Looking at the Japanese comments regarding Lee Jong-beom at Chunichi, the feedback seems quite positive.

The comparison to Korea's Ichiro might have set the bar too high,
but starting from comments like "He would have been a leadoff hitter on any team and would have recorded over 40 stolen bases,"
it seems people have good memories and impressions of his gritty, spirited style of play. There are also comments mentioning his contribution to their championship.
