Ikigai (生き甲斐, Japanese pronunciation: [ikiɡai]) is a Japanese concept that means "a reason for being". The word refers to having a direction or purpose in life, that which makes one's life worthwhile, and towards which an individual takes spontaneous and willing actions giving them satisfaction and a sense of meaning to life.
The word consists of 'Iki' (to live) and 'gai' (reason). The term ikigai compounds two Japanese words: iki (生き) meaning "life; alive" and kai (甲斐) meaning "(an) effect; (a) result; (a) fruit; (a) worth; (a) use; (a) benefit; (no, little) avail" (sequentially voiced as gai) to arrive at "a reason for living [being alive]; a meaning for [to] life; what [something that] makes life worth living; a raison d'être".
Ikigai can describe having a sense of purpose in life, as well as being motivated. According to a study feeling ikigai as described by Japanese usually means the feeling of accomplishment and fulfillment that follows when people pursue their passions. Activities that allow one to feel ikigai are not forced on an individual; they are perceived as being spontaneous and undertaken willingly, therefore they are personal and depend on a person's inner self.
According to psychologist Katsuya Inoue, ikigai is a concept consisting of two aspects: "sources or objects that bring value or meaning to life" and "a feeling that one's life has value or meaning because of the existence of its source or object". Inoue classifies ikigai into three directions, social ikigai, non-social ikigai, and anti-social ikigai, from a social perspective. Social ikigai refers to ikigai that are accepted by society through volunteer activities and circle activities. An asocial ikigai is a ikigai that is not directly related to society, such as faith or self-discipline. Anti-social ikigai refers to ikigai, which is the basic motivation for living through dark emotions, such as the desire to hate someone or something or to continue having a desire to revenge.
National Geographic reporter Dan Buettner suggested ikigai may be one of the reasons for the longevity of the people of Okinawa. 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. In the year 2016, a book based on the Japanese concept 'Ikigai: The Japanese Secret to a Long and Happy Life' was published by Penguin Books, it was authored by Hector Garcia Puigcerver and Francesc Miralles. 
Although the concept of ikigai has long been in Japanese culture, it was first popularised by Japanese psychiatrist and academic Mieko Kamiya in her 1966 book "生きがいについて" (ikigai ni tsuite, On the Meaning of Life). The book has not yet been translated into English.
In the 1960s, 1970s and 1980s, ikigai was thought to be experienced towards either the betterment of society ("subordinating one's own desires to others") or improvement of oneself ("following one's own path"). In the 21st century however, ikigai's focus has shifted towards the self; instead of "self-sacrifice", the focus is on developing oneself.
According to anthropologist Chikako Ozawa-de Silva, for an older generation in Japan, their ikigai was to "fit this standard mold of company and family", whereas the younger generation reported their ikigai to be about "dreams of what they might become in the future".
A 2012 study in the Global Journal of Health Science suggested that having the feeling of ikigai influenced the functioning of the frontal lobe. Some studies[vague] showed that people who do not feel ikigai are more likely to experience cardiovascular diseases. However, there was no evidence of any co-relation with development of malignant tumors.
