Ikigai: A Japanese concept to improve work and life

According to Hasegawa, the origin of the word ikigai goes back to the Heian period (794 to 1185). " Gai comes from the word kai ("shell" in Japanese) which were deemed highly valuable, and from there ikigai derived as a word that means value in living."

There are other words that use kai: yarigai or hatarakigai which mean the value of doing and the value of working. Ikigai can be thought of as a comprehensive concept that incorporates such values in life.

There are many books in Japan devoted to ikigai, but one in particular is considered definitive: Ikigai-ni-tsuite (About Ikigai), published in 1966.

Hasegawa points out that in English, the word life means both lifetime and everyday life. So, ikigai translated as life's purpose sounds very grand. "But in Japan we have jinsei, which means lifetime and seikatsu, which means everyday life," he says. The concept of ikigai aligns more to seikatsu and, through his research, Hasegawa discovered that Japanese people believe that the sum of small joys in everyday life results in more fulfilling life as a whole.
