Japanese retailers and food-service companies are selling summer-season "fukubukuro," or lucky bags, containing practical goods and coupons [1].

This shift represents a strategic move by businesses to attract customers who are increasingly focused on cost-saving measures and heat-wave protection during the summer months [2].

Traditionally associated with New Year celebrations, these bundles now include items such as cooling bags, branded merchandise, and food-coupon tickets [1]. The practice began experimentally around 2013 with department stores [1]. Since then, the trend has expanded to supermarkets, restaurant chains, and electronics retailers [1].

Several major brands have adopted the strategy this July. For example, Heart Bread began sales on July 10 [1]. The restaurant chain Ootoya started its offering on July 17 [1]. Ootoya's lucky bag is priced at 3,000 yen [2], but it includes coupons worth 3,300 yen, providing the customer with a 300-yen profit [2]. Other participating businesses include Royal Host, Freshness Burger, and the bakery Sun Germaine [1].

Economic commentator Takashi Sakaguchi said the rapid spread of these bags is due to a combination of recent cost-saving orientations and the demand for measures against extreme heat [1].

TBS caster Junna Yamagata said that while department stores trialed the bags around 2013, they have since become a standard project across various sectors, including supermarkets and dining [1].

Summer fukubukuro have become a standard project across various sectors.

The migration of the fukubukuro from a winter tradition to a summer staple reflects a broader adaptation in Japanese retail to combat inflation. By bundling essential heat-relief products with high-value coupons, companies are leveraging the 'value-for-money' psychology to ensure foot traffic during a season typically characterized by volatile consumer spending.
