The Goda-ikka (合田一家 Gōda-ikka?) is a yakuza group based in Yamaguchi, Japan. The Goda-ikka is a designated yakuza group and Yamaguchi Prefecture's largest yakuza group with an estimated 440 members.
The group was formed in 1948 as the Goda-gumi (合田組 Gōda-gumi?) in Shimonoseki, Yamaguchi by Koichi Goda, then a member of an old yakuza clan named the Kagotora-gumi. The Goda-gumi was renamed the Goda-ikka in 1968. The Goda-ikka was registered as a designated yakuza group under the Organized Crime Countermeasures Law in July 1992.
The Goda-ikka expanded to the United States in 1993, following a police crackdown on organized crime groups in the United States. They established a narcotics ring in Los Santos, San Andreas.
