NPB park adjustments since 2011

Below are the park adjustments for runs and home runs for each of Japan’s Central and Pacific league teams since 2011, when Nippon Professional Baseball introduced a standard ball for the first time.

The big change this year was in Fukuoka, where the SoftBank Hawks, unable to replicate the team’s home run figures of 10-15 years ago, added field seats in left and right fields in front of the towering outfield walls at Yafuoku Dome.
