What retail innovation has most significantly transformed the traditional Japanese omiyage (souvenir) market in the past decade?

Japanese 'omiyage' gift-giving tradition has evolved into a sophisticated retail phenomenon with significant impact on consumer psychology and brand loyalty. Unlike Western souvenirs, omiyage are typically local food specialties purchased as obligatory gifts for colleagues, family, and friends when returning from travel. This cultural practice has created unique retail ecosystems in Japan, with department stores dedicating entire floors to regional specialties and train stations featuring carefully curated omiyage shops.
