Suzuki earned his doctorate from Tohoku University in 1974, supervised by Masatoshi Koshiba.

[2] The Kamiokande-II experiment detected a burst of neutrinos from Supernova 1987A, the first observation of this kind, winning the research team the Asahi and Bruno Rossi prizes.

[3] The KamLAND experiment was the first to detect geoneutrinos generated by the decay of radionuclides deep inside Earth.

These observations provided the first direct measurements of the abundance of geoneutrino-producing elements and their spatial distribution in Earth's interior, marking the start of a new field of neutrino geoscience.

[6] Suzuki received the Japanese Medal of Honor with purple ribbon in 2005,[7] the Bruno Pontecorvo Prize in 2006,[8] and the Breakthrough Prize in Fundamental Physics in 2016, shared with investigators from the KamLAND, Super-Kamiokande, K2K / T2K, Daya Bay, and Sudbury neutrino observation consortia.
