An explosive boom in the popularity of collectible stickers in Japan has led many store employees to express their growing frustration. This surge in demand has seen an unprecedented number of customers wrestling to get their hands on these stickers, subsequently causing strains on store staff. Despite the upshot in sales, these staff hold mixed feelings, as the hectic situations often disrupt regular store operations.

In Japan, these sticker collectibles are often associated with shopping campaigns or promotions. The appeal lies in the idea of "collect to get rewards," a marketing technique widely accepted in the country. It is not the mere collection that people care about, but the sense of achievement in completing the collection and the anticipation of the associated rewards. However, the frenzy surrounding sticker collection can sometimes spark public order concerns.

In the US or EU, collectibles and rewards programs are popular, but may not generally incite the same level of fervor seen in Japan. Instances of store employees being overwhelmed by the craze are fewer, hence, the trend is typically viewed as a fun, harmless pastime or marketing strategy, unless it reaches the scale of something like Beanie Babies or Pokémon cards in the past.
