Retail Media Market: Japanese Convenience Stores Use AI to Create Novel Snacks

Japanese convenience store chains Lawson and FamilyMart are using AI in contrasting ways to develop new snack products. Lawson employs generative AI without sales data, using only the abstract prompt 'What on earth is this? But it's delicious' to generate unconventional ideas like a lemon-pickle tart. This led to three products launching in September 2026 in the Tokyo area. FamilyMart, on the other hand, feeds its AI with extensive point-of-sale data, analyzing past sales and product attributes to predict successful combinations, resulting in a sweet potato canelé. This data-driven approach reduces concept development time by about 20%. Both companies retain human oversight for final product decisions, highlighting AI's role as an idea generator rather than autonomous creator. This pragmatic integration in Japan contrasts with Western regulatory debates, showcasing AI's practical application in retail product development.
