João Miyao was born on May 11, 1991, in Andirá, in the state of Paraná, Brazil, alongside his twin brother Paulo Miyao. Third-generation Japanese descendants, the brothers grew up in modest circumstances as the sons of a farmer and a housewife. Their introduction to martial arts came through Judo — a natural entry point for many Brazilian families with Japanese heritage — but it was Brazilian Jiu-Jitsu that captured their imagination when they discovered it at age 16.

Their first BJJ instructor, Adriano Carvalho, recognized the twins' potential early and pushed them to train and compete with increasing regularity. As their passion for the sport deepened, João and Paulo made a pivotal — and at the time controversial — decision: they would move to São Paulo to pursue professional BJJ careers, a plan their parents opposed. The brothers left Andirá anyway, betting everything on their capacity to compete at the highest level.

In São Paulo, the Miyao brothers found both a training home and a community at Cicero Costha's social project, the PSLPB — Projeto Social Lutando Pelo Bem (Fighting for Good Social Project). Living within the academy alongside other dedicated athletes, the brothers immersed themselves in jiu-jitsu with a totality that would come to define their identities. Their technical development drew heavily from studying the games of Rafael Mendes and Guilherme Mendes, whose sharp, flexible guard systems aligned closely with what the Miyaos were building.

The results at colored belt level were extraordinary. João accumulated gold medals across IBJJF World and Pan Championships at blue, purple, and brown belt — with wins at the 2011 IBJJF World Championship, 2012 IBJJF World Championship, and 2013 IBJJF World Championship at respective belt levels, alongside consistent Pan Championship dominance throughout those years. Perhaps even more striking was the brothers' ability to medal in absolute divisions while competing at just 64 kilograms, a testament to how effectively their guard systems neutralized larger opponents. That combination of technical distinctiveness and outsized competitive results attracted media attention and, ultimately, the sponsorships needed to compete on the global stage.

Although Paulo Miyao received his brown belt before João, the brothers received their black belts together in June 2013 — a symbolic culmination of a journey taken side by side from Andirá to the top of the colored belt world.

At black belt, João Miyao established himself as one of the most decorated competitors of his generation in the featherweight and light-featherweight divisions. His IBJJF No-Gi World Championship gold medals in 2015, 2017, 2018, and 2019 placed him among the sport's elite no-gi specialists, while his 2019 IBJJF World Championship gold in the gi confirmed that his game translated fully across both formats. Pan Championship dominance stretched from 2014 through 2018 — a five-year run that few competitors in any division have matched.

Beyond the IBJJF circuit, Miyao demonstrated his credentials across multiple global platforms. He claimed UAEJJF Grand Slam titles in Abu Dhabi, Rio de Janeiro, and Los Angeles, won the KASAI Pro 6 Grand Prix in 2019, and captured the ACBJJ 6 Grand Prix in 2017. His ability to perform across different rulesets and promotion formats revealed a grappling IQ that transcended any single competitive environment.

Even as Miyao began balancing competition with coaching and gym ownership, his competitive edge remained intact. In 2022, he took gold in the Master 1 division at the IBJJF World No-Gi Championship in the light-feather division, and he and Paulo Miyao shared the podium at major adult events as recently as the 2021 IBJJF Pan Jiu-Jitsu Championship — demonstrating that the passage of time sharpened rather than diminished his technical mastery.

Few names became more synonymous with the berimbolo revolution of the early-to-mid 2010s than the Miyao brothers. João's flexible, invertible guard game — built on seamless transitions between Berimbolo, inverted positions, and back-take sequences — became a defining aesthetic of competitive BJJ during that era. The style drew from the Mendes brothers' influence but evolved into something distinctly Miyao: faster inversions, tighter back-take entries, and a willingness to chain attacks through complex positional sequences.

Competing in absolute divisions at 64 kilograms, João demonstrated that the guard system was not a stylistic curiosity but a genuinely effective weapon against athletes of all sizes. The berimbolo, once viewed with skepticism in certain quarters, gained mainstream acceptance in part because competitors like Miyao were using it to win at every level of the sport's most prestigious events.

