March 20 is the International Day of Happiness , designated by the United Nations to recognize happiness as a universal human goal and to encourage the creation of inclusive and equitable societies that promote the happiness and well‑being of all.

This idea is closely linked to the promotion of the Sustainable Development Goals (SDGs), which aim to build a sustainable society where no one is left behind. In recent years, there has been growing global recognition that the scale of economic growth—measured solely by GDP—cannot fully capture the richness of a society. As a result, discussions on “Beyond GDP” have expanded worldwide, drawing attention to frameworks that emphasize people’s well‑being, the environment, and the quality of society. At JICA, efforts have begun to incorporate new evaluation perspectives that better capture people’s well-being.

These values align closely with the principles of the JICA Ogata Research Institute, which places great importance on human security—protecting the lives, livelihoods, and dignity of every individual. Below, we introduce some of the Institute’s initiatives that relate to people’s happiness and well-being contribute to these goals.

Working Paper | No.76 Happiness in Thailand: The Effects of Family, Health and Job Satisfaction, and the Moderating Role of Gender

Working Paper | No.79 Interdependent Happiness: Cultural Happiness under the East Asian Cultural Mandate

In order to examine how socio-economic status might undermine cultural happiness shared among East Asian cultural members, the concept of interdependent happiness - harmony with others, quiescence, and ordinariness - was measured using representative adults from Thailand living in both rural and urban areas. While objective socio-economic status showed negative correlation with the interdependent happiness, it showed a negligible correlation with general happiness.
