A surprising study reveals that less than 90% of Japanese women in their twenties own knives. This decline may be reflective of a shift in the country’s culinary lifestyle, where more young adults are choosing other methods to prepare their meals or opting to eat out more often. Further analysis is needed to understand the underlying reasons behind this decrease in knife ownership.

Home cooking is a critical aspect of Japanese culture, with traditional recipes passed down through generations. As such, the news of this significant drop in knife ownership could indicate a shift in societal behaviors. It might also reflect concerns over the safety of knife possession in urban areas.

In contrast, there are no publicly available statistics measuring knife ownership in the US or the EU as it's not usually seen as significant data. However, Western culture tends to see cooking at home as an economical and healthier alternative to eating out. Therefore, knife ownership would presumably be quite widespread among young adults.
