In response to increasing health concerns, Japanese airlines urge passengers to refrain from eating nuts on board. The plea comes amidst a rising number of emergency landings due to severe allergic reactions. On the other hand, individulas who aren't allergic question the fairness of this restriction.

Japan has a high value for collective welfare and adheres to a societal value system where the group's well-being takes precedence over individual preferences. This agrees with the 'no-nut' policy which functions on the principle of preventing potential health risks faced by allergic passengers.

In the United States or European Union, airlines handle this somewhat differently. Some airlines have specific in-flight policies such as nut-free zones while others may stop serving nuts altogether. However, the total prohibition like Japan's request is less common.
