Solo Consumption of Food

Single men and women in their 20s and older

Have you ever felt this sense of unease in your daily work?
-The sizing and the packaging design of products for single-person households rely too heavily on past experience.
-Despite targeting specific age groups, efforts often fail to yield the desired results.
-There is a lack of data on the actual behavior of single-person households when planning shelf layouts and promotional strategies.
When addressing these challenges, individual factors such as taste, price, and recognition alone are often insufficient to explain the situation. The underlying issue may lie in how we perceive single-person households. The “solo household” market accounts for approximately 40% of all households in Japan. However, traditional analyses based solely on “gender and age” can no longer fully explain their choice behaviors or purchasing decisions. In this report, we reexamine the dietary behaviors of single-person households through three key axes:1) demographics, 2) values, and 3) actual behaviors and living environments. We also explain why conventional approaches are becoming less functional. “Why don’t health-conscious seniors buy prepared foods?” “Why do busy young people cook for themselves?” We visualize the “lifestyle circumstances” and “honest thoughts” unique to single-person households—factors that cannot be revealed by attribute data alone.
