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.
Kanji Nukui became the six generation president in 1994. In October 2009 following Nukui's retirement, Makoto Suehiro succeeded Nukui, becoming the president of the seventh generation Goda-ikka.
Since 1996, the Goda-ikka has been a member of an anti-Yamaguchi federation named the Gosha-kai, along with three other Chugoku-based organizations, the Kyosei-kai, the Kyodo-kai, the Asano-gumi, and the Shikoku-based Shinwa-kai.
