While walking East of Shofukucho in Sotenbori, you'll find a group of people challenging Kiryu to a fight, with the restriction that only grabbing and throwing is allowed, of course it helps to have upgraded those, but the fight isn't too hard regardless.
After that, you'll be approached by Motoe Kawauchi, who comes with a request for you, to find and defeat his brother Gensho in the Coliseum. You'll find him in the Cataclysm Tournament, his style is Jujutsu, so cancel your selection and re-select the tournament until you see this, he's not too hard to defeat since he mostly tries using grabs.
After finishing the tournament, a cutscene will occur and returning to Motoe will grant you your reward!
