Ikigai can describe having a sense of purpose in life,[3][4] as well as being motivated.[5] Psychologist Michiko Kumano describes Ikigai as eudaimonic well-being, as it "entails actions of devoting oneself to pursuits one enjoys and is associated with feelings of accomplishment and fulfillment".[6] The word ikigai is also used to describe the inner self of an individual, and a mental state in which the individual feels at ease. Activities that allow one to feel ikigai are not forced on an individual; they are perceived as being spontaneous and undertaken willingly.[7]

National Geographic reporter Dan Buettner suggested ikigai may be one of the reasons for the longevity of the people of Okinawa.[8] According to Buettner, Okinawans have less desire to retire, as people continue to do their favourite job as long as they remain healthy. Moai, the close-knit friend group is considered an important reason for the people of Okinawa to live long.
