What ikigai actually is
In Japanese usage, ikigai (生き甲斐) is what makes life feel worth living, and it is strikingly ordinary: morning coffee, a grandchild, the allotment, craft done well, friends expected on Thursday. The founding scholarly treatment is psychiatrist Mieko Kamiya's Ikigai ni Tsuite (On the Meaning of Life, 1966), which distinguishes the sources of worth (ikigai) from the feeling of worth (ikigai-kan) and locates both closer to everyday experience than to grand mission. Nothing in the concept requires that your ikigai be your job, be singular, or be monetisable; for most people it is plural, small, and free. Epidemiology has taken the concept seriously: the Ohsaki cohort study followed over forty thousand Japanese adults and found that those reporting ikigai had lower mortality over seven years, an association worth exactly what cohort associations are worth, and still a striking one.
