Arthur Nory Oyakawa Mariano is a Brazilian artistic gymnast, born September 18, 1993, in Campinas. A three-time Olympian, he won bronze on floor exercise at the 2016 Rio Games and became world champion on horizontal bar in 2019. Known for his technical precision and charismatic presence, Mariano remains a cornerstone of Brazilian men's gymnastics.

As of 2026, he continues to compete internationally, having represented Brazil at the 2020 Tokyo and 2024 Paris Olympics.

Mariano was born in Campinas to a Brazilian father and a Japanese Brazilian mother. His early athletic life began in judo, following his father's path, but a glimpse of a gymnastics class redirected his focus. After his parents' separation, he moved to São Paulo with his mother.

At age 11, he joined Esporte Clube Pinheiros, a prestigious sports club, and by 14 he had won the Brazilian Child Gymnastics Championship. He joined the senior national team in 2011 and competed at the 2010 Youth Olympics and the 2014 South American Games. In 2015, he placed fourth on horizontal bar at the World Championships, hinting at his future success. He also earned medals at the 2015 Pan American Games. [edit]

Mariano's breakthrough came at the 2016 Rio Olympics, where he secured bronze on floor exercise after Kohei Uchimura stepped out of bounds. That medal made him a national hero. In 2019, he reached the pinnacle by winning gold on horizontal bar at the World Championships, a feat he followed with a bronze on the same apparatus in 2022.

He has competed at three Olympics (2016, 2020, 2024), demonstrating remarkable longevity. Beyond the Olympics, he has earned medals at the Pan American Games in 2019 and 2023, adding to his 2015 haul. Training at Esporte Clube Pinheiros under Cristiano Albino, with Marcos Goto as national team coach, he remains a key figure in Brazilian gymnastics. [edit]

Mariano is seen as a charismatic and technically gifted gymnast who has elevated Brazilian men's gymnastics on the world stage. His Japanese-Brazilian background resonates within Brazil's Japanese diaspora community. A playful friendship with Simone Biles, who jokingly called him her 'Brazilian boyfriend,' has boosted his international visibility. He is known for his expressive routines and calm demeanor under pressure. [edit]

Arthur Mariano's global fame is a study in sustained resonance. As of August 2026, iFANN's Global Fame Engine has evaluated his standing but has not placed him in the published rankings, meaning he holds no current position among the Global Top 1,000 or any Top-100 scope list. This absence, however, belies a substantial international footprint. His renown is anchored in Olympic and world championship achievements, which have secured his place in gymnastics history. The 2016 Rio Games, where he won bronze on floor exercise, and his 2019 world title on horizontal bar, are touchstones that continue to define his public profile.

His fanbase, though without a formal name, is considerable and active. With approximately 1.3 million Instagram followers, he commands a digital community that engages with his journey, from training updates to personal milestones. His appeal extends beyond gymnastics, touching mainstream Brazilian culture and, through moments like the playful 'Brazilian boyfriend' episode with Simone Biles, reaching a global audience. That interplay of athletic excellence and charismatic accessibility has made him a fixture in sports media and a beloved figure among Brazilian gymnastics enthusiasts.

iFANN's evaluation reflects the nuance of his fame: significant, enduring, yet not currently quantified in the top tiers. His story, of resilience, openness, and consistent performance, ensures that his renown, while unranked, remains firmly established in the public consciousness.[edit]

Biles jokingly called Mariano her 'Brazilian boyfriend,' and after she kissed Efron, Mariano playfully called out Efron on social media, a moment that captivated teen media and amplified his international visibility.

Another iconic moment is his victory at the 2019 World Championships in Stuttgart, where he became world champion on the high bar, a milestone that remains a point of pride for his followers. His third Olympic appearance in Paris 2024 was historic as he competed as an openly gay athlete, with his boyfriend present, adding a layer of significance for LGBTQ+ sports fans.[edit]
