In episode 17 of the Ikigai podcast, Assistant Professor Shintaro Kono shares his research results from a qualitative study on how Japanese university students experience ikigai via interpersonal relationships. 

Theorizing the Interpersonal Aspect of Ikigai
Ikigai is strongly influenced by "ibasho"; authentic relationship. In such relationships, students felt that they could be true to who they were and that their close others genuinely cared about them. 

In summary, Shin's research and resulting theory suggest that having authentic relationship is characterized by two distinct types of subjective perceptions; self-authenticity and genuine care. Authentic relationship was often developed and maintained through two modes of interaction; "experiencing together", and "communicating experiences". Lastly, these interactions were conditioned by echoed values and trust.
