He tied Ren Nakata and Nao Higashihama for 5th in the WL in wins despite his limited time on the farm. He was 0-2 with a 3.19 ERA in 32 games for the 2014 Hawks (2-1, 2.41, .96 WHIP in 12 minor league games). In 2015, he had a 4.20 ERA in 16 games while also doing well in the minors (2-0, 3 Sv, 1.61.

By 2017, he was a regular for Softbank out of the 'pen, going 2-0 with 2.76 ERA as a LOOGY (32 2/3 IP in 58 G, fanning 47). He tied Yoshihisa Hirano, Kazuhisa Makita and Shota Takekuma for 7th in the PL in appearances. He retired four of five batters in the 2017 Japan Series, spread over four games; only Toshihiko Kuramoto reached against him. He tied for the team lead in appearances as they won the Series over the Yokohama BayStars. 
The slender southpaw went 2-1 with a 2.45 ERA and .85 WHIP in 67 games and 33 IP in 2018. He was 4th in the PL in outings, between Yuhei Takahashi and Yuito Mori. He excelled in the 2018 Japan Series, with one hit in 3 1/3 IP over five games (tied with Shota Takeda for the team lead) as the Hawks beat the Hiroshima Carp in six contests. 
He made Japan's squad for the 2019 Premier 12. Again a lefty specialist, he pitched one inning over three games for the champs! He debuted against Puerto Rico, relieving Rei Takahashi in the 7th with a 4-0 lead. He retired Danny Ortiz then Kan Otake took over. Against Team USA, he replaced Taisuke Yamaoka with a 3-1 deficit in the 5th, two on and two out and fanned Jake Cronenworth. Yudai Ono succeeded him to open the 6th.