Underpinning all of it was a work ethic that became the stuff of legend within BJJ circles. Miyao reportedly drilled techniques for hours on end during his climb through the ranks and at times slept on the gym floor rather than interrupt his training schedule — a monastic commitment to craft that shaped both his technique and his identity within the sport.

As João Miyao's black belt career matured, a new signature emerged from his already formidable technical arsenal: the Baratoplata. By 2022, the submission had become his most identifiable finishing weapon — that year, he secured ten baratoplata submissions in tournament competition alone, a volume that illustrated both his belief in the technique and the depth of his setup work.

Mechanically, the baratoplata shares structural similarities with a Triangle Choke in terms of limb control and leverage principles, but it demands exceptional flexibility, precise timing, and a sophisticated understanding of how body positioning creates and removes escape routes. João has noted in instructional content that control and positional dominance precede the finish — the submission is not a gamble but the natural consequence of having established a superior position.

The technique benefits notably from gi grips, which aligns directly with João's stated preference for gi training. In a January 2026 Instagram interview, he explained his orientation plainly: "Gi, for sure. I have more options. It's more fun for me." The precision control the gi affords — both in setting up the baratoplata and in managing opponents' defenses — makes the format a natural home for a technique that rewards exactness over raw athleticism.

Miyao has taught the baratoplata at seminars worldwide, extending its application to a broader grappling audience. The technique represents a meaningful evolution in his competitive identity — from the berimbolo-centered offense of his early black belt years toward a more submission-complete game built around a single high-percentage, high-difficulty finish.

Following their rise to international prominence, João and Paulo Miyao spent several years competing and training under the Unity Jiu-Jitsu banner in New York City. The association placed them at the center of a competitive team that included a number of high-level athletes and gave the brothers a base from which to access the major North American competition circuit.

In 2020, the Miyao brothers parted ways with Unity, with both citing unresolved issues as the basis for the split. The departure opened a transitional period — one in which the brothers continued competing at elite levels while charting a course toward full independence. The Unity years had provided a platform; what followed would be the construction of something they could call entirely their own.

In early 2024, João and Paulo Miyao launched Studio 1908 in Jersey City, New Jersey — a milestone that transformed them from competitors representing a team into owners building one. The academy gave the brothers full creative and operational control over their training environment, allowing them to construct a culture that reflected the values, methods, and work ethic that had defined their own development.

João teaches classes regularly at Studio 1908, bringing his obsessive drilling culture directly to students at every level. The same discipline that once had him sleeping on a gym floor in São Paulo now manifests in the precision with which he transmits berimbolo mechanics, baratoplata setups, and guard concepts to the next generation of grapplers. The gym serves both competitive athletes and general students, with the Miyao technical library available to anyone willing to put in the work.

The global coaching model that complements Studio 1908's home base came into focus in January 2026, when João documented a coaching day in Lisbon, Portugal. Across four sessions — a private at 3:00 pm, a second private at 4:02 pm, a group class at 5:01 pm, and another group class at 7:05 pm — he earned 1,950 euros in a single day. The post stood in contrast to broader community debates about instructor compensation and underscored the premium positioning Miyao has built as a global technical resource.

João Miyao's evolution from singular competitor to coach and mentor has been deliberate and grounded in the same analytical framework that shaped his athletic career. His approach to teaching — calm, stoic, and methodical — mirrors the laboratory-like quality that BJJ observers have long associated with his competitive preparation. He builds understanding rather than imposing technique, emphasizing control, position, and the reasoning behind each movement before the movement itself.

In 2022, Paulo Miyao announced a shift toward teaching, taking a head coaching role at Dream Art in São Paulo. João supported that direction, and the brothers' parallel transitions — Paulo toward a coaching-primary identity, João toward a balance of competition and instruction — reflected a shared recognition that their contributions to the sport extend beyond their own podium finishes.

