Hideshima detailed a demanding schedule combining macro-managed nutrition, continuous training habits, and an athletic history spanning outfield play and catching duties.
Hideshima Maintains Strict Physical Conditioning and Nutrition
Hideshima wakes up to a precise physical maintenance routine that leaves no room for hesitation. Travel does not interrupt his conditioning; he reported that even standing on observation decks triggers involuntary training movements, and his evening routine often involves doing planks while trying to fall asleep.
Nutrition receives the same meticulous oversight. Hideshima maintains a daily intake of protein and green juice (aojiru) for breakfast and lunch. His evening meals consist of rotating portions of meat sauce, pudding, and cream puffs, with every calorie strictly monitored to support his athletic demands.
Baseball Career Evolution from Outfield to Catcher
Hideshima traced his baseball roots back to the autumn of his third year in elementary school, when he began playing as an outfielder. He humorously noted a defensive slump in the sixth grade where he lost the ability fly balls, joking that his nickname from that era could be the Kanto Plain number one goalkeeper. Through middle school, his game relied entirely on heavy swings and extra-base power.
He became an average hitter while attending Aoyama High School. Inspired by professional player Yanagita, Hideshima initially focused solely on full swings before realizing his bat-to-ball ability had sharpened significantly. During the summer of his first year in high school, he recorded 21 hits in 34 at-bats, compiling a .617 batting average that included nine consecutive games with hits and three straight games with four or more hits.
After a two-month break from club activities, he noted that rumors inflated his career average closer to .700, though he estimates his actual high school career average stood slightly above .420. During his second year of high school, he transitioned to playing catcher. This position brought back memories of his elementary school days in Singapore, where he spent slightly over a year and won a local softball championship as a catcher. That renewed experience helped him rediscover his enjoyment of the sport.
Transition to Saga and Collegiate Defenses
Following high school graduation and an unsuccessful university entrance examination, Hideshima moved to Saga Prefecture to live with his grandfather. During a period of independent study (takurō), part-time work, and travel, he developed a deep affection for the prefecture.
Returning to competitive baseball in college proved demanding, particularly on defense. Hideshima referenced the Pacific League’s recent Nippon Series statistics, noting that player Shuto’s UZR (Zone Rating) stood at 16.93, a metric measuring how many runs a fielder prevents compared to an average player. Assessing his own defensive capability by comparison, Hideshima estimated his current UZR at roughly -50, establishing a personal benchmark of aiming to bring that figure up to zero.
The Quest for a Ten-Heralded Batting Average
Reflecting on his ultimate athletic ambition, Hideshima stated that his primary goal remains unchanged since high school: achieving a 100 percent batting average, or a literal 10-wari hitter in Japanese baseball terminology. He aspires to become a batter who accepts any pitch without complaint and successfully hits everything thrown his way.
