Former four-organization world champion boxer Katsunari Takayama is trying to earn a chance to take a shot at another shiny reward.

Except this time, it's not a belt. It's an Olympic medal from the Tokyo Games.

But before he can step into the ring in pursuit of that goal, Takayama has to first become eligible to fight at the Summer Games, which are scheduled to be held in the Japanese capital in 2020.
