Blue Boy Trial

2025 106 min Japanese K-12
Wubly rating 6.9 IMDb rating 6.9

1960s Japan—economic boom, Olympic pride, and a crackdown on “public morals.” An anti-prostitution law targets women but spares male sex workers, the so-called “blue boys.” When police arrest the doctor performing their sex reassignment surgeries, the sensational “Blue Boy Trial” begins. Three transgender women take the stand, igniting a national debate on identity, medicine, and happiness—long before the language of LGBT existed. Though the court ruled surgery legal, the verdict cast a shadow: no such operations would occur in Japan for 29 years. Half a century later, this buried history still reverberates in the lives of sexual minorities.
