Together with NISSIN FOOD PRODUCTS CO., LTD., we drew on a large-scale survey of 30,000 general consumers to launch the Well-being Improvement through Food and Sleep Project. In a one-month evaluation by employees of both companies, we demonstrated concrete effects, including about a 10% improvement in well-being indicators, increased productivity, and reduced insomnia risk. Based on these insights, we developed the Happiness Type Diagnosis that classifies senses of value concerning happiness into seven character types. By proposing manageable “golden actions for food and sleep” (recommended actions) aligned with individual senses of value, we will support people’s steps aimed at finding happiness that is true to themselves and making daily life more comfortable and fulfilling.
