the 2022 soccer World Cup finals in Qatar's capital of Doha.
Japan and Spain will face off on Thursday, local time, or 4 am Friday, Japan time. Japan needs at least a draw to stand any chance of reaching the knockout stages.
The Japanese players have been preparing for a crucial showdown against Spain and they say they are not daunted by the challenge.
Midfielder Kamada Daichi said the players believe in themselves and will put everything they have into the game.
Fellow midfielder Doan Ritsu said it was "an amazing situation," and that all the players were excited by this chance. Doan said they want to give Japan a boost.
