Suzumiya is a minor antagonist featured in Yakuza 4.
In 2010, when Ueno Seiwa Clan captain Isao Katsuragi agrees to meet with Kazuma Kiryu atop Kamurocho Hills to negotiate for the release of his captives, the siblings Taiga and Yasuko Saejima, he decides to reduce the chances that Kiryu will beat him up when he arrives to the meeting. In order to do so, he orders all the men of the Ueno Seiwa Clan that he has available at the time to go to Kamurocho Hills and attack Kiryu as he makes his way up, in order to tire him as much as possible before the confrontation.
Suzumiya is the third of the Ueno Seiwa lieutenants that Kiryu encounters as he fights his way up the building. He awaits Kiryu at the shopping center's third floor in a men's suit shop, where he attacks Kiryu with a shotgun. Despite his heavy firepower, Kiryu manages to best him. He attacks Kiryu further down the same floor, this time next to the elevators that lead to the in-construction portions of the structure. This time he is accompanied by even more of his men, but despite this, he is still unable to stop his target from progressing.
Kiryu comes across Suzumiya for a final time in the penultimate floor of the building. There, all four lieutenants of the Clan gather to fight Kiryu together. Despite their combined efforts, they are beaten once again and Kiryu proceeds to confront Katsuragi.
Suzumiya uses a shotgun in combat, blasting at Kiryu when he gets close to him. If attacked while reloading, he will strike Kiryu with the butt of the weapon, which can easily stun him. Suzumiya will frequently dodge roll out of combos and shoot at Kiryu from the ground; an attack which can stagger the Tojo man. He cannot be grappled, as he will break out of any holds immediately unless a heat action is triggered as soon as he is grabbed.
