This question depends on how we compare them. I don’t think it is possible to say in a general way which one is stronger, and I think the comparison of the same period should be meaningful. For example, you ask the French football team in 1998 and the Italian football team in 2006 are incomparable. America must be better than Japan? I don’t think so. Baseball is not just about comparing the individual abilities of every player. The pitcher’s schedule, the arrangement of playing line, the time of changing players and the coach’s tactics will affect the final success or failure. In terms of Strike ability, Japanese players are generally slightly inferior to American players, but Japanese player Ichiro Suzuki ranks first in the Major League every year and is stronger than most American players. In 2009, Hideki Matsui won the key competition almost alone with his outstanding strike performance in the world competition. As for pitchers, the best Japanese pitchers in the major leagues are basically the first tier pitchers in the major leagues, such as Darby Hugh and Tanaka. So in terms of personal ability, I don’t think the gap between the two sides is enough to determine whether one side will win. According to the ranking released by the World Baseball Association, Japan has been at the top of the list since 2014, while the United States ranked first from 2009 to 2012. This ranking is calculated by converting the ranking obtained by the national team in various international competitions into points, and its fairness is sufficient. If the current ranking of Japan is not true for various reasons, then the previous ranking of the United States is likely to be false.
