I saw the 2 games in this group and Japan was a team that impressed me a lot, they played against Germany, one of the favorite teams to win the competition and they made a solid and safe performance, especially in the second half. Coach was able to see what was wrong in the first half and in the second half his team was much better and won. For those who saw the game, the result was not as big a surprise as the victory of Saudi Arabia.
The truth is that if Japan wins, they will have 6 points and will be in a very favorable position to move on to the next stage and that is what is the biggest surprise because there are Spain and Germany in the group.
Morita is already good and should start from the beginning, Hiroki Sakai is doubtful.
Costa Rica is one of the weakest teams in this World Cup, they lost in their debut against Spain 7-0 during the game they showed nothing, there was no quality in the team and if Spain accelerated more they could have scored 10 or more goals.
From what I've seen of the team, i don't see how it's possible for Costa Rica to win a point in the group. Coach during these days is trying to give his players confidence to make a better performance.
There are no absences in the team.
Costa Rica have failed to score in 5 of their last 7 matches, in the last 7 games in World Cups they have not won. Costa Rica will do better than the last game, that's for sure but even so they don't have the quality to win or draw against Japan who are very motivated and confident. Japan will be the team that will have more ball and more opportunities and if they play like they did against Germany they will win the game.

我看了这个小组的两场比赛，日本队给我留下了深刻的印象，他们对阵德国队，德国队是最有希望赢得比赛的球队之一，他们打出了稳定而安全的表现，特别是在下半场。教练能够发现上半场的错误，下半场他的球队变得更好，赢得了比赛。对于那些观看了比赛的人来说，这一结果并不像沙特阿拉伯的胜利那么令人惊讶。
事实是，如果日本队获胜，他们将获得6分，将处于非常有利的位置，可以进入下一阶段。这是最大的意外，因为小组中还有西班牙和德国。
森田已经很好了，应该从头开始，酒井弘树是怀疑的。
哥斯达黎加是本届世界杯上最弱的球队之一，他们在首场比赛中0 - 7输给了西班牙，比赛中他们没有表现出任何东西，球队没有任何质量，如果西班牙能加快速度，他们可能会进10个或更多的球。
从我对这支球队的观察来看，我不认为哥斯达黎加有可能在小组中赢得一分。教练在这些日子里试图给他的球员信心，使他们有更好的表现。
球队里没有人缺席。
哥斯达黎加在最近7场比赛中有5场没有进球，在世界杯的最近7场比赛中他们没有赢过。哥斯达黎加会比上一场比赛做得更好，这是肯定的，但即使如此，他们也没有能力赢或平日本队，日本队非常有动力和自信。日本队将会有更多的球和更多的机会，如果他们踢得像对阵德国队那样，他们就会赢得比赛。
