Nozoe's main research interests lay in the study of natural products, especially those found in Formosa. Nozoe's documented work in Formosa concerned the chemical components of Taiwanhinoki, a native conifer growing in mountainous areas.[35] Nozoe determined a new compound, hinokitiol, from the components of this species and reported it for the first time in 1936 in a special issue of Bulletin of the Chemical Society of Japan.[36]
