Ikigai (生き甲斐) is a Japanese concept that means “a reason for being.” It is similar to the French phrase Raison d’être. Everyone, according to Japanese culture, has an ikigai. Finding it requires a deep and often lengthy search of self. Such a search is important to the cultural belief that discovering one’s ikigai brings satisfaction and meaning to life. Examples include work, hobbies and raising children.
