Early Career
Tsutsumi first laced gloves in junior high, copying his older siblings. A feisty amateur run—84 wins with 40 stoppages—earned him national podium finishes, but never a coveted crown.
That chip on his shoulder fueled his ferocious gym work at Heisei International University, where lectures were balanced by dawn roadwork and late-night bag sessions. By 22 he’d passed the Japanese B-class pro test and debuted at Korakuen Hall in March 2018, blasting Thailand’s Alongkon Kaisi in 91 seconds.
Three more quick knockouts followed, stamping him as a “pressure cooker” prospect. A 2020 majority-draw thriller with ex-flyweight champ Daigo Higa proved he could hang with world-level talent even before winning a single belt.
Professional Career
The momentum spiked in June 2022 when Tsutsumi dethroned Kyosuke Sawada for the Japanese bantamweight title, then bulldozed through three defenses in ten months. December 2023’s “Monster Tournament” final saw him floor Kazuki Anaguchi four times, pocket 10 million yen prize money, and book a world title shot.
On 13 October 2024 at Ariake Arena he overwhelmed Takuma Inoue over 12 high-octane rounds to claim the WBA crown.
Four months later his first defense against old rival Higa turned into a bloody classic—both men dropped in round nine, judges calling it a 114-114 draw. Eye surgery in May 2025 paused his march, yet the unbeaten champion-in-recess vows to return before year-end for a unification clash.

FAQs
1. What makes Tsutsumi’s fighting style stand out from other bantamweights?
His trademark is relentless pressure paired with sneaky switch-hitting. He crowds opponents with high-volume combos to the body, then flips to southpaw mid-flurry, forcing mistakes he punishes with looping hooks. The tempo rarely dips, making him a nightmare to out-work over 12 rounds.
2. How did Tsutsumi earn the nickname “Punch Burger”?
During college he ran a pop-up burger stall to pay gym fees. Friends teased that his patties were “as heavy as his punches,” and he added the moniker to his social handles. Fans now bring burger-themed banners to fights and he often grills for sparring partners post-camp.
3. Why is he listed as WBA champion in recess?
A deep cut suffered versus Higa required surgery, slowing his return beyond the WBA’s 120-day defense window. Instead of stripping him, the sanctioning body placed him in recess and elevated interim champ Antonio Vargas. Once medically cleared, Tsutsumi automatically becomes mandatory challenger for the full title.
4. Has Tsutsumi ever considered moving up or down in weight?
He walks around at roughly 132 lb, so dropping to super-fly is unrealistic. Super-bantamweight (122 lb) is viable, yet his team prefers conquering bantam first—namely unifications with WBC king Junto Nakatani and IBF/WBO titleholders—before testing the higher division.
5. What charities or community projects does Tsutsumi support?
Seiya regularly donates fight-night gloves and ring-worn trunks for auction to fund boxing gyms damaged by the 2016 Kumamoto earthquakes. He also sponsors annual amateur tournaments in his hometown, covering travel stipends so rural kids can experience big-city rings without financial strain.
