Investigative reporting centers on Chen Zhi, chairman of Cambodia-based Prince Holding Group, who allegedly bought a Tokyo luxury villa in Suginami with cash and resold it to another Chinese buyer a month later; the group is cited by U.S. and U.K. authorities as among Asia's largest crime organizations for online fraud and human trafficking, while expanding its footprint in Japan by establishing three affiliates and listing Chen's address in Kita-Aoyama. Sanctions were imposed in October 2025, Chen was detained in Cambodia and handed to China in January 2026, and the group's core bank has been dissolved; the purpose of its Japan entry remains under scrutiny.
