Japanese fighting game otakus are reportedly in shock that Korea won the gold medal.

‌
The talent pool of electronic game otakus in Japan is much larger than in Korea.
These are elite gamers who have been nurtured by Japan's Bandai for a long time,
but they are reportedly in shock because Korean "working adult" men took the gold medal.
They had great pride in Japan being the home of fighting games, but they lost to working professionals in their 40s.
It is a shock similar to when professional baseball in Korea loses to Japanese industrial baseball, where players also hold regular jobs.
