Susumu Kajiyama

is a retired yakuza best known for his arrest in 2003, who was dubbed the "loan shark king". He has been introduced as a senior member of the Shizuoka-based Goryo-kai, a secondary organization of Japan's largest yakuza syndicate, the Yamaguchi-gumi, although he was technically not a member of the Goryo-kai.

Career He began his career as a yakuza after graduating from middle school, when he met the head of the Suzuki-gumi, an Inagawa affiliate, in jail. He joined the Suzuki-gumi and founded a yamikin organization in Shinjuku, Tokyo, launching his underground financial business.

He left the Suzuki-gumi in 1997 and along with his elementary school senior Yasuo Takagi, he joined the Shizuoka-based Mio-gumi, a tertiary organization of the Yamaguchi-gumi. In August 2003 he was arrested for violating the investment law by "supervising moneylenders providing loans at unlawfully high interest rates".

Involvement in politics In August 2003, Shizuka Kamei, then a senior member of the ruling Liberal Democratic Party and former Senior Superintendent of the National Police Agency, acknowledged receiving political donations from Kajiyama.
