I think the Japanese batters were even more shocking

I think they are a level above Taiwan
In the game against Taiwan, the fact that they couldn't hit Gwak Bin's pitches was just because Gwak Bin was at a disaster level, so even then
the batters behind him couldn't attack him
But Japan, with players like So Hyeong-jun, Kim Jin-uk, Park Byeong-hyeon, and Park Young-hyeon, etc.
they were consistently getting hits, which really surprised me
