Pop idol group "Nogizaka46" has recently sparked a public awareness campaign focusing on mindful actions when giving and receiving commemorative flowers in Japan. This campaign comes as a reaction to many fans sending an endless stream of congratulatory flower stands to their idols, sometimes causing excessive waste and disorder. The supergroup is urging fans to be more conscious about the environmental and social implications of their token of affection.

Celebrities in Japan typically receive a plethora of flower stands from their fans to show support, particularly during concerts or commemoration events. It is deeply engrained in the entertainment industry and seen as a significant form of appreciation. However, issues such as waste management and the environmental impact are starting to be addressed by the celebrities themselves, prompting a change in this deeply rooted culture.

In the US or EU, fans show support to their idols through merchandise purchases, attending concerts and events, and online engagement. While the idea of sending flowers does exist, it isn't as widespread as in Japan. Environmental impact and sustainability are already popular topics of discussion and influence fan behavior.