At Studio 1908, João guides athletes from white belt fundamentals through high-level competition preparation, applying the same drilling culture that defined his own rise. His increasing selectivity in competition entries reflects not a retreat from the sport but a reallocation of energy — the same focused intensity now distributed across a roster of students rather than concentrated solely on his own game.

João Miyao's relationship with UFC BJJ became a subject of public attention in mid-2026 when a negotiation breakdown over a proposed rematch with Mikey Musumeci spilled into social media and broader industry discussion. The sequence began with Miyao competing at UFC BJJ against Jussier Formiga — a match he won, earning strong praise from Claudia Gadelha, who as of July 2026 serves as a key figure within UFC BJJ. Gadelha later recalled the aftermath warmly: "João went there, beat Formiga, fought very well, had fun all week, thanked me, was super happy, earned his money, and everything was fine."

The complications arose around a proposed Musumeci rematch — a matchup carrying significant history, as Musumeci had previously defeated Miyao five times. Gadelha described having managed Musumeci's repeated requests for the rematch by first booking Miyao against Formiga to build a narrative: "Hey, Mike, I'm going to bring him here. He'll beat someone. After he beats that person, then it makes sense to put you two back together, right? You've already beaten the guy five times. It's very difficult to sell this matchup."

When negotiations for the Musumeci bout began, Miyao's asking price came in far above what Gadelha and her partner expected — described by Gadelha as a figure "even a top MMA star doesn't get in Jiu-Jitsu," and substantially higher than what he had accepted to face Formiga. A timing conflict compounded matters: Miyao indicated he was away for a seminar and unavailable to discuss terms for one to two weeks, while the promotion required an answer within two days. Unable to reach agreement, Gadelha's partner Steven informed Musumeci that the match was unlikely to happen.

Musumeci subsequently posted on Instagram in a manner that implied Miyao's financial demands reflected a reluctance to compete against him. Miyao responded publicly, accusing Gadelha of leaking negotiation figures. Gadelha denied this directly: "Mikey doesn't even know what that number is. Only me, Steven [my partner], and João know." She attempted to resolve the matter privately, texting Miyao to speak directly, but according to Gadelha, he did not respond.

Gadelha's account acknowledged Miyao's business model — built around Instagram presence, brand deals, seminars, and selective competition — while framing the promotion's position in structural terms: "We're not UFC MMA, we're UFC BJJ. We have to stick to a budget within the business. And if I don't stick to my budget for the year, I'm screwed." On the prospect of a future Musumeci matchup, Gadelha was measured: "He was going to compete at UFC BJJ to compete against Mikey again. He's already lost to Mikey five times. So, to compete, if he hadn't had all this trouble going on social media and saying what he said, well, maybe, but I don't think it makes sense anymore."

The episode offers a clear window into the economics of elite competitive BJJ — the tension between a fighter's market value as an independent brand, the financial constraints of a promotion operating within a defined budget, and the reputational dynamics that shape high-profile matchmaking negotiations in a sport where the line between athlete and entrepreneur grows increasingly blurred.

João Miyao's competitive identity has always been built on technical precision rather than physical dominance — a foundation that has allowed his game to age with remarkable resilience. His preference for gi competition, stated plainly in a January 2026 Instagram interview as "Gi, for sure. I have more options. It's more fun for me," is not merely aesthetic but strategic: the gi amplifies the control-based, leverage-intensive techniques — particularly the baratoplata — that define his offensive game.

His grappling IQ manifests in his match approach: neutralizing an opponent's preferred sequences before imposing his own attack chains, creating a controlled problem-solving environment rather than a scramble. The methodology demands patience and spatial awareness that develop only through years of high-level competition and focused study.

Miyao reflects on competition with a humility that belies his decorated record. In that same January 2026 interview, he offered a perspective that captures his ongoing relationship with the sport: "Never give up," and, "I think I'm better today, but next competition my opponent can be better than me." The framing — improvement as a constant, superiority as never guaranteed — is entirely consistent with the laboratory mentality that has characterized his entire career, from the gym floor in São Paulo to the mats of Studio 1908 and seminar rooms in Lisbon.
