New Book 'Why Can't I Speak Even When I Want To? The Mechanism Behind Why People Who Read the Room Lose Their Voice' to be Released on June 1st

JMA Management Center (JMAM), led by President Shiro Cho, will release the book 'Why Can't I Speak Even When I Want To? The Mechanism Behind Why People Who Read the Room Lose Their Voice' on June 1, 2026, at bookstores nationwide and online. The book explores why people often find themselves unable to speak despite knowing what to say, attributing it not to personality or ability, but to 'body' and 'non-verbal communication.' It explains the 'Freeze' mechanism—where one goes blank when called upon in meetings or loses words when observing a supervisor's expression—using psychology and neuroscience. By integrating his experience as an actor and corporate trainer, author Hiroyuki Hayashi proposes practical solutions based on improvisational theater (Impro). With over 10 years of experience and 10,000 participants in his training sessions, Hayashi provides insights that offer relief to those struggling to speak and a deeper understanding for managers regarding their subordinates' psychological states.
