Professional career

Sasaki had his debut fight on August 24, 2018, and won by TKO in the second round.[4]

Sasaki advanced to the 2019 East Japan Lightweight Rookie of the Year final, but abstained from the East Japan Lightweight Rookie of the Year final due to being unable to make weight.[citation needed]

On December 26, 2020, at "Kakeru Holdings presents A-SIGN.BOXING" held at the Sumida Ward General Gymnasium, he fought Aso Ishiwaki for the Japan Super Lightweight Youth Championship, and won by TKO in the third round in 2 minutes and 50 seconds.[5]
