Born on June 17, 1991, Kikuchi has built a notable career across both Nippon Professional Baseball and Major League Baseball. He previously played for the Saitama Seibu Lions in Japan, followed by stints with the Seattle Mariners, Toronto Blue Jays, and Houston Astros. Known for his powerful left arm and distinctive delivery, Kikuchi continues to be a prominent figure in international baseball.
A three-time NPB All-Star and 2017 Pacific League ERA leader, Kikuchi has earned recognition for his performance on the mound. He signed a three-year contract with the Los Angeles Angels in late 2024 and remains an active contributor in the major leagues. His journey from a highly touted high school prospect in Japan to a veteran MLB pitcher reflects years of dedication and perseverance.
Early Life and Background
Yusei Kikuchi was born on June 17, 1991, and grew up in Japan, where he developed a passion for baseball at a young age. He attended Hanamaki Higashi High School, the same school that future MLB star Shohei Ohtani would later attend. During his high school years, Kikuchi established himself as one of the most promising young pitchers in the country, demonstrating remarkable velocity and composure on the mound.
As a high school pitcher, Kikuchi’s fastball was clocked at 154 kilometers per hour, drawing widespread attention from professional scouts. In late 2009, he sparked considerable discussion when reports suggested he might bypass the Japanese amateur draft and sign directly with a Major League Baseball team. Several MLB clubs, including the Texas Rangers and Boston Red Sox, expressed strong interest in signing the young left-hander. Ultimately, Kikuchi decided to stay in Japan and enter the NPB draft, honoring the structure of Japanese professional baseball.
Path to Baseball
Kikuchi’s path to professional baseball was marked by intense scrutiny and high expectations. His decision to enter the Japanese draft rather than pursue an MLB deal immediately set the stage for his career with the Saitama Seibu Lions. He helped lead Hanamaki Higashi to strong finishes in national tournaments, including a runner-up position at the national high school invitational. His high school performances solidified his reputation as a top-tier pitching prospect in Japan.
In October 2009, Hanamaki Higashi manager Hiroshi Sasaki submitted paperwork on Kikuchi’s behalf to allow professional teams to contact him. This move opened the door for NPB teams to pursue him in the draft held later that month. Kikuchi was widely projected to be a top selection by multiple Japanese clubs. His choice to remain in Japan ensured he would develop within the structured Nippon Professional Baseball system before eventually making the leap to Major League Baseball.
