Mini bio
How it started.
Roki grew up in Iwate, Japan. The 2011 earthquake and tsunami took his father and grandparents and swept away his family home. After moving to Ofunato, he played baseball at his new school. He chose Ofunato High School to stay with his teammates, then drew attention with a fastball clocked at 101 mph.
A patient path to the mound.
Chiba Lotte won his draft rights in 2019 and held him out of games in 2020 to protect his arm. His NPB debut came in 2021. On April 10, 2022, he threw a perfect game against Orix, striking out 19 batters, including 13 in a row. Fans can watch the Marines’ own behind-the-scenes video of the celebration.
From Japan to Los Angeles.
He represented Japan at the 2023 World Baseball Classic before joining the Dodgers in 2025. His first MLB season brought a Tokyo debut, a first win and a move into postseason relief. He finished the year as a World Series champion.
