June 22, 1936 - Masaru Takumi
As the top financial architect of Japan's most powerful yakuza organization, he shaped how the Yamaguchi-gumi operated as a criminal enterprise — consolidating influence and revenue across the country's underworld for decades. His assassination in 1997, carried out at a hotel in broad daylight, was significant enough to trigger a major internal crisis within the syndicate.
