Speaking during the Tokyo Big6 Baseball League’s fourth week of play, the coaching staff noted that Yoshikai’s dedication to the team leaves little room for rest.
Early Mornings and Constant Vigilance Under Manager Horii
Manager Horii starts his days early, monitoring every detail for a roster containing 219 players. Ueda Masa, a pitching coach who joined the staff to support Horii, revealed that calls from the manager arrive as early as 5:00 a.m. to discuss pitching alignments. Amid this around-the-clock attention to the program, Horii admitted a persistent worry about his backstop’s well-being. “I worry about when Yoshikai actually gets to sleep,” Horii said.
Yoshikai, a fourth-year student from Keio Senior High School who locked down the starting catcher role last autumn, acknowledged his manager’s observation with a laugh. “I sleep just fine,” Yoshikai said. “Even so, I’m happy he feels that way.”

Resilience on the Field After Painful Bruising
Just a day prior, he absorbed a pitch to the right side of his face, leaving his right eye area heavily bruised with internal bleeding. Despite the injury, he played the full game behind the plate, demonstrating the grit that helped carry Keio through a dramatic turnaround.
Yoshikai served as the defensive anchor through that entire revival.
Prioritizing Teamwork Over Flashy Statistics
Yoshikai describes his playing philosophy simply as sweating for the team. “I don’t have any flashy standout points as a player,” Yoshikai said. “I just keep doing what I can—watching opponent video, paying closer attention to pitchers than anyone else, and stopping every ball. By keeping up these routine tasks, they eventually became my strengths. I think constantly continuing what I need to do has led to where I am now.”

Having filed his professional-registration paperwork on September 5, Yoshikai declined offers from corporate industrial leagues to pursue a career in Nippon Professional Baseball. He indicated a readiness to turn pro even if selected through the developmental draft rather than the primary rounds.
Yoshikai models his game after Hanshin Tigers catcher Seishiro Sakamoto. “I’ve spent my college career wanting to be a catcher who can lead the team to victory, rather than relying on power or a strong arm,” Yoshikai said. “My ideal is Sakamoto.”
