Is Japan ahead of Korea in the field of sports?

Recently, Japan has gained attention for its impressive performance against Brazil in the World Cup. Watching this match, I became curious about whether Japan is widening the gap with Korea in sports overall. Japan is excelling not only in soccer but also in various sports such as baseball, wrestling, swimming, rock climbing, judo, gymnastics, volleyball, skateboarding, long-distance running, badminton, table tennis, and boxing. What could be the reasons for these achievements? I would like to hear your thoughts on what factors contribute to Japan's sports success and how Korea can analyze and improve in this regard. It seems that a deeper discussion is needed on whether differences in sports policies, training methods, and other aspects are influencing this situation.
