Yoshinori Watanabe (?? ??, Watanabe Yoshinori, January 5, 1941 – December 1, 2012) was a yakuza, the fifth kumicho (chairman or Godfather) of the Yamaguchi-gumi, Japan's largest yakuza organization.
He became kumicho in 1989.
He was known for a more low-key approach than his predecessors, partly due to an anti-gang law passed in 1992.
