In 1992, Andy Hug switched to Seidokaikan. This was a Japanese martial arts organization that focused on full-contact karate. Hug had been competing in K-1, a kickboxing organization, but he decided to switch to Seidokaikan because he felt that it was a better fit for his style of fighting. He remained with Seidokaikan for the rest of his career, and he won several championships in the organization.
