2. Samuel Nagai’s Biography

Samuel Nagai was born in Manés, a small place near Manaus, Brazil, on May 26, 2000. He is the brother of famous grappler Jackson Nagai. Nagai gained incredible respect as a competitor by defeating some of the best fighters, including Gutilhery Barbosa, Italo Moura, and Jonatha Alves, at the 2018 IBJJF World Championship. Samuel Nagai is now a BJJ black belt.

2.1. Early Life

Nagai spent his early life with his brother in Manés. When they were younger, their parents moved to Japan on a working visa, which they got easily because Nagai’s great-grandfather was a Japanese national. Then they also moved with their family to Japan when he was eight years old. The Nagai family settled in Japan; both brothers learned the Japanese language easily and got into the best schools where they excelled.

2.2. Introduction to Jiu-Jitsu

In 2010, some unfortunate events occurred in Nagai’s household, which led both brothers to BJJ. Their father left their mother, abandoning them too. Nagai started jiu-jitsu with his brother, Jackson, to protect his loved ones because their father assaulted their mother while leaving, which developed many insecurities in them.

2.3. Instructors

Nagai started his jiu-jitsu career with his first instructor, Emerson Noriaki. He has also trained with Junior Handa and Marcos Souza, while he was in Japan.

2.4. Promotion to Green Belt

Nagai was promoted to the Green Belt under Junior Handa and Marcos Souza while he lived in Japan.

2.5. Moved Back to Manaus

Nagai, with his family, moved back to Manaus, Brazil, after being promoted to the green belt. After their return to their hometown, the brothers started training with Marcio Pontes of Nova Uniáo. Later they also trained with Carlos Holanda, who became a great part of Nagai’s success.  

2.6. Participation in World Jiu-Jitsu Championship

While Nagai was training with Holanda, a close friend of Holanda, the former IBJJF World Champion Gabriel Moraes, met with the Manaus state governor and asked him to help take the Nagai brothers to the World Jiu-Jitsu Championship in California. At that tournament, Nagai and his brother demonstrated exceptional skill and unparalleled talent. That success gave them the much-needed exposure to the BJJ world. 

2.7. Checkmat Academy Invitation

Nagai and his brother got invited to the Checkmat Academy in California after being acknowledged at the IBJJF World Championship in California. They took classes with Lucas Leite in the academy.

2.8. Promotion to Black Belt

In August 2020, Nagai was promoted to the black belt under Keiser Giráo. It was the first time he experienced jiu-jitsu without his brother. After that, Nagai participated in various BJJ events and won many medals.

2.9. Competitive Accomplishments

Nagai competed at various BJJ events in colored and black belt divisions. He is the 2023 IBJJF World Champion 2023 and the 2020 IBJJF Pan American Champion. He won a gold medal in the UAEJJF Grand Slam and in the FJJA Amazonas State as a colored belt. As a brown belt, he also won the LBS Championship twice.
