A survey conducted by the Gurunavi Research Department found that 86% of respondents are conscious of reducing food waste, with such practices becoming more widespread at home and when dining out. The survey was conducted from 9 to 10 October 2026 among 1,300 Gurunavi members.
The Gurunavi Research Department announced that a survey of Gurunavi members found that 86% are conscious of reducing food waste. Women tended to be more conscious than men, with the rate among women aged 40 and over standing at approximately 50% to 70%.
Among the circumstances in which respondents had discarded food within the past year, "forgetting it existed and allowing it to spoil, or its expiration date passing" was the most common response, at more than 40%. Only approximately one-quarter of respondents said they had not discarded any food.
The most common household measure for reducing food waste was eating or using food even when its best-before date had passed by a small margin, at more than 60%. Nearly 50% said they preserve food for longer, including by freezing it. When dining out, "ordering only what can be eaten" and "eating everything served" each attracted responses in the mid-50% range, indicating almost equal levels of interest.
The survey was conducted from 9 to 10 October 2026 through a web-based questionnaire. Respondents were 1,300 Gurunavi members from across Japan.
Approximately 80% of respondents expressed an intention to use food-sharing services, while the rate of usage experience was highest among men in their 20s, at approximately 30%.
