Nippon Professional Baseball in Japan has long been considered the second-best league in baseball. Five players from the NPB transitioned to the MLB this past offseason: Yoshinobu Yamamoto, Shota Imanaga, Yuki Matsui, Yariel Rodriguez, and Naoyuki Uwasawa. Although injuries have plagued some, these players have transitioned exceptionally well to the MLB.

Shota Imanaga has been the most consistent and the best player to transition from the NPB to the MLB. Imanaga has pitched the most innings out of all Cubs pitchers and has the lowest ERA on the Cubs with a 3.06. The Japanese pitcher has an impressive 9-2 win-loss record in 21 starts. The 30-year-old left-handed ace has been a terrific acquisition for the Cubs due to his production and reliability.
Yoshinobu Yamamoto was the highest touted NPB player who came to the MLB. Expectations were sky-high for the right-handed Japanese pitcher when entering the MLB because he had won three Pacific League MVPs in the NPB. Yamamoto signed with the Dodgers this offseason, but his rookie season has not gone as he had hoped. The 25-year-old NPB superstar has been sidelined for over two months due to a strained rotator cuff. However, in his limited innings of work, Yamamoto has been terrific on the mound, boasting an impressive 2.92 ERA, 1.07 WHIP, and a 6-2 win-loss record.
Yuki Matsui signed with the San Diego Padres this offseason and has pitched serviceable innings in relief. Matsui is one of the four relief pitchers on the Padres to have under a 3.20 ERA. The 28-year-old left-handed pitcher has a 3.14 ERA and a 1.17 WHIP. In Matsui’s last seven appearances, he has been nearly unhittable, giving up zero earned runs and boasting an impressive WHIP of 0.55. If the Padres can obtain a wild card spot, Matsui will be an exceptional option as a high-leverage reliever come playoff time.
This past offseason, the Toronto Blue Jays signed Yariel Rodriguez out of the NPB. The 27-year-old Cuban starting pitcher has a below-average win-loss record of one and four but still has impressive statistics this season. The right-handed pitcher has a 3.86 ERA and a 1.33 WHIP this season for the Toronto ballclub. Additionally, Rodriguez has more strikeouts than innings pitched this season.
Naoyuki Uwasawa has not had the ideal start to his MLB career. After leaving the NPB and joining the Boston Red Sox this past offseason, the 30-year-old Japanese pitcher has only appeared in two games and pitched four innings. Although the right-handed pitcher has looked great in his limited innings of work in the MLB, having a 2.25 ERA and a 1.00 WHIP, Uwasawa and the Red Sox were both hoping he would have far more major league activity by this time of the season. Although Uwasawa was terrific on the MLB roster, he has struggled immensely on the Worchester Red Sox, Boston’s triple-A affiliate. The Japanese pitcher has an ERA over seven in triple-A ball and does not look like he will be called up anytime soon.
Overall, the pitchers joining the MLB from the NPB have been extremely effective and worthwhile signings for their new ball clubs. Because of these ex-NPB pitchers’ success in the MLB, it is reasonable to assume that MLB teams will continue to look to Japan for off-season pitching acquisitions.
