Nadaka Yoshinari is often compared to his compatriot Naoya Inoue, the undefeated genius of Boxing rings (World Champion WBC, WBA, IBF, WBO), Nadaka excels in the art of Muay Thai.

At only 23 years old, he is considered the best Japanese fighter of Muay Thai, having already won an impressive total of 14 belts.

Born on January 8, 2001 in the city of Yokosuka, in the prefecture of Kanagawa in Japan, Nadaka Yoshinari is truly a phenomenon on the rings, showing admirable skill and determination at such a young age. His succession of victories and his illustrious record testify to his exceptional talent.

At the age of 4 years, under the influence of his older brother, he began practicing karate, thus laying the foundation for his martial arts training. From his third year of primary school, around the age of 9 years, he then started in Kick Boxing, where he accumulated many fights as an amateur.

The discovery of Muay Thai during his first trip to Thailand marked a turning point in the life of Nadaka Yoshinari. At the age of 11 years, he made his ring debut in this emblematic country of Muay Thai.

His first fight in Thailand ended in a points loss against an older opponent who was 5 kg heavier than him. Despite this loss, this experience was revealing for Nadaka, offering his a deep appreciation and passion for the sport.

From then on, Nadaka fully engaged in the practice of Muay Thai, determined to become a star of the rings.

Nadaka’s devotion to Muay Thai led him to make a decisive choice: to devote himself entirely to the practice of this sport. He decided to continue his studies by correspondence and enroll in a high school, located near his training club in Yokohama. Although his Muay Thai workouts are very demanding and take up much of his time, he manages to juggle his studies and workouts.

Nadaka managed to obtain his third year degree from the “Renaissance High School” (equivalent to the Bac in Japan), despite the challenges and sacrifices inherent in the intensive practice of Muay Thai.

Nadaka also had the opportunity to train in a traditional boxing camp in Thailand to discover Muay Thai at its source.

In Japan, he was trained at Eiwa Sports Gym by Professor Natsuo Nakagawa, a renowned Kickboxing and Muay Thai club located in Yokohama, with more than 400 members today.

Nadaka benefited from an exceptional training in Muay Thai thanks to Professor Khundong Por Thawatchai, a former Thai boxer settled in Japan for fifteen years. It was under his tutelage that the young Nadaka was formed and trained until winning the supreme title in a large stadium in Bangkok.

Khundong has also trained other Japanese talents who have become renowned champions, such as Ryuya Eiwa Sports Gym (105 lbs Radja Champion, 105 lbs Thai Champion, 105 lbs IBF Muay Thai World Champion, 105 lbs WPMF World Champion), Shimon Eiwa Sports Gym (130 lbs Thai Champion) and Asahi Eiwa Sports Gym (135 lbs WMC World Champion, 135 lbs IPCC World Champion, 122 lbs WBC World Champion).

The Thai media recognize the Japanese champions of Eiwa Sports Gym as high-level athletes, up to the Thai champions in the field of Muay Thai. The fact that three Japanese champions from the same club have won Thailand Championship titles is unique in the history of Muay Thai

Nadaka is now being prepared by former ring star Pakorn Sakyothin (Lumpinee Champion, Radja Champion, WMC World Champion, WPMF, Best Boxer of the Year 2013 The Sports Authority of Thailand). Thai Pakorn has been coaching at Eiwa Sports Gym for three years.
