Komehyo leads generative AI recommendations for brand purchasing

A September 2026 study by Branding Works reveals that Komehyo is the top-recommended brand purchase service when queried by generative AI. The company achieved a 94.4% mention rate, ranking first across both ChatGPT and Gemini.

Other notable mentions in the ranking include Nanboya (85.2%), Baisel (81.5%), and Brandear (66.7%). The study highlights that different AI models favor different companies; for instance, Gemini showed significantly higher mention rates for Nanboya and Brandear, while ChatGPT was more likely to mention Second Street and Kaitori Daikichi.

AI responses typically categorize services into three main criteria: on-site purchase support, ease of home delivery, and store accessibility/convenience. The research suggests that as consumers increasingly use AI for service recommendations, companies must optimize how they are perceived within these specific categories to maintain visibility.
