More Japanese players are playing in Europe now than in 2010 World Cup when they surprisingly went to the Round of 16 and almost to Quart Finals. Using this as a measurement I would say Japan is definitely one of the countries that moved the quality of its players forward on average. I would say they have more quality players for this world cup than any other. But the question is are they prepared for the world cup. Have the same players been playing together, or do they have a coach who was doomed to fail from the beginning?
