Top seed: Muslim Gadzhimagomedov
The Russian is unbeaten since 2017 and rightly earns his status as the top seed heading into the heavyweight competition.
According to BoxRec, the 24-year-old has a 81-5 record as an amateur and is on a 45-fight win streak which includes a victory over Team GB's Cheavon Clarke.
In 2019, he won the World Championships and European Games and is favourite to add another medal this summer in Japan.
Most talked about: Cheavon Clarke
Possibly the most charismatic fighter at the Olympics this summer. His personality matches his hunger and dedication to succeed under the Team GB banner.
Clarke was previously working as a lorry driver delivering to Homebase and B&Q from 2014 to 2016 before joining Team GB.
Since being picked by Team GB, Clarke has won a silver medal at the 2017 European Championships as well as bronze at the 2019 European Games in Minsk, 2018 EU Championships in Valladolid and the 2018 Commonwealth Games in the Gold Coast.
Two to watch: Vassiliy Levit, Julio Cesar La Cruz
The Kazakh fighter will be looking to go one better in Tokyo after winning a silver medal at the 2016 Olympic Games in Brazil.
In reality, Levit should have won the final against Evgeny Tishchenko but lost via unanimous decision. Most people thought Levit had won all three rounds and claimed it was a robbery.
The 33-year-old has won multiple medals in the Championships and World Championships between 2017 to 2021. His record is 88-22.
It will be interesting to see how La Cruz of Cuba gets on in Tokyo. Fast hands, quick head movement and flashy, LA Cruz is a defensive boxer who has an incredible amount of skill.
In 2016, he won light heavyweight gold at the 2016 Olympics and has a haul of gold medals including 2013 and 2015 World Championships.
His record is 218-14 and has only been knocked out once in 14 defeats, losing to Matchroom Boxing's prospect Khalil Coe.
