Psychology in Japan has a long history of importing psychological knowledge from Europe and the United States since the 18th century. The development of the field has strongly been impacted by sociohistorical factors of modernization and occupation, and it has been struggling with the attempts to integrate the Western influences and traditional worldviews on human minds and mental health. Some efforts have been made to incorporate Japanese traditional value systems into psychological knowledge and practice; however, the Western influences on the knowledge production and human services are still very prevalent. While the world is becoming closer with each other and the worldviews from various parts of the world are becoming more intertwined with each other, it is becoming more difficult to pinpoint the appropriateness and adequateness of certain psychological knowledge on our minds and mental health. In this presentation, the presenter will share her journey of being a scholar from Japan which has a history of being a colonizer and whose academic discipline has been influenced by neocolonial trends, present the impact of Western-centric science on traditional worldviews, and discuss the importance of having critical lens on looking at socio-cultural-historical factors on human minds.
