Naoya Inoue will face the biggest challenge of his stellar career when he takes on fellow unbeaten countryman Junto Nakatani on Saturday in front of a sellout crowd of 55,000 at Tokyo Dome.

Undisputed super bantamweight world champion Inoue will defend his titles for a seventh time when he clashes with the dangerous southpaw.

They boast identical 32-0 records, setting the stage for a bout that has been more than a year in the making and been dubbed the biggest boxing match in Japanese history.
