Position players Munetaka Murakami and Kazuma Okamoto as well as pitcher Tatsuya Imai are the three biggest free agents coming out of Japan this offseason, but Murakami is far and away the headliner. Despite the fact that he's experienced a lot of regression since his 2022 season (when he hit 56 home runs), he looks like he could be a Pete Alonso-esque bat in MLB if the right team can fix him up. He's also four years younger than Okamoto.
Murakami is a corner infielder but seems destined to become a full-time DH, which is basically a non-starter for the Tigers.
