Tenshin Nasukawa has touched down in Las Vegas -- and he's now at Floyd Mayweather's private boxing gym to show off his fighting skills for the media.
Floyd is also at the gym and after 20-year-old Tenshin holds an open workout, both guys are expected to address the media. TMZ Sports will be live streaming from inside the facility.
Of course, Floyd and Tenshin are set to throw down in Japan on New Year's Eve in a 3-round exhibition as part of the RIZIN 14 event at the Saitama Super Arena just outside of Tokyo.
