His most notable achievement is the identification of programmed cell death protein 1 (PD-1), a discovery that has significantly advanced cancer immunotherapy.

In addition to his work on PD-1, Honjo has made substantial contributions to the understanding of cytokines, particularly IL-4 and IL-5. He is also credited with the discovery of activation-induced cytidine deaminase (AID), a crucial enzyme for class switch recombination and somatic hypermutation, which are essential processes in the immune response.

Honjo's scientific excellence has been recognized through numerous accolades. He was elected as a foreign associate of the National Academy of Sciences of the United States in two thousand one, became a member of the German Academy of Natural Scientists Leopoldina in two thousand three, and joined the Japan Academy in two thousand five.

In two thousand eighteen, Honjo was awarded the Nobel Prize in Physiology or Medicine, sharing this prestigious honor with James P. Allison for their collaborative work in cancer treatment.
