ONE Championship Stacks Legendary ONE 173 Card in Tokyo

The ONE 173 main event delivers a clash for the ages, as reigning ONE Featherweight Kickboxing World Champion Superbon looks to cement his divisional supremacy against interim titleholder Masaaki Noiri in a unification bout.

Superbon faces Japan’s homegrown hero in what promises to be a technical masterpiece between two of kickboxing’s most accomplished champions.

The Thai striking legend’s reign has been defined by his technical brilliance and finishing ability, while Noiri captured interim gold to position himself for this opportunity. The unification clash represents the pinnacle of ONE Championship’s featherweight kickboxing division, determining the undisputed king.
