This study examines Japanese consumers’ innovative behaviors toward adopting electric vehicles (EVs) and the differences between male and female car owners in the adoption process. A theoretical framework is formulated based on six constructs: passive innovation, active innovation resistance, cognitive innovativeness, affinity for newness, social innovativeness, and actualized innovativeness. The premise of the study is to investigate whether these key independent constructs differentially influence Japanese car owners’ actualized innovativeness to adopt electric cars. This research seeks to address the following research questions.
