Dice K did not do well but tanaka, darvish, iwakuma, maeda and uehara did quite well.
Maybe they do adjust better now and teams have found better protocols.
Will be interesting to see how otani does. If he stays healthy which is always a big issue for pitchers and moreso japanese pitchers I expect him to be a CY contender. He was more dominant than tanaka and darvish and 100 is 100. Health is a risk though.
What is interesting is that since matsui and ichiro no successful hitter came from japan. Even Korea did better in the last 10 years than japan with hitters. Maybe it is the combination of body size and the old school put it in play philosophy. Korean players tend to be a little bigger and they are swinging for the fences.
Will be interesting if japanese baseball adapts to the new hit it hard in the air and do not care if you miss philosophy, it seems like japan is slow to change in these things.
