Floyd Mayweather says he doesn't really miss fighting yet and is looking forward to expanding his brand through business.

The former five-division and 12-time boxing world champion is currently visiting Japan to form "TMT Tokyo" and establish a partnership between his newly-announced Mayweather Holdings, Japan's Kyoei boxing gym and Japanese management company Libera.

Speaking at a news conference on Monday, Mayweather described a wide range of business fields including luxury car sales and the operation of nightclubs, boxing gyms and casinos.
