South Korean football coaches express concern over developmental gap with Japan

South Korean football coaches have expressed significant concern regarding the technical gap between South Korean and Japanese youth players. Ahead of the K League International Youth Cup 2026 in Incheon, media reports indicate that local instructors view Japan's Kashiwa Reysol youth team as a benchmark and a primary challenge.

Ulsan HD manager Lee Seung-hyun noted that South Korea is lagging behind Japan, particularly in fundamental technical skills rather than just superficial aspects of the game. Other coaches, including Gwangju FC's Park Johan, reflected on past matches against Japanese sides, noting the high level of composure and skill displayed by younger Japanese players.

This sentiment follows recent tensions regarding youth competition. After South Korea defeated Japan 1-0 in the men's football final at the 2026 Asian Games, Japanese media highlighted age differences and military service incentives as factors in the result. South Korean media dismissed these claims as excuses, arguing that teams should adhere to tournament regulations regardless of age composition.
